SYSTEM AND METHOD FOR OPTICAL AXIS CALIBRATION

A method for calibrating an optical axis of a camera mounted to a movable structure is disclosed. The method includes: for each of two or more standoff distances for the camera: capture, using the camera, image data of a target marker while the movable structure is undergoing rotation about a fixed...

Zusammenfassung:	A method for calibrating an optical axis of a camera mounted to a movable structure is disclosed. The method includes: for each of two or more standoff distances for the camera: capture, using the camera, image data of a target marker while the movable structure is undergoing rotation about a fixed axis, the target marker being a grid of squares each including unique detectable features; determine a respective center of rotation based on the captured image data; determine a first axis which goes through the centers of rotation; and determine a transform between the first axis and a second axis through the center of output image of the camera.
