Abstract

Laser three-dimensional (3D) projection technology is a new laser application technology. The technology can be a wide range of aerospace manufacturing, 3D assembly of parts and other scenarios. Through the high-speed deflection device, the laser beam can be continuously projected at different positions on the surface of the object. Due to the Visual staying phenomenon, the circular laser beam can present the expected outline and pattern on the surface of the object, so as to realize the projection function. In this paper, we designed a laser 3D projection system based on binocular vision. It analyzes the existing system designs and system calibration methods, expounds the structure design of the laser 3D projection system based on binocular vision, and explains the workflow of the system. The system calibration experiment and the laser 3D projection experiment are also conducted, and the experimental error is analyzed. The results show that the average projection error of the system is 0.37mm at the working distance of the 1.8-2.2m, which meets the usage requirements in most scenarios
