Laser Scans Have Non-Unit Scale
« on: October 12, 2024, 06:27:04 PM »
So, I have created a point cloud from drone RTK imagery, and the accuracy is pretty good with point cloud reconstruction.  When I try to set it as a laser scan so I can align with another scan, I get a "Chunk or some laser scans have a non-unit scale which will be reset" error


2024-10-12 08:23:44 chunk scale: 9.70177, point cloud 0 [mavic3e_2024-06-22] scale: 1, total scale: 9.70177 = 9.70177 * 1

Ideas?

Hello Jeff,

It is not recommended to switch photogrammetric point clouds to laser scans. But as a workaround you can export scaled photogrammetric dense point cloud and then import it back as laser scan. Let me know, if it works without the scale warning.
