Abstract
Abstract
In this paper, based on the research of the basic principle of laser tracking measurement, a variable field of view laser radar tracking measurement system was designed. The system can be divided into three parts: laser scanning and ranging module, data processing module and double galvanometer field of view capture tracking module. According to the application requirements, the overall scheme of the optical system and mechanical structure was determined, and the three-dimensional model of the tracking measurement system was established. Based on the debugging of the system, tracking measurement experiment of targets field of view was completed. Through the experimental study of the variable field of view, the results show the feasibility of the variable field of view measurement target. Advantage analysis was performed by comparing the experiments of full field of view scanning. The variable point field system has a higher point cloud density than the full field of view. It can meet various tasks such as equipment manufacturing and installation, engineering measurement, and construction. demand.
