Embodiment Construction
[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] The embodiment of the present invention discloses a three-dimensional vision precise guidance and positioning method for automatic loading of automobile intelligent manufacturing. The visual detection algorithm calculates the position and angle deviation of the part in the fixed coordinate system, so that the robot can automatically correct the track and grab the material.
[0029] The visual detection algorithm, the visual detection algorithm is to solve the position and attitude of the object relative to the camera at the time of shooting through the n image points obtained by perspective projection. Remember the camera coordinate system O c -x c the y c z c The orientation of the object coordinate system O-xyz is [R,...

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.
