Research on laser 3D projection technology based on non-cooperative targets

Laser 3D projection technology is a new type of laser application, mainly used for composite material bedding, high-precision parts installation and positioning, pattern spraying and other aspects. As an auxiliary system in intelligent manufacturing, laser 3D projection technology is widely used in aerospace manufacturing, 3D parts assembly and other scenarios. The test software is developed based on the embedded system. According to the imported CAD model and positioning system to obtain position information, so as to plan the area of laser pattern projection. The laser 3D projection system uses a high-speed deflector to project a laser to achieve positioning work or laser projection work, and assist other processing equipment to complete the layup, positioning and spraying work. In this paper, we design a laser 3D projection system based on non-cooperative targets. It analyzes the existing system design and system calibration methods, and expounds the structural design and workflow of the laser 3D projection system. While improving work efficiency and accuracy, it can also reduce the artificial scoring errors and missing items in the traditional methods, realize the digitalization of the manufacturing and production process of important equipment such as aircraft, and ensure the performance of the system.
