Hello Folks, I am using boxturtle to do stereo calibration. I have been running the cameracalibrator.py node with no trouble up until the point where it needs to calibrate. When I hit the green calibrate button, and it outputs this error message: epipolar error: 0.740361764685 OpenCV Error: Assertion failed (src.type() == dst.type() && dst.size() == mapx.size()) in cvRemap, file /home/asher/ros/stacks/vision_opencv/opencv2/build/opencv-svn/src/cv/cvimgwarp.cpp, line 3083 Exception in thread Thread-9: Traceback (most recent call last): File "/usr/lib/python2.6/threading.py", line 525, in __bootstrap_inner self.run() File "./cameracalibrator.py", line 59, in run self.function(m) File "./cameracalibrator.py", line 233, in handle_stereo lscrib = self.c.lremap(lrgb) File "/home/asher/ros/stacks/image_pipeline/camera_calibration/src/camera_calibration/calibrator.py", line 407, in lremap cv.Remap(src, r, self.lmapx, self.lmapy) error: src.type() == dst.type() && dst.size() == mapx.size() I am a bit flummoxed by the error as the arguments to lremap all seem to be OK. Is there some way I could be making a mistake in setting up the calibrator? Have other people had this problem with the current revision of boxturtle? Thank you for the help and guidance, Adam Stambler
