Hand-eye calibration problem
WebNov 19, 2024 · An overview of hand-eye calibration. Due to the increase in the difficulty and diversity of tasks performed by robots, robot “hand-eye” collaborative operation has attracted widespread attention. This technology is widely used in aerospace, medical, automotive, and industrial fields. Recently, hand-eye calibration technology is … Webally mounted, a hand-eye calibration is necessary to align the camera coordinate system with the tilt-vergence link. The usual way to describe the hand-eye calibration is by means of homogeneous transformation matrices. We denote1 by X the transformation from camera to gripper, by Ai the transformation matrix from the camera to the world coordi-
