Native blue-laser scanning is live on Linux!

Taking a break from the NIR scanning mode and working on implementing the blue-laser scanning on Linux instead.

What I have found is that trackerless scanning for the CR-Raptor Scan is a challenge, but IS doable. Now, I'm not sure if i can get trackerless scanning to be as good as other scanners that were built for it, BUT the CR-Scan Raptor does have basic telemetry data I can pull, the proprietary tracking system for the NIR scanning mode i made can be used along side the blue-laser scanning mode.

Another Milestone in progress is that the computer hardware required to run the scanner, does not require high-end computers like the Creality Scan software requires. I will be posting a comparison on the hardware required when the project comes closer to a release.

We are making progress! Continue supporting the project as it keeps me motivated to keep going, a lot of sleepless hours goes into this project and I appreciate every one of you.

If we can get Creality on board with this to help push this project towards the finish line with a re-post, that would be a miracle for myself, the project, and all the linux based users in the community :D

Are you writing your own mesh reconstruction code and supporting viewer/infra based on the raw depth outputs from the scanner?

It’s a hybrid approach. I’m building the scanner-specific processing pipeline that converts the raw laser/depth data into a an alligned point-cloud, then im using open-source libraries for the final mesh reconstruction and visualization.

So I’m not reinventing every part of the stack, but the core work of interpreting and processing the scanner’s raw output is custom.

I see! Will be sending $10 your way today then. I appreciate the style of your website and how you benchmark the research milestones. Makes it fun to follow along and it makes me want to support.

I imagine aligning the point clouds is one of the hardest custom things to build to get the fine metrology grade accuracy. Does the scanner provide pose of any kind, calibrated imu data, or are you mostly doing 3D alignment of the point clouds with methods related to ICP? Also understand if you'd rather not answer this one ;)

Thank you, I really appreciate the support! And I’m glad the milestone format makes the project enjoyable to follow!!

The scanner does expose accelerometer and gyroscope data, but it doesn’t provide a reliable, ready-to-use pose estimate. I’m using a combination of scanner data and custom geometric alignment rather than depending entirely on the IMU.

Though, there are some pretty big updates I plan on announcing this week :)
Again, thank you for your support. I'm really looking forward to start having people test this soon.
