I am using pix4D to process images from the drone WingtraOne. My main outputs are point clouds, DSM and orthophotos. I noticed some mistakes in the point cloud : when an area is under a dark shadow, the points can have mistakes in height up to some meters ; roads have often a thickness of several centimeters (more than expected) ; … I am assuming that this is the results of mismatching pixel in pictures, due to large contrasts or no matching for roads. Did you ever noticed this kind of issues ?
