Abstract
Disclosed are methods adapted to calibrate a robot gripper to a camera. The method includes providing a robot with a coupled moveable gripper, providing one or more cameras, providing a target scene having one or more fixed target points, moving the gripper and capturing images of the target scene at two or more imaging locations, recording positions in the gripper coordinate system for each of the imaging locations, recording images in a camera coordinate system, and processing the images and positions to determine a gripper-to-camera transformation between the gripper coordinate system and the camera coordinate system. The transformation may be accomplished by nonlinear least-squares minimization, such as the Levenberg-Marquardt method. Robot calibration apparatus for carrying out the method are disclosed, as are other aspects.
