Beer Cellar Statue - Creality Sermoon P1 IR mode

This statue is part of a beer cellar entry. Only noticed it by chance when going for a walk.

Scanning

Scanning was done with the Sermoon P1 in large IR mode with geometry tracking. I moved around the statue in circles and in a second pass after checking for coverage I filled in gaps for the overhangs. With initial firmware versions the P1 only could do 5-7fps in IR mode standalone, with the latest version it reaches a stable 19-20FPS. With the increased speed the scan only took roughly 5min without any tracking problems.

Post-Processing

For post processing I first transferred the scan data from the P1 to my workstation. You can either do it by cable where a nice import menu opens or over WiFi where you select the project on the scanner, join the hotspot of the scanner with your PC and send it to the PC (option I chose, simply less cables and quite fast with up to 120MB/s from testing). I then fused the scan at 1mm with 25% noise removal to retain detail (default noise removal tends to be a bit high) and meshed it with default settings. Quicksurface was used to align the scan and reduce triangle count.

Result

Best have a look at Sketchfab, quite content with the result. Finally IR mode is a joy to use standalone, hope they will bring hybrid geometry and texture tracking at some point.

Revopoint POP 4 Cold-Shoe adapter for smartphones holders

Printables Link: https://www.printables.com/model/1736950-revopoint-pop-4-cold-shoe-adapter-for-smartphones

When seeing the POP4 and reading about the standalone scanning support with the app or screen mirroring while scanning with a PC I immediately had the urge to create a nice solution for mounting a smartphone to the scanner. Could've used the default approach of putting it between battery and scanner like on the MetroY wireless kit but I prefer it to be top mounted.
So I jumped in Quicksurface and created this mount. It is attached with some reversible double-sided tape to the scanner and accepts any cold-shoe smartphone holders. Best thing: It still fits in the original case and be comfortably used with the mount attached.
Scan was designed around my 3d scan of the POP4, was not necessary but helped with positioning and sizing.

Printing is best done from PETG or ABS. YOu may want to roughen up the surface of the print before attaching the double-sided tape.

Smartphone Mount Used

Any other cold shoe smartphone mount should also work, just like this one. Has endless swivel points for adjustments. https://www.smallrig.com/de/smallrig-Metal-Phone-Holder-with-Cold-Shoe-Mount-4382.html

Anatomical Skull scanned with Revopoint POP4 in all Scan Modes

My trusty antomical skull of often one of the first objects to scan when testing a new scanner. With the POP4 I decided to scan it in all scanning modes. Already did something similar with the scan bench but wanted a more organic shape with a lot of deep crevices to capture. Due to the quite short distance between the cameras I initially assumed hole scanning performance would be very hood, especially with laser mode. And what can I say: it is very much so.

Scanning

POP4 has five scan modes:

  1. Laser (parallel lines)
  2. Laser (single line) --> mostly used in combination with parallel lines since the laser modes can be changed on the fly
  3. Full-Field HD (IR light in comparioson to MetroY Pro which uses blue light an can capture more detail due to this fact)
  4. VCSEL (typical IR point splatter, same principle as face-ID on an iPhone)
  5. Hybrid HD (combination of Full-Filed and VCSEL, aims to combine benefits of both and is placed right in betwen. Not as much detail as full-field but nearly as fast as VCSEL mode. So basically right in the middle.).

The scans were captured with wired connection to my workstation to capture data fastest (difference between wired and wireless is marginal but since no external power brick is needed the setup is nearly as easy as wireless).
For laser mode marker tracking was used. The skull was placed on a turntable with marker geometries placed around it to allow scanning from shallower angles (as seen in last picture). The resolution was set to 0.15mm in laser mode and exposure was adjusted so the skull wasn't overexposed. For laser mode I used a combination of cross and single line mode, changing them can be done by first using the "M"-button to select the mode slector and then plus and minus to switch modes. Single line mode was especially helpful the nose cavity and eye sockets, but even in cross-line mode it beat most of the other laser scanners I tested for scanning holes. Skull was scanned from top and bottom in two scans for laser mode and later merged.
The three IR modes were done in feature tracking (marker tracking is not yet supported for hybrid and VCSEL). All three were done in the high-accuracy preset with the use of AI segmentation. This alloed me to simply hold the skull in my hand and rotate it while scanning without the scanner picking up my hand holding it. Tracking also seems to be improved quite a bit on the POP4, normally the backside of the skull is quite hard ot scan in feature-tracking since it is quite uniform. Pop4 didn't loose tracking while spinning the head around in the IR modes.
All scans were performed until full data quality was reached in the live-view while scanning.

