“pairs” parameter in matchPhotos() function

[StevenShi]

When I use "pairs" argument in the matchPhotos() function and I define the pairs as list of camera pairs tuple which I want to match.
for example:

Code: [Select]

cameras = chunk.cameras
c_pairs = [(cameras[0],cameras[1]),(cameras[1],cameras[2]),(cameras[2],cameras[3])...]
chunk.matchPhotos(accuracy = PhotoScan.HighAccuracy,generic_preselection = True,reference_preselection = True,keypoint_limit=40000,tiepoint_limit = 4000,pairs=c_pairs)
But the result is that no any photos are aligned,why does it happen? Anything wrong about my operation?

Hello StevenShi,

After image matching you need to perform the camera alignment:

Code: [Select]

chunk.alignCameras()
