Looking at your images, I notice that they are quite distorted. It looks as if you had actually taken them through a window, and probably a not very plane one. With starting material like that, the control point generators are having a very hard time. If you have to take aerial photogaphs through a window, make sure you always hold the camera as close to the pane as possible and set the camera to infinite distance (pocket cameras often have a little 'mountains' symbol for that). If there is a pane, though, and you try to photograph downwards, you hit the pane at a shallow angle, creating bad distortions. Ideally you'd have the camera pointing straight down without a pane in between; I realize this may not be feasible, but with a pane in between your images become very hard to process at all. What I don't understand about your images is why they are all different sizes. This confuses the optimizer, since it tries to create different fields of view etc. for every image. Best to leave them as you get them out of the camera - if there are any artifacts in them (plane's wings etc.) it's easy to exclude them using the masking feature. If at all possible, all the images should be taken with similar yaw and pitch, to allow initial optimization of X,Y and Z inside the strips with the pitch and yaw set to estimated figures. So if you can, just mount the camera and leave it like that. If you have a camera that you can remote-control, you can mount it on the plane pointing straight down and control it from inside the plane. Try using short exposure times (if you can't set the exposure time, use a high ISO setting) to minimize distortions due to vibrations. Finally, you should take the images in regular time intervals and try to create sufficient overlap between them, I found your images don't always overlap sufficiently. > As you can see, there are serval problems with the highway.

With a lot af handwork you'll approach a solution, but it will be far from optimal. I recommend you do another take. with regards Kay -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