Post-Processing

For all scans processing was done using either a resolution of 0.1mm or as close to it as possible (Hybrid and VCSEL only go down to 0.2mm). The processing steps are point cloud generation, overlay detection and meshing. After exporting the meshes I used Quicksurface to align the meshes to the coordinate system and each other. The scans had to be reduced to allow upload to Sketchfab (just under 4M triangles will result in a 100MB ply when exporting from Quicksurface).

Results

Comparing the four scans results are mainly as expected and consistent with the scan bench: Laser privides the highest quality scan, followed by full-field, then hybrid and VCSEL last. This also shows what modes are meant for which use cases: Laser for high detail or small parts as well as tasks which require high accuracy whereas VCSEL shines with larger parts. As an concrete example full-field IR for face scans whereas VCSEL is for the full body.
Looking at the eye sockets and nasal cavity I'm very much impressed. All modes managed to capture the whole eye cavity and even the conchae. Same pattern continues on the bottom. One remark about full-field on the POP4 in comparison to the MetroY Pro full-field mode which uses blue light and supports the dual axis auto turntable: The maximum detail of the MetroY Pro can reach in this mode is much higher but especially or orgnaic parts the IR light source of the POP4 may be beneficial (e.g. when scanning a human). ‚

Revopoint POP 4 3D Scan - in case you want to design some accessories

Printables Link: https://www.printables.com/model/1736941-revopoint-pop-4-3d-scan

Did a quick scan of the POP 4 including the battery handle so you can design some accessories for it (I'm currently creating a cold-shoe mount for a top-mounted smartphone holder). Know the hastle when I got my first scanner and couldn't scan it.
Scan was created with the MetroY Pro in laser mode (resolution of 0.3mm). Applied some scan spray to the front where the lenses are so I can capture the actual geometry. Fused, aligned the top and bottom half scans and meshed in default parameters.
Battery grip was scanned as a separate part with one additional scan of it attached to allow later alignment in Quicksurface which was used to align all scans to the coordinate system and symmetry planes.

Quick first test of Markerless Laser - Creality Sermoon P1

This is just a quick test I did when I saw the Sermoon P1 finally supports markerless laser scanning. Currently it is only possible when connected wired to a PC which in a bit inconvenient. Hopefully they can implement it wireless or even standalone but no official statement regarding this.
Scan was done with my trusty anatomical head at 0.25mm resolution, scan speed was a steady 30FPS (similar to to max IR speed). A few more points I noticed:

  • tracking works very well, still with the limitations of feature tracking of course
  • Screen mirroring to the scanner is still missing
  • Performance was a stable 30 FPS for my setup (7950X, 128GB RAM, 5070Ti)
  • Ressource usage while scanning was ok: 20% CPU, ~19GB RAM and 40% GPU usage
  • Had to reduce automatic exposure a bit since I was scanning on a black table Scan came out quite good, scanning takes a good bit longer than marker based scanning (30 vs 80fps (wireless))

Bronze Statue of Horse - Einscan Rigil IR mode

Recently scanned quite a few statues at a park. This one is a horse next to a priest on a decorated socket. Total length is roughly 4.4m with the benches on both sides polished smooth due to people sitting on them. Scan was done outdoors whilst it was slightly overcast, aka best weather for texture scans.

