GoPro -> 3D GCP -> Jagged Triangle Mesh

[Rosana_Lin]

Hi Jackson,

Thank you for sharing more about your project.
Based on the quality report, the median of keypoints per image is the issue.

After cross-checking the number of ATPs per pixel, I could see there are some black dots. Black indicates that, on average, 0 ATPs have been extracted at
the pixel location. So the more black dots we have, it indicates there is a high chance the issue could be related to overlap.

Have you tried adding some MTPs and then reoptimize? If not, I recommend adding some MTPs. Menu Process > Reoptimize

Using a GoPro is quite tricky and can be very challenging. If anyone else or GoPro users have thoughts or experience with this sort of workflow feel free to provide your additional advice or experiences.
I also found this thread that increasing the overlap sometimes could greatly help with the issue.

GoPro on a pole?

Hi Nicolas, I was able to get the images to calibrate using the following Step 1 processing options.  _ Keypoint image scale = Full_ _ Matching Image Pairs = Free flight or terrestrial_ _ Calibration Method = Alternative_ _ Internal parameters optimization = All Prior_  Despite being able to calibrate there is a substantial amount of noise generated by the sky. You can use the carve annotation tool to help reduce the noise before running step 2. Also, I would recommend creating a few MTPs …

Best regards,
