Abstract: To address the limitations of traditional three-dimensional reconstruction methods,which have a limited field of view and are difficult to apply to the three-dimensional reconstruction of moving targets,a three-dimensional reconstruction method for moving targets based on a dual-galvanometer system is proposed.The dual-galvanometer system is utilized to construct a stereo vision-like architecture,combined with a high-speed camera to achieve stable acquisition of moving target image sequence.This effectively expands the reconstruction scene range while reducing the motion blur during target movement,ensuring image acquisition quality.By preprocessing the acquired images and extracting point cloud information frame by frame,the point cloud stitching algorithm is used to achieve three-dimensional reconstruction of the moving target.Experimental results show that compared with traditional vision systems,the dual-galvanometer system can expand the measurement field of view by 2.10 times,significantly increase the number of point clouds,and significantly reduce the reconstruction error of each part of the target.