Scanning

Scanning was done in IR large mode with a target resolution of 1.5mm. For tracking I only used geometry (also tried hybrid with texture but the bright sky behind the statue was quite a challenge for texture tracking). I created one scan to capture the whole socket of the statue until I reached to 8k frame-limit in standalone mode and another scan to capture the horse and priest. The scans combined took roughly 20min to capture. When performing large scans I try to mentally segment the models and scan segment per segment to keep track of what I've already scanned. Simply faster than looking on the scanner.

Post-Processing

For post processing I first transferred the scan data to my workstation using the wired connection (project size was 26GB and wired is simply faster than wireless, process for file transfer is luckily similar for both modes). Then I generated the point clouds for both scans and used automatic alignment between the two scans. Meshing was done with default settings and scan came out to roughly 20M triangles, reduced it within ExScan Rigil to under 4M and performed color mapping again. Then used the build-in alignment option to align the textured scan and exported.

Result

Mesh quality of the scan is excellent, especially the texture came out great. Also haven't notced any orange-peeling or overlap where the two scans were merged. Best have a look yourself in the pictures or sketchfab.
Sadly couldn't capture the top-most parts due to my arms being too short. Maybe I will design some sort of pole mount for the Rigil at some point in time.

Bronze Statue of Woman - Einscan Rigil IR mode

Recently scanned quite a few statues at a park. One of the most heart-warming ones was this woman or as I would call it "mother-earth" statue, kids often climb on it and sit in the center indenture. The statue is roughly 2.2m long and made from bronze with some parts polished shiny due to people touching it constantly.

Scanning

Scanning was done in IR large mode with a target resolution of 1mm. For tracking I only used geometry (surprised it kept tracking even on the relatively constantly curved back side). Could also have used hybrid tracking with texture added but with the harsh sunlight it would have caused more issues than advantages. The scan conditions in general were quite difficult: Bright sunlight from above and shiny metal on the statue. I did the initial pass around the statue with auto exposure and later switched to manual exposure to turn it a bit down to fill in the very reflective areas. When having reflections on the part it helps simply moving around to also move the reflections until everything is covered. All was done in one scan, roughly 5min.

Post-Processing

For post processing I first transferred the scan data to my workstation using the wired connection (simply faster than wireless, process for file transfer is luckily similar for both modes). T then generated the point cloud and meshed it with default settings. Scan came out to roughly 15M triangles, reduced it within ExScan Rigil to under 4M and performed color mapping again. Then used the build-in alignment option to align the textured scan and exported.

Result

Mesh quality of the scan is excellent for the quite hard scan conditions, even the shiny polished feet were captured. Only the texture is a bit blown out from the top side where it was directly lit from the sunlight. Maybe setting a manual texture camera exposure would have helped to mitigate this issue.

Short Reminder to Calibrate your 3d Scanners (with example)

With this example I want to highlight the difference between uncalibrated and calibrated scanners any why calibration is not only an optional step.
For this I did two scans of a shelf in my workshop: uncalibrated and calibrated. Both use the same scan settings (large IR mode with texture tracking), scanned until data quality is reached and processed in the same way.
The Sermoon P1 has the option to completely delete the current calibration data from the UI and basically reset the camera calibration to factory default for the scanner. This is the "uncalibrated" starting point for the first half of the test. Then I do a full calibration of the scanner (scanner already warmed up due to first scan, otherwise when starting with a cold scanner give it a few minutes before calibration to warm up) and perform the second calibrated scan. Will do a similar test for laser mode in the near future when I have time.

Results

I mean look at the pictures: Mesh of the uncalibrated scan is extremely rough and texture doesn't match at all.

VW Golf 8 Variant Trunk - Einscan Rigil IR

Another trunk to fit custom equipment in (mainly IT hardware). There are options to buy or get CAD data of vehicles but sometimes they can be a bit vague and doing a quick scan by myself still is the option I trust most (maybe at some point I will splurge on a used Freescan Nova, who knows. For now the Rigil does all I need).

Scanning

Scanning was done in standalone IR mode at 1mm resolution and markerless tracking. No textures were captured which led to a framerate of roughly 24FPS (with textures more like 20). No special preparation was done, scanned at an outside storage area. Tracking worked fine, for the roof I had to work up from the sides to use existing geometry as reference. Whole scan took roughly 5min including climbing in the trunk to scan the lid closed.

