Hello ugo,

During the Align Photos stage at first PhotoScan searches for the feature points on the individual photos. The max number of feature points per photo is limited by Key Point Limit parameter (in Align Photos dialog).
Then individual features are matched across the images, if any feature points are considered to be the same, they are turned into tie point (matching point). Every tie point may have two or more projections, depending on the number of images it appears.
Tie point limit parameter defines the upper threshold for the tie points that can be present on the individual photos.
