If you set the weight of a control point to a value W, the geometrical optimizer treats it like if there were instead W control points at the same position (if W in an integer). However W needs not to integer. If no weight is given, a weight of 1 is assumed.
If for some reason the stitching yields visible striking errors at a position, you could force the error to get smaller by increasing the weights of CPs near this position. However, the errors at other positions will increase more or less. If you unfortunately increase the weight of a CP that is bad positioned (on moving objects or due to not corrected errors from lens distortion) this will lead to much more visual defects at other positions. So you could e.g. set the weight set to 4 in order to make the error smaller at this position, but setting it to 100 could be problematic. I have a large panorama where I took the photos with a relative small angle of view (tele photo). On some CPs on the trunk of a tree I set the weight to 100, but on some photos are only small branches or leafs of trees, and these CP have weights of 1. On some photos I didn't have another choice but using CPs on clouds, and I set their weights smaller than 1, e.g. 0.1. gunter.ko...@gmail.com schrieb am Montag, 9.
