## Scanning
The scan was created in large IR-mode with automatic exposure and geometry tracking. I started from the front and slowly moved around the part while keeping an eye on having enough overlap for tracking (rotating the scanner to reach in to the crevices works quite well to circumvent obstructions due to limited line of sight). While scanning the framereate was roughly 10 FPS with some highs to 15 and lows to 6 FPS (NIR mode still needs an update I guess, currently no marker scannign supported).

## Post-Processing
For post processing I fused the scan at 1mm and and meshed it it with default settings. For alignment I used the untegrated tooling in Creality Scan (basically rotating the part until alignment is right). The figurine then was printed from PLA to create a minature version.

**Car: **Opel Corsa 2023 Facelift

## Scanning
The scan was created in large IR-mode with automatic exposure and geometry tracking. I didn't capture any texture but still enabled the texture fill light to have a better feeling of what I scanned (was already dark outside). The whole scan took roughly 2:30 min and was finished when all parts reached the quality indiator (would be nice if the resolution in IR mode could be preset to have the qualitiy indicator represent this setting like in laser mode).

## Post-Processing
After scanning I transferred the scan project wired to my PC and only needed to press one button (fuse at default settings). Creality Scan already produces a mesh when performing the fusion so no additional meshing needed. The mesh was then exported and I used Quicksurface to reduce and orient the scan to the coordinate system.

Real gun scanned with Creality Sermoon P1.
Version is HS Product SF19 also known in US as Springfield XDM, 9mm version.

Springfield XDM - HS Product SF19 (3D scan)

## Scanning
Scanning was done in standalone mode at highest resolution (0.2mm, PC connected can be higher) and until target quality was reached. I placed the casting on bed of marker cards and geometries so I can also capture the sides of the casting. The scan itself was performed with all three laser modes taking roughly 5min for scanning. No scan spray was used for scanning.

## Post-Processing
I imported the scan project to my PC over USB and then fused the scan at default settings (0.2mm). Afterwards I used Quicksurface to align the scan to the coordinate system.

## Scanning
The scans were captured with wireless connection to my workstation to capture the data faster (~80FPS over WiFi).  
For the laser scan 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 0.1mm and exposure was adjusted so the white print wasn't overexposed. For laser mode I used a combination of cross, parallel and single line mode, changing them can be done by double pressing the scan start button on the scanner.   

## Post-Processing
For both scans processing was done using the recommended settings within CrealityScan. This is basically only Fusion since it already generates a mesh at this step which can directly be exported.  
After exporting the meshes I used Quicksurface to align the meshes to the coordinate system and each other.

## Scanning
Scanning was done in standalone mode at highest resolution (0.2mm, PC connected can be up to 0.1mm) and until target quality was reached. I placed the statue bed of marker cards and geometries so I can also capture the sides of the statue. The scan itself was performed with all three laser modes taking roughly 5min for scanning. No scan spray was used for scanning. Same approach was repeated for the back side of the statue.

## Post-Processing
I imported the scan project to my PC over USB and then fused the scan at default settings (0.2mm) and aligned front and back scan. Afterwards I used Quicksurface to align the scan to the coordinate system.

For this part I also did a quick reverse engineering of the negative for later milling. I simply used auto surfacing in Quicksurface toleranced to 0.1mm (everything in green within 0.1mm).

Wax Casting of Church - Creality Sermoon P1

## Scanning
The scans were captured with wireless connection to my workstation to capture the data faster (~80FPS over WiFi).  
IR mode had to be done in feature tracking since marker tracking is not yet supported by the software. For this I used the normal size which provides better tracking and is the mode I use most often when using IR mode (same mode was selected with the Rigil in IR mode).

## Post-Processing
For both scans processing was done using the recommended settings within CrealityScan. This is basically only Fusion since it already generates a mesh at this step which can directly be exported.  
After exporting the meshes I used Quicksurface to align the meshes to the coordinate system and each other. The laser scans had to be reduced to allow upload to Sketchfab (just under 4M triangles will result in a 100MB ply when exporting from Quicksurface).

Scan Bench - Creality Sermoon P1 IR Normal

## Scanning
The scan was created in IR-mode with automatic exposure and geometry tracking. I created two scans: one of the whole tombstone in large scan mode and one detailed one of the head in normal scan mode. I started from the front and slowly moved around the part while keeping an eye on having enough overlap for tracking (rotating the scanner to reach in to the crevices works quite well to circumvent obstructions due to limited line of sight). While scanning the framerate was roughly 10 FPS with some highs to 15 and lows to 6 FPS (NIR mode still needs an update I guess, currently no marker scanning supported).

## Post-Processing
For post processing I first transferred the scan data from the P1 to my workstation. I then fused the whole tombstone scan at 1mm and the high detail at 0.5mm. Fusion already creates a mesh so no need to mesh a second time (only needed when merging multiple scans or when you need texture mapping). For alignment and cleanup of the base I used Quicksurface.

Father and Child Tombstone Detail - Sermoon P1

## Scanning
The scan was created in large IR-mode with automatic exposure and geometry tracking. P1 now can to a steady 19-20fps in standalone mode so tracking was no problem. I simply scanned segments of the cone and then moved to the next segment (roughly thirds), circling around can cause problems with tracking. Impressed tracking wasn't lost at the base with relatively low amount of unique geometry.

## Post-Processing
I then fused the scan at 1mm 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 and did a rough alignment withing Creality Scan (tip: right click gives you the option to enable orthographic view, makes alignment much easier).

Giant Ice Cone - Creality Sermoon P1

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.

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

Father and Child Tombstone - 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))

Skull - Markerless Laser Creality Sermoon P1

## 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
I then fused the scan at 1mm 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).

Bronze Statue of Old Man - Creality Sermoon P1

## Scanning
I simply chose IR mode with the large setting, automatic exposure and geometry tracking. One setting that initially confused me was the base removal. It is turned on by default and therefore the floor wasn't scanned at all, after disabling the floor is also captured. Additionally when changing scan settings in the UI you must press "Apply" for the changes to come in effect. After starting scanning I just slowly moved around the sofa always using the folds and creases of the pillows as geometry to track. The IR performance really reminds me of the Sermoon S1 (P1 in standalone reaches somewhere between 10 to 15FPS, 30 FPS connected to a PC (wired and wireless) as the S1 does). Hopefully the IR mode can still be made faster in standalone mode but I guess this is always the case for every scanner and every mode (laser scanning already reaches 60 FPS). The whole scan took maybe 4 to 5 min.
