On plane-based camera calibration
WebTo achieve fast calibration of line structured light sensor, a geometric calibration approach based on single circular calibration target is proposed. The proposed method uses the circular points to establish linear equations, and according to the angle constraint, the camera intrinsic parameters can be calculated through optimization. Then, the light … Webthe camera, either partially or fully, depending on the number of calibration planes, the number of images, the number of intrinsic parameters to be computed and on …
