摘要: 徕卡MS60不仅能获得高精度的单点坐标,还可以得到激光点云和图像数据,各传感器的同轴性为获得同一坐标框架下的变形监测数据提供了便利。本文根据不同类型数据探测形变的优势,利用徕卡MS60的望远镜相机采集监测区域的图像拼接形成全景图像,再结合扫描得到的点云数据构建深度图像,通过多期深度图像匹配得到监测区域的三维位移矢量。试验表明,基于深度图像的监测方法为变形监测提供了新的思路。

Abstract: Leica MS60 can obtain not only high-precision single point coordinates, but also point cloud and image data. All these data, with their respective advantages, are in a common coordinate system, and this brings convenience for deformation monitoring. The telescope camera is used to gather the images of the monitoring area to form a panoramic image, and then combine the point cloud to construct a depth image. The three-dimensional displacement vectors of the area are obtained by multi-period depth image matching. The monitoring method based on depth image provides a new idea for deformation monitoring.

Key words: deformation monitoring, scanning total station, coordinate transformation, depth image
