WebCamera calibration in StereoMorph is based on a checkerboard pattern. The checkerboard provides a sampling of points in a plane that can easily be detected automatically. This saves the user time by not having to manually identify calibration points. WebUsually, calibration should be performed on at least 6 observations (images) of a calibration target. If a higher order camera or distortion model is used, more observations are beneficial. Consider using uniquely coded targets such as CharuCo boards.
