摘要 为了解决大尺寸空间测量场建立过程中会出现测量效率无法保证、精度不达标,以及测量过程中任务经常有遗漏等问题,对测量场的建立进行了规划研究。以激光雷达测量系统为载体,采用蒙特卡洛仿真方法对系统的测量模型进行分析,并对测量场全周期的建立过程,即系统站位配置、转站点布置优化、数据采集方式选择以及测量数据的预处理等进行了理论分析和实验验证。结果表明,经过规划的激光雷达测量场精度可以达到0.05mm以内,单点测量精度达到0.1mm以内,符合大尺寸空间测量场精度要求,实现了对测量场的规划评估。此研究对于大尺寸测量领域具有一定的意义。 In order to solve the problems that the measurement efficiency cannot be guaranteed,the precision is not up to the standard,and the task is often omitted during the measurement process,the establishment of the measurement field was planned and studied.Taking lidar measurement system as the carrier,the measurement model of the system was analyzed by monte carlo simulation method,and the establishment process of the whole period of the measurement field,including station configuration,station layout optimization,data acquisition method selection and measurement data preprocessing,was theoretically analyzed and experimentally verified.The results show that the precision of the planned lidar measurement field can reach less than 0.05mm,and the single point measurement precision can reach less than 0.1mm,which conforms to the accuracy requirements of the large-size space measurement field and realizes the planning evaluation of the measurement field.This research has certain significance in the field of large-scale measurement.
