Methods and systems for performing automatic camera calibration for robot control

摘要

PROBLEM TO BE SOLVED: To present a robot control system and an automatic camera calibration method. A robot control system includes a control circuit configured to obtain all angular positions of a virtual cube that fits within a camera field of view, and to obtain a plurality of positions distributed on or through the virtual cube. .. The control circuit controls the robot arm to move the calibration pattern to multiple positions, receives multiple calibration images corresponding to multiple positions, and estimates each of the unique camera parameters based on the multiple calibration images. It is further configured to find the value and to find the estimated value of the transformation function that describes the relationship between the camera coordinate system and the world coordinate system. The control circuit is further configured to control the placement of the robot arm based on the estimated value of the conversion function. [Selection diagram] Fig. 4
