General / Re: Camera calibration for UAV

« on: April 08, 2019, 09:20:43 PM »

Is it possible to over optimize the camera calibration?

I flew a small test project with a Phantom 4 RTK with about 100 photos at 400 foot elevation.  There are 6 high accuracy GCP's.  My original plan was to use the GCP's only as check points, but residuals were a foot off.  I decided to optimize the camera calibration and now the GCP's check within 0.01 foot, and camera coordinates show about 0.02 foot, which seem too good to be true.

Is there a danger that the camera calibration simply fit itself to the data?

Is there any way to view the Survey Statistics in a spreadsheet view?  The current graphic view is nice, but some numbers would be helpful like those of the competitor, especially for those of us trying to achieve greatest accuracy.

This would be a nice feature!

I need an additional option for the base to be from a TIN created from the perimeter polygon outline.    It is the only way to get an accurate pile volume.  Without this I'll need to export to other software for volume calculations.
