Hi All,

I'm working on a 3d reconstruction of a scene, I took 13 pairs of calibration images using a checkerboard pattern, When I calibratie the camera's one by one I get a reproduction errors < 0.4 pixel, how ever wehen usig the steroe calibration app I get a reprojection error of > 200 pixel and some very very weird deformed images. I noiced that the app defined the origin of the x-y system radomly, when I select only image pais having the same corenr chosesn for origin the reproejction error goes down to 20 pixel (still far to high). Has anybodey suggestions whtacould be wrong? If you need more infor, please let me know.

kind regards
