Three-dimensional vision accurate guiding and positioning method for automobile intelligent manufacturing automatic feeding

Abstract

The invention discloses a three-dimensional vision accurate guiding and positioning method for automobile intelligent manufacturing automatic feeding. A camera is used for conducting photographing and image collecting on a component, and the position and the angle deviation of the component under a fixed coordinate system are calculated through image processing and in combination with the vision detection algorithm; and a robot is used for transmitting the position and angle information, the track of the robot is corrected, the robot is guided to arrive at the correct work position, and accordingly the robot automatically corrects the track for workpiece grabbing and feeding. According to the three-dimensional vision accurate guiding and positioning method, the component grabbing precision is high, the precision can reach + / -0.5 mm, accurate positioning on a material box is not needed, and the cost and maintaining expense for accurately positioning the material box are omitted; and the later maintaining and adjusting technology is facilitated.
