Abstract
3D pose estimation plays an important role in human-computer cooperation and intelligent control. At present, the manipulator with sensor can realize spatial three-dimensional pose estimation, but the cost is too high. In this paper, the three-dimensional spatial positioning of the manipulator is carried out through the visual label. The two-dimensional pixel coordinates of the visual label on the manipulator are obtained by pasting the visual label on the manipulator and placing three cameras in different directions. By solving the three-dimensional coordinates of the manipulator through the three-dimensional vision fusion proposed in this paper, combined with the least square method to optimize the measurement results, multiple constraint equations can be established through multi-objective vision to improve the measurement accuracy, expand the motion range of the measured object, and have high robustness and economy. In the binocular vision pose detection, 89% of the measurement error within 2 m is less than 10 mm. The detection speed of the robot pose measurement system based on multi vision reaches 16 fps, and more than 96% of the measurement error within 2 m does not exceed 3 mm. Considering the needs of real-time monitoring of industrial detection in the production environment, it needs to have high robustness, and the multi vision pose detection scheme is recommended.
