Robot hand-eye calibration method based on laser range finding

The invention discloses a robot hand-eye calibration method based on laser range finding. According to the method, by calculating the coordinates of laser spots under a laser range finder coordinate system, the coordinates of the laser spots under a robot coordinate system are calculated by means of the mapping relation between the laser range finder coordinate system and the robot coordinate system; by capturing pictures of the laser spots on a calibration board through a camera, the coordinates of the laser spots under a pixel coordinate system are calculated, and therefore the mapping relation between the pixel coordinate system and the robot coordinate system is calculated; the mapping relation between a camera coordinate system and the pixel coordinate system is obtained by means of parameters of the camera; and then the mapping relation between the camera coordinate system and the robot coordinate system is calculated according to the spatial switching relation. The method is carried out by emitting the laser spots to the surface of an object through a laser range finder, coordinate information of measurement points is obtained without the need of making contact with the object, in this way, operating errors are reduced, operation is easier, precision is high, manual participation is not needed in a calibration process, and automation and intellectualization are achieved.

Robot hand and eye calibrating method based on scanner

The invention discloses a robot hand and eye calibrating method based on a scanner. The robot hand and eye calibrating method comprises the steps that a transformation matrix of an end tool coordinate system of a robot relative to a base coordinate system of the robot is established; a transformation matrix of a coordinate system of the scanner relative to the base coordinate system of the robot is established; and calibration of the positioning precision of the robot based on the scanner is completed by calculating the relation between the coordinate system of the scanner and the end tool coordinate system of the robot. By means of the robot hand and eye calibrating method based on the scanner, the calibration of the positioning precision of the robot based on the scanner is completed to calculate the fixed position relation of the scanner relative to the robot so that the scanner can then be used for scanning an end clamping tool of the robot to obtain the actual position of the end tool of the robot relative to the end coordinate system of the robot; errors generated due to inaccuracy of technical operation such as installation are eliminated so that the calibrated robot can precisely scan workpieces on different occasions, and the machining precision is improved.