Post-Processing

Default processing at unwatertight and recommended settings. This includes point cloud generation on my PC and then meshing. Later used Quicksurface for fine alignment of the trunk using a symmetry plane and two automatically fitted reference planes. Also separated the trunk lid as a separate part for better usability (sketchfab sadly includes bot, simply easier for upload).

Revopoint POP4: AI Segmentation Tested and Explained

In my initial test the AI segmentation quite surprised me so I wanted to try out the different segmentation modes a bit more and give you an idea on how to use the mode with Revo Scan 6. Main application for me will be scanning on a crammed workbench but only wanting the object itself used for tracking/prevent capture of data I don't need. This is due to the fact that the segmentation not only prevents unwanted date from being captured (like a static object next to one on a turntable) but it also doesn't use the segmented-out data for tracking.

What's your opinion about using an engine block as a standard geometry to compare scanners?

Picture as an example of what I think about using. Currently I mainly use the scan bench and my trusty anatomical skull but I'm still missing larger parts in my tests.
Engine block came to my mind: mechanical part so quite interesting for reverse engineering tasks, suitable for both marker scans and feature tracking (scan bench simply isn't the best for feature tracking). Markers would be placed permanently on the block so layout stays the same across the beard.
Plan is to also upload the scan results to Sketchfab so people scan directly compare the results.

Open for further ides on how to use it and how to test scanners.

Revopoint POP4: Mobile Scanning without a PC tested

Finally I could test the standalone smartphone scanning of the POP 4. Standalone currently supports all the IR mdoes (full-field, VCSEL and hybrid). The smartphone I used was a Samsung Galaxy S25 Ultra for reference. With this I reached a stable 14 FPS in VCSEL and hybrid mode. Full-Field reached 10 FPS. Scan settings and processing are quite similar to the pc scanning program so not much time needed to get used to using the app.
Scanning it sellf feels very smooth, this includes also tracking and gerneral app performance. Didn't notice it wasn't a final release yet. Main thing I hope for: Support for laser scanning in mobile mode, even if it would be only single line mode. Not having the option at all can be quite limitnig in some scenarios and with the POP4 being this compact I see it as a to-go tool inside my travel-case.

Regarding my mobile scan setup: I did a slight modification by creating a clod-shoe mount for the POP4. This allows me to attach a nice smartphone holder to the top since I wanted a way to mount the phone on the scanner. Would say this is the "ideal" solution for this goal.

Scan Bench scanned with Revopoint POP4 in all Scan Modes

The ScanBench is an open standard to compare 3d scanner performance and is intended to be more tailored to mechanical needs instead of miniature scanning like the OpenScan Benchy: https://www.printables.com/model/1445865-scanbench-the-benchy-for-3d-scanners

I am aware that 3d printing the object will not be suitable to determine accuracy of the scanner but at least for me I will be scanning my printed version (0.4mm nozzle, 0.1mm layer height used) with the scanners I have access to so you can determine relative performance.

Scanning

POP4 has five scan modes:

  1. Laser (parallel lines)
  2. Laser (single line) --> mostly used in combination with parallel lines since the laser modes can be changed on the fly
  3. Full-Field HD (IR light in comparioson to MetroY Pro which uses blue light an can capture more detail due to this fact)
  4. VCSEL (typical IR point splatter, same principle as face-ID on an iPhone)
  5. Hybrid HD (combination of Full-Filed and VCSEL, aims to combine benefits of both and is placed right in betwen. Not as much detail as full-field but nearly as fast as VCSEL mode. So basically right in the middle.). My goal was to test all of them against one gemoetry as I will also do with my anatomical skull (or already did).

