Abstract: In the PCB assembly process, it is difficult to quickly find the location of components by hand, which is an important factor affecting the efficiency of manual soldering. The component positioning system developed based on the coordinate transformation algorithm and image processing technology can realize the rapid query and positioning of the component number on the PCB. It is a very practical PCB assembly auxiliary system.

Key words: tag number query, coordinate transformation algorithm, positioning system
