Thank you Bruno! This is exactly what I'm looking for, and you actually correctly mended the two pictures :) The trunk build... I'm gonna take a leap and guess there are no windows binaries for that? Oh well.. here come cygwin chaos :P I'll try to get it running in a few days, when I have time again.
Pell: Thanks for the advice. I believe I can't set the aperture settings of my Canon IXUS 90 IS, that's too bad. I only have control over ISO, flash, and exposure... I've cleaned the lens, maybe that helps image quality a little. Actually, the fuzzyness may be related to the removal of the barrel distortion? I used PTlens to do that, with the preset settings for my camera. It's not entirely correct, but pretty close. Actually standing in one place on the roof is difficult, since these are just 2 examples, I want to join pictures of the entire rooftop, including the place I would be standing :P The merge you made looks reasonable, but is not entirely correct. The pictures have more overlap than the merge you made. Here's a screenshot with some manual control points for reference: http://hugin-ptx.googlegroups.com/web/control%20points.jpg I'll try to use/edit your script soon, when I have some time. Carl: Sorry for the confusion. The corners shown in the picture aren't actually the same corners. It's the left and the right corner, basically. I agree that this isn't really panorama stitching, but I was hoping the same concepts would work for what I was trying. Rotating only around the NPP is not always an option, since I want the entire roof, including the bit beneath the NPP. I did try to manually choose control points, I don't need autodetection really, I agree that that's nearly impossible. However, the output I get is some really weird spikey graphics in the upper right, which look the way graphics card glitches would look. May be user error though. Actually the loss of detail I mentioned is unrelated to the stitching in sketchup. It's just some very low quality resampling it automatically does when merging 2 textures on faces which are side by side. Habi: There is some overlap, you just have to skew the pictures greatly to get them to align them. See Bruno's merge: http://www.flickr.com/photos/36383...@n00/4529655520/ Taking the pictures panorama-style is not going to work, because I want to have a picture which I can use as a texture on a 3d model of a building. For example: http://hugin-ptx.googlegroups.com/web/sketchup.jpg (You can see that one sucks pretty bad. Low quality, badly aligned, differences in lighting, etc..) Essentially, I want to convert a number of these pictures into a top- down view. Thanks for all the replies!
