The invention provides a three-dimensional laser positioning projection device. Thethree-dimensional laser positioning projection device comprises a laser ranging module, a binocular stereoscopic vision module, a laser projection module and a control module; the laser ranging module is used for scanning and measuring the characteristics of a workpiece, establishing a coordinate conversion relation between the workpiece without a cooperative target and a projection system, and realizing workpiece positioning; the binocular stereoscopic vision module is used for identifying a cooperative target and measuring the position of the target, establishing a coordinate conversion relation between theworkpiece without the cooperative target and the projection system, and realizing workpiece positioning; the laser projection module is used for projecting a three-dimensional laser pattern after positioning; and the control module can control the laser projection module to project the laser pattern to a target based on information of the laser ranging module or the binocular stereoscopic vision module. Two positioning methods of vision and laser ranging are adopted, positioning of workpieces with cooperative targets can be achieved, positioning of workpieces without cooperative targets can also be achieved, practicability is high, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of laser projection, in particular to a three-dimensional laser positioning projection device. Background technique [0002] The positioning projector is mainly used for composite material layup, high-precision component installation and positioning, pattern spraying, etc., and assists other processing equipment to complete layup, positioning and spraying through the projected laser pattern model. The positioning projector It can improve work efficiency and accuracy, reduce human marking errors and missing items, realize the digitalization of the manufacturing process of important equipment such as aircraft, and ensure the performance of the system. [0003] The positioning projector in the prior art scans the workpiece by laser to determine the distance of the workpiece to achieve positioning. However, when the laser scanning method is aimed at different object structures, there are certain differences in p...
