Good afternoon. I’m new to drone photogrammetry, using a Skydio 2. I’m trying to map a worksite’s topography for drainage. The drone’s output is a series of geolocated images.

After initialization, the cameras in my project seem to be calibrated onto a tilted plane. The output seems dimensionally correct with respect to said plane. This tilt carries through to the point cloud and mesh. From what I read, I believe the solution is to enter more 3D GCPs, but I’d like to know if there is a way to manually correct the tilt somehow or if I’m missing something basic in my setup.

One of my pictures is in the link below:

Hi Ben,  
Can you attach your PDF quality report to this posting? We’ll take a look to see what could be going on.

Hi Ben,  
I took a quick look at your quality report. I think you should reprocess, but this time use the 3D Maps template. This is set up for projects like yours. See how well it processes and let us know. If there are issues then upload your latest quality report.
