The invention discloses a hand-eye vision calibration method for a robot hole boring system, and the hand-eye vision calibration method comprises the steps of firstly calibrating an origin point of a coordinate system of a tool on an end effector of the robot, that is TCP, establishing a scene coordinate system in a shot plane, then shooting two points in the plane, using the TCP to contact the two points, further obtaining the relationship between an imaging coordinate system of a camera and the scene coordinate system and utilizing the relationship to calculate the position relationship of the TCP in the scene coordinate system. Finally, the position relationship between the TCP and the imaging coordinate system of the camera, that is the hand-eye relationship, is indirectly obtained by taking the scene coordinate system as an intermediate conversion coordinate system. The hand-eye vision calibration method ignores depth information of the camera in the hand-eye relationship and transforms the calibration process into the geometric relationship, the calibration process is simple, the calculation amount is small, an expensive three-coordinate measuring device is unnecessary, and the precision is higher, thereby having higher practical value and being capable of meeting the practical working needs of the robot hole boring system.
