【摘要】：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。
[Abstract]:Because of the different ranging principles, the phase 3D laser scanner has the characteristics of high accuracy and short range compared with the pulse laser scanner. Taking the Z F IMAGER 5010C phase 3D laser scanner as the experimental object, the accuracy of the internal and external coincidence is calculated and analyzed from the distance, and the applicable conditions of the scanner for deformation monitoring are studied. The results show that the measuring accuracy of the Z F IMAGER 5010C scanner decreases with the increase of distance, the accuracy of internal coincidence is better than that of external coincidence, and the analysis results of the accuracy of internal coincidence show that, In the operation mode of setting target for scanning data registration, the monitoring of elevation and horizontal direction is carried out simultaneously. The scanner is controlled within 30 m from the scanning object and can be monitored for three stages of deformation. The result of precision analysis of external coincidence shows that, With the aid of total station measuring the coordinate of the center point of the target, the height and horizontal direction are monitored simultaneously in the operation mode of scanning data registration. The distance between the scanner and the scanned object is controlled within 20 m, and the third level deformation monitoring can also be carried out.
