Handheld SLAM Laser Scanner Alignment
« on: June 06, 2024, 03:52:54 PM »
I have a handheld lidar scanner that I have scanned the interior of a building with. This scanner has three RGB cameras on it that I'm trying to bring in along with the point cloud. The images import as a multi-camera rig and align on their own pretty good. I have then added 5 markers in the images with the same placed markers added to the point cloud. They still will not align properly. My trajectory path and the point cloud lines up perfectly so you'd think Metashape could use this as a starting point for the images too. I've used the update button in the reference tab like I have read and the documents but it does not seem to do anything. Any help is greatly appreciated, I would like to recolorize the point cloud and create a texture for the mesh using these images.

When adding markers, add them to the point cloud first and then pick and assign the same marker locations in the images. The images should then move into the correct position when you click the update reference button if you have enough markers.
