备注

由于测距原理不同,相位式地面三维激光扫描仪相较于脉冲式具有测量精度高、测程短的特点。文中以Z+F IMAGER 5010C相位式地面三维激光扫描仪为试验对象,从距离入手,对其内、外符合精度进行了计算分析,并研究了此扫描仪用于变形监测的适用条件。结果 表明:Z+F IMAGER 5010C扫描仪的测量精度随着距离的增加而降低; 内符合精度要优于外符合精度; 内符合精度分析结果表明,在设置靶标用于扫描数据配准的作业方式下同时开展高程、水平方向的监测,扫描仪距离扫描对象控制在30 m之内,可进行三级变形监测; 外符合精度分析结果表明,借助全站仪测量靶标中心点坐标用于扫描数据配准的作业方式下同时开展高程、水平方向的监测,扫描仪距离扫描对象的距离控制在20 m之内,亦可进行三级变形监测。

Because of the different distance measurement principles,the phase terrestrial 3D laser scanner has the characteristics of high measuring accuracy and short measuring range.This paper taking Z+F IMAGER 5010C phase terrestrial 3D laser scanner as a test object,calculates its internal and external accuracy through distance measurement,then the applicable conditions of the scanner for deformation monitoring is studied.The results show that the measurement accuracy of Z+F IMAGER 5010C scanner decreases with increasing distance,internal accuracy is better than external accuracy; internal accuracy result shows that the scanner can carry out three level deformation monitoring by the setting of fixed targets of paper for scan data registration,the distance between scanner and the objects should be controlled within 30 m; external accuracy result shows that the scanner also can carry out three level deformation monitoring by using total station to get the center coordinates of paper target for scan data registration,but the distance between scanner and the objects should be controlled within 20 m.
