Setting capture distance doesn't find the matched image pairs

[JyunPingJhan]

Hi

I have images that have inital pitch angle between 20-25 degrees, where roll angle is approximate 0 and yaw amgle is obtained from GPS info.

During image matching stage, I can find correct image pairs if  reference preselection is unchceked. I understand this setting will seek matches between all possible image pairs, but really time consuming.

However, when I used source in reference preselection, while rotation angles and capture distance are also given, it cannot find matches on above sucessful matched pairs.

Attatched show the significant differences, I am wondering are there something wrong in my setting. Otherwise, I have to manually add markers to correct the misalignment.

Thanks

I've found that when using more than 100 images it fails to find matches on overlapping images, while fewer images do. Can you help me to check this phenomena?

Hello JyunPingJhan,

Can you please share the sample dataset that can be used to reproduce the problem to support@agisoft.com? Also please specify the Capture Distance value used and provide CSV file with the coordinate information and rotation angles.
