摘要
为研究长距离地面三维激光扫描仪在矿山勘测中的数据质量,以三维激光扫描系统的点云坐标测量和坐标转换为基础,设计了RIEGL-VZ2000i三维激光扫描仪在矿山勘测中的精度检测试验,从扫描结果的内符合性和外符合性评定RIEGL-VZ2000i的单站扫描精度。结果表明,RIEGL-VZ2000i在良好的观测环境和测距500 m内,单站扫描距离、平面、高程的内符合误差分别为0.005,0.010,0.020 m左右,随距离变长其误差呈同步增大趋势;单站扫描距离、平面、高程的外符合误差分别为0.010,0.010,0.050 m左右,具有较高的精度,能够满足矿山土石方量等测量需求。研究结果对长距离地面三维激光扫描仪的精度评定研究和项目生产应用提供了一定的参考。
In order to study the data quality of long-distance ground 3D laser scanner in mine survey,based on the point cloud coordinate measurement and coordinate conversion of 3D laser scanning system,It is designed the precision detection test of RIEGL-VZ2000i 3D laser scanner in mine survey.The single station scanning accuracy of RIEGL-VZ2000i was evaluated from the internal and external conformance of scanning results.The results show that in a good observation environment and 500 m range,the internal coincidence errors of the scanning distance,plane and elevation of the single station are about 0.005 m,0.010 m and 0.020 m respectively,and the errors increase synchronously with the increase of the distance.The external conformity errors of single station scanning distance,plane and elevation are about 0.010 m,0.010 m and 0.050 m respectively,which has a high accuracy and can meet the measurement requirements of mine earth and gravel volume.The research results of this paper provide a certain reference value for the accuracy evaluation of the long distance ground 3D laser scanner and the project production and application.