The scans were captured with wired connection to my workstation to capture data fastest (difference between wired and wireless is marginal but since no external power brick is needed the setup is nearly as easy as wireless).
For laser mode and FullField marker tracking was used. The scan bench was placed on a turntable with marker geometries placed around it to allow scanning from shallower angles (as seen in last picture). The resolution was set to 0.15mm in laser mode and exposure was adjusted so the white print wasn't overexposed. For laser mode I used a combination of cross and single line mode, changing them can be done by first using the "M"-button to select the mode slector and then plus and minus to switch modes.
Full-Field mode was done similar to the laser mode with the high accuracy preset and manual exposure.
The two other IR modes had to be done in feature tracking since marker tracking is not yet supported in these modes. Both Hybrid and VCSEL were done in the high-accuracy preset without the use of the AI segmentation feature since the stark contrast between black turntable and white part already created a segmentation.
All scans were performed until full data quality was reached in the live-view while scanning.

Post-Processing

For all scans processing was done using either a resolution of 0.1mm or as close to it as possible (Hybrid and VCSEL only go down to 0.2mm). The processing steps are point cloud generation, overlay detection and meshing. After exporting the meshes I used Quicksurface to align the meshes to the coordinate system and each other. The scans had to be reduced to allow upload to Sketchfab (just under 4M triangles will result in a 100MB ply when exporting from Quicksurface). For example the FullField scan had 40M triangles

Results

Comparing the four scans results are mainly as expected: Laser privides the highest quality scan, followed by full-field, then hybrid and VCSEL last. This also shows what modes are meant for which use cases: Laser for high detail or small parts as well as tasks which require high accuracy whereas VCSEL shines with larger parts. As an concrete example full-field IR for face scans whereas VCSEL is for the full body. Holes were no problem for the POP4. In laser mode it even managed to capture the small threaded rod.
Looking at the deivation of the IR scans realtive to the laser scan the trend is quite clear. Full-field and hybrid are very close (mostly within 0.1mm), VCSEL has more deviation.
One remark about full-field on the POP4 in comparison to the MetroY Pro full-field mode which uses blue light and supports the dual axis auto turntable: The maximum detail of the MetroY Pro can reach in this mode is much higher, I put the link to this scan in the next section. Best compare for yourslef. If your goal is scanning miniatures you may want to consider the MetroY Pro or Ultra over the POP4.

Gold Coin: Scanning Comparison Einscan Rigil vs Einstar Rockit

I want to start a series of more directly comparing 3d scanner performances by using "hopefully" commonly known parts as scan objects. After starting with a 50ct coin without scan spray I now want to test the Rigil and Rockit with a gold coin I covered in scan spray. For size reference: the coin is roughly 21mm in diameter. The Rockit is more of a consumer focused device (priced at 2k€ so just inside consumer/enthusiast pricing) and the Rigil priced at 6k€ is a proper commercial device (you may still argue about this because you can easily spend 50k for a handheld scanner from other brands or even Shining3d).

Scanning

Scan settings and scanning steps are similar for the used scanners, deviations due to technical limitations are explicitly noted (e.g. limits due to max. resolution).

Scan Preparation

  • Both scanners freshly calibrated after letting them warm up a few minutes
  • Gold coin placed on a bed of markers and printed marker geometries
  • scan spray is applied in a thin coat to reduce reflectiveness whilst retaining detail
  • for scans of front and back a small amount of bluetack is used (try not to stretch it to prevent elastic deformation and creep, modeling clay also can work wonders)
  • for scan standing up it is fixed with helping hands (Onmifixo if you're interested, got it for soldering but also works as a holder for smaller parts)

Scan Process

  • 3 scans: front, back and on the side for alignment of front and back
  • 0.05mm target resolution
  • Wireless PC connection used (Rockit 90FPS, Rigil 120FPS)
  • mixture of cross-lines and parallel-lines (started with cross-lines for the bulk and then switched to parallel for sides and additional data capture)
  • all scans until target quality is reached

Post-Processing

Processing settings and steps are kept as similar as possible, deviations are explicitly noted (e.g. processing steps not supported for one scanner).

