Importing Precise camera intrinsics and extrinsics

[Paulo]

Hello all,

I have a xml file containing calculated Exterior orientation (Extrinsic) and interior orientation (intrinsic) for a set of photos.

If I import this camera file to the chunk containing said photos, my idea was that we could then proceed to Dense cloud Generation as camera positions and camera parameters are known from imported xml.

Then, why is the program asking us to go over the sparse cloud generation (key point detection ,matching, etc...).?

Any insight will be appreciated!

Hello Paul,

It's necessary, since PhotoScan needs to understand which photos are overlapping and cannot do that without tie points between images.
