Camera Calibration Settings

This widget allows specifying parameters for camera calibration.

The checkbox Fix principal point specifies whether the principal point should remain unchanged during the calibration (stays in the image center if no initial intrinsics provided).

Fix aspect ratio - the ratio fx/fy stays the same as in the initial intrinsics.

Fix radial k1, Fix radial k2, Fix radial k3 - the corresponding radial distortion coefficient is not changed during the calibration.

Zero tangential distortion - tangential distortion coefficients (p1,p2) are set to zeros and stay zero.

Recalibrate with inliers specifies whether calibration should be re-run with images that have per-frame MRE smaller than the one specified in Max reprojection error.

Min detections specifies the minimum number of detected points per image.
