Optimization of calibration method for scanning planar laser coordinate measurement system
摘要
Abstract
On the basis of angle measurement by a rotating planar laser in the single station and intersection in the multi-station, a coordinate measuring system was introduced,and its calibration method was optimized. With analyzing its features of special angle measurement and multi-sensor intersection measurement, the principle of azimuth information measurement by the single station and the system structure were described,then the calibration methods for structure parameters of single station and system parameters were studied. According to the characteristics of a rotating shaft and a laser plane,structure parameters were calibrated by theodolites through designed corresponding accessories, and the system calibration was realized by determining the laser planes in the initial place by using a receiver. In order to perfect the calibration technology, the main error factors affecting the calibration accuracy were analyzed, the calibration methods of structure parameters and the process of system calibration were modified. An integrative calibration method for the system was proposed. Experiments show that the measuring accuracy of the system has reached 0. 1 mm, which proves the calibration method is feasible, and can improve the calibration accuracy.关键词
