Orthophoto of UltracamX Data Problems
« on: May 23, 2014, 10:38:31 PM »
Im testing to make orthophotos with agisoft photoscan pro of UltracamX Images 10 cm GSD.
The result of the dense 3D pointcloud is realy great but the orthophoto in different areas is bad.

1. Moving Objects like Cars and Trucks
Here i get a orthophoto with mixed pixels from cars and street. Is there a workflow to get only the street or the complete car ?

2. Power Pole
Here i get a orthophoto with blurred pixels at the power poles, of course of the not dense enough of 3d pointloud of the power pole. If i delete the points of the power pole i get the problem because of the different views to the power pole and so i get the same problems like moving objects, i get mixed pixels

For solving the problems it was great to define polygons to take only a selected image for these areas. Or make the orthophoto mosaiking by defining cutlines or areas like in other classic photogrammetric software, of course i get then only a normal orthophoto and not a trueorthophoto.
