Camera Calibration / Point cloud / Ortho are skewed/tilted (no GCPs)
« on: May 12, 2020, 01:11:26 PM »
Hi folks,
I gonna be straight up: Its my first try with Metashape, but i spend a couple hours already trying to fix this bug and searching for solutions. So the answer to this might be obvious... I have photos of a building site shot with an UAV to generate an orthohoto. But after aligning the photos and every othger step after, the photos are tilted and not "nadir" as they were shot. As a result the projected point cloud is also tilted but worse, also skewed.... which leads to othophotos where i can see the wall of a house etc... I think the problem is in the calibration of the camera, but i couldnt find the solution...
I the exact same problem already with pix4D with this project, but there is an option where you can prioritise internal camera parameters, which fixes this problem. I shot the photos with the DJI Mavic 2 Pro. If anyone could help me out, this would be great! been struggeling with this for days...
Cheers