  • point cloud generation when finishing scans (no option to adjust any settings)
  • alignment front and back scan with side scan as alignment helper
  • removing side scan from project due to rougher quality than front and back
  • meshing with recommended settings
  • Integrated aligned tool in Exscan Rigil/Exstar Hub to orient scan to coordinate system

Results

Scan experience and processing was actually quite similar, workflows for both scanners are practically identical. Rigil is good bit faster while scanning (50laser lines at 120FPS vs 38 lines at 90FPS), otherwise similar.
Results are to some degree similar as with the first test of the 50ct coin but due to the scan spray usage the difference isn't as big. On both scans the embossing is recognizable but the Rigil is sharper and with less noise. Deviation between the scans is shown in the last picture: Everything green is within 0.025mm tolerance (or 1/1000 in for imperial units).

Accuracy of the Revopoint POP 4 Tested

Link to the video: Also created a video on my YouTube about this but I think just the slides is enough. If interested you can still watch it of course

One of the first things I did with the POP4 was testing the accuracy, this test is still done with the Micrometer but a ball plate is on the way so be relieved. Will redo the tests with the ball plate when it arrives but wanted to get the test out before the Kickstarter ends. Video shows the whole process and for those asking: the Micrometer was calibrated before each test.

TLDR of the results (for marker tracking)

  • Nominal: 124,984mm +/- 0.01mm
  • Mean: 124,993 (6 measurements)
  • ∆mean: 0,009
  • St.Dev: 0.01

Bronze Statue of Old Man - Creality Sermoon P1 IR mode

This bronze statue is life sized (roughly 1,8m tall without base) and I just noticed it standing by my usual commute.

Scanning

Scanning was done with the Sermoon P1 in large IR mode with geometry tracking. The P1 was used standalone outdoors in bright sunlight, this caused initally some problems with auto exposure due to the very bright sky but with manual exposure corrected to the statue itself it worked very good.
With initial firmware versions the P1 only could do 5-7fps in IR mode standalone, with the latest version it reaches a stable 19-20FPS. With the increased speed the scan only took roughly 5min without any tracking problems.

Post-Processing

For post processing I first transferred the scan data from the P1 to my workstation. You can either do it by cable where a nice import menu opens or over WiFi where you select the project on the scanner, join the hotspot of the scanner with your PC and send it to the PC (option I chose, simply less cables and quite fast with up to 120MB/s from testing). I then fused the scan at 1.5mm with 50% noise removal to retain detail (default noise removal tends to be a bit high) and meshed it with default settings. After meshing I performed color mapping. In postprocessing I decreased the contrast of the texture a bit (very harsh sunlight from the front).

Result

Best have a look at Sketchfab, quite content with the result. Finally IR mode is a joy to use standalone, hope they will bring hybrid geometry and texture tracking at some point.

Sketchfab

Sketchfab is like printables for 3d scans with a nice integrated viewer in browser and you can also download the scan, just look at the scan yourself.
Reddit sadly blocks the short links to Sketchfab, you have to search for the title instead: "Bronze Statue of Old Man - Creality Sermoon P1"

PC Specs

Since a lot of people ask for it:

  • AMD Ryzen 7950X
  • 128GBGB DDR5 RAM
  • RTX 5070Ti Desktop
  • A few TB of NVME storage with PCIe Gen4 interface

Revopoint POP 4: Unboxing and first Tests

My Pop4 arrived for testing (provided by Revopoint but no influence to my opinion of the scanner). In this video I do a first unboxing and initial testing of the different scan modes, performance wired and wireless as well as looking a bit closer at the scanner itself and also the "AI" segmentation for scanning. Short spoiler: The segmentation works better than I expected and is actually quite useful, still have to test with more demanding subjects but with my skull as target it worked excellent. Scan performance is very good from the first tests, punches above it's price (currently ~700$ on Kickstarter including shipping and taxes, regular price will be roughly 900$) and finally is an option by Revopoint that combines both laser scanning and IR scanning in one scanner.
As soon as the mobile app is available I will posts tests of supported scan modes and performance of the mobile scanning, may be quite a compelling option if it works well. Of course I will also do accuracy testing and scanning of my default geometries so you can get an idea of the scanners performance.

I also psted some pictures of the scanner, accessories and comparison to the MetroY Pro for the interested.
