I would expect aerial images of mountains would be impossible to stitch correctly because of parallax problems. But if the surface photographed is relatively flat (vs. the altitude from which it is photographed) there should be a correct way to stitch. Someone who understands Hugin's stitching better than I do my correct me on this, but so far as I understand: When the camera position is moved between images, you need some model of the target surface in order to remap the images. Hugin can model the target as a flat surface at an arbitrary angle relative to its viewing angle from the camera position. Given a decent collection of control points, optimization can find the position of the camera and the viewing angle of the camera (yaw, pitch and roll) AND also compute the angle of the target surface. If the altitude of the camera is great enough relative to the surface texture, that computation should remove parallax issues. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
