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.

Auto select images - if selected a subset of images will be automatically selected, instead of using all images.

Max reprojection error - specifies maximum reprojection error for inliers to use in recalibration when Recalibrate with inliers is enabled.

Min detections - minimum number of detected points per image required to use image for calibration.

Max selected images - maximum number of images to select when Auto select images is enabled.
