Error 999999 Failed to execute computecameramodel help please!

Hi Everyone, New user to Arcgis Pro and having inconsistent results trying to produce orthomosaics.

The error code is 999999 and the error message is failed to execute "ComputeCameraModel".

I tried working with a smaller sample of images. The camera used is the Mapir Survey 3N and I have populated the camera parameters with the correct Focal length, Pixel size and columns and rows.

Here is a copy of the logs.

Thank you Guenter! I have posted all the info I could find on the camera and regarding the input data do you need the whole image set? I uploaded one image with my original post so let me know. I really appreciate you taking the time to help!

Hi, I've had an engineer look at your notes, and I think the exposure is the problem.

Our camera database does not contain this camera, so it will not automatically recognize the MapIR, but it looks like you *do* have the workspace set up correctly. Unfortunately, the image you sent is extremely dark - the brightest pixel in the image seems to be DN value of 13. Are all of the images this dark? Do you have another sample dataset with a more normal exposure?

If the software can't find any tie points between images, it will remove them as "unsolvable".

Thank you Cody! I will look at the exposure settings. Mapir state not to adjust the default exposure settings on the camera. I'll test and let you know.

Solved! Thank you everyone. Its was the exposure settings as you stated. They were set too low by default on the Mapir camera and as you mentioned this stopped the software from finding tie points between the images. Much appreciated.
