I see, that makes sense then. The material that is being photographed moves around ever so slightly, and because one pixel is about 3.76 μm I found that I had to also adjust for the roll and yaw. Would there be a way to tell it to not change/optimise the yaw by more than (say) a few degrees? That could prove to be quite helpful. No, there are no such constraints possible. Maybe drop the optimization of y0 and call pano_modify --center after the optimization to bring the pano back to the center. > PS: Hugin has also possibilities to handle such use cases. > First assign rough image positions according to your layout.

So no need to reinvent the wheel twice. The reasons I made a custom control pointer finder is that (1) cpfind wouldn't find control points in cases where I really expected it to find control points (also with different sieve1/sieve2 sizes) and You are using very high number for sieve1width/height. This could also slow down the processing. (2) because cpfind is relatively slow for the images (151 megapixel times 16) that I am working with, even if things are prealigned (as I understand it). After automatically stitching 10000+ images I'm very close to a 100% success rate, but I couldn't quite get there with just cpfind. I didn't figure out how to use pto_template make a template with pre-aligned images. Is there any documentation available on how to do this? Take a project file of a finished pano with the same layout. Then use this project file as template for another project file with the same layout (and same number of images). And then use cpfind --prealigned on this project.
