Reprojection error is the core metric for evaluating camera calibration quality; it is obtained by reprojecting 3D calibration board corner points back onto the image plane, comparing the projected positions with the actually detected positions in pixel distance, and taking the average.

UnverifiedThe industry-recognized standard for high-quality reprojection error in camera calibration is below 0.3–0.5 pixels.77% similarUnverifiedAccurate estimation of distortion coefficients relies particularly on data from the corner regions of the image; during calibration shots, the calibration board must cover the center, four corners, and edges of the image, and must include large-tilt poses approaching 45°.73% similar
