Research on the measurement field planning of lidar measurement system

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.
