I am trying to run the camera_calibration to calibrate a simple custom setup stereo pair.  I am using the uvc_stereo package to publish the raw camera images.<br><br>I get through the calibration (using a 5x4 checkerboard at the moment) after a minute of moving the checkerboard to the various positions around the image.  But once the calibrate button lights up and I hit it, it seems to still be looking for the checkerboard.  It also shows images which look to be zoomed in samples of the actual images, rather than what I would expect for poorly calibrated rectified images.  It also seems to be constantly recalculating the epipolar error (really high, usually over 10.0) whenever it finds the checkerboard after I have hit the calibrate button, or reporting the checkerboard not found if it&#39;s not in the image.<br>
<br>Based on the wiki page, I expected it to sample the images, then once the button was hit, to calculate and then print out or save the results.  Is this expected behavior, or am I doing something drastically wrong here?  Am I just getting a really bad set of images for calibration that is screwing up the calculations?<br>
<br>I am only running the image_raw publisher(s).  Do I need to also be running the stereo_image_proc while doing calibration?<br><br>Thanks,<br><br>Jeff Hyams<br>RE2, Inc.<br>
