Calibrate camera - reprojection error
Hi I'm trying to calibrate a camera for undistort and pose estimation. What is acceptable value of reprojection error? The best value I got is around 3 for 30 source images. When I use more images, like 70 or 100, the reprojection error is more than twice bigger and pose estimation is very inaccurate.
Acceptable value should be less than 1 px for the reprojection error. You should try with less images like 20 but with different orientations. Example of calibration images here with "left.jpg" images.
Depends also if you have a strong distorsion or not.
