Abstract
This invention discloses a high-precision positioning method based on vision-based bit encoding, comprising: fabricating a bit code standard ruler according to design specifications and installing it parallel to the movement direction of the moving mechanism; installing a high-speed recognition camera on the moving mechanism to acquire bit code images of corresponding positions in real time; preprocessing the images and identifying the position information of the moving mechanism, thereby achieving high-precision assisted positioning. This invention, through visual recognition of bit codes, can obtain the position of the moving mechanism in real time and accurately, possessing the advantages of high positioning accuracy and good real-time performance, and can be widely applied in precision motion control and automation equipment.
