摘要
基于徕卡Scanstation C10扫描仪的坐标测量原理及其测量精度,分析了扫描角度与扫描距离对点位误差的影响情况;利用该仪器按照设计的实验方案进行数据采集,之后提取所获点云的强度数据,并以强度平均值为指标研究了扫描角度、扫描距离、反射体材质对强度值的影响情况。综合研究表明,徕卡Scanstation C10扫描仪的最佳扫描角度为[0°,20°]、最佳扫描距离为[15m,40m]、最佳扫描材质为反射率较高的标准反射体。
Influences on point position error caused by scanning angle and scanning distance were analyzed in this paper, based on the coordinate measurement principle and the measurement precision of Leica Scanstation C10 Terrestrial Laser Scanner. We used this instrument to process data collection according to the planned experimental scheme, and extracted the strength data of acquired point cloud. And then, taking the strength average value as index, we studied the influences on strength value caused by scanning distance, scanning angle and reflector material. The comprehensive research show that the best scanning angle ranges of Leica Scanstation C10 Terrestrial Laser Scanner are 0° to 20°, the best scanning distance ranges are 15 to 40 m, and the best scanning reflector materials are standard reflectors with higher reflectivity.
