The robot deburring machine uses machine vision to detect the hole position, and discusses the calculation method of the internal and external parameters of the camera in detail, and transforms the object image according to the calibration to transform the coordinates of the target point in the camera coordinate system to the In the coordinate system of the burr robot, the three-dimensional space coordinates of the space target point are obtained, and then the two-step method is used to guide and control the deburring robot.
