Abstract

The invention relates to an automobile instrument pointer positioning method based on vision. The method comprises the steps: obtaining an image of a workpiece tray for placing a pointer by a camera head, and obtaining the coordinate position of the pointer from the image by a computer; transmitting the information of coordinate position of the pointer to an action actuator, and driving a pointer taking adsorption head to the pointer position by the action actuator; adsorbing the pointer onto the pointer taking adsorption head by negative pressure generated by a pressure extracting machine, and then driving the pointer taking adsorption head adsorbing the pointer to move to a pointer mounting device by the action actuator. A system for realizing the method completes the pointer grabbing work through the pressure extracting machine, a breather pipe, a fixed tube, the pointer taking adsorption head, a fixed plate and the camera head, and solves the problem that the pointer is put into a specified feed trough in advance by people and then a motion control system grabs the pointer on the fixed position, thereby shortening the operation time, improving the working efficiency, avoiding manual putting, and reducing the labor cost.

Description

technical field [0001] The invention relates to the field of physics, in particular to the instrument pointer positioning technology, in particular to a vision-based automobile instrument pointer positioning method and system. Background technique [0002] The instrument pointer refers to the parts used to indicate data on the instrument. The function of the pointer is to indicate the complex data structure in a more objective and direct way. It is one of the main performances of instruments and meters. The design and structure of the pointer is conducive to improving the accuracy of instruments and meters and reducing errors. [0003] In the production process of automobile instrument, it is necessary to install the pointer processed in the previous process into the instrument. In this process, it is necessary to manually place the pointer in the designated trough, and then the motion control system will go to a fixed position to complete the work of grabbing the pointer. ...
