Abstract: As the latest Leica RTC360 ultra-fast 3D laser scanner, it is simple to operate and fast to scan, and it can complete the acquisition of massive and rich point clouds and high-definition images in the shortest possible time, with comprehensive data, rich details, and extremely greatly improved work efficiency in the field. It is very intelligent. Using VIS vision tracking technology, through tracking and positioning of the scanner position, it can achieve real-time stitching of the point cloud during the acquisition process, without the need for targets, public points, and manual intervention, real-time viewing of the point cloud pre-stitching in the field. It can greatly reduce the workload in the industry. In the later stage, the Cyclone Register 360 intelligent splicing software is used. The point cloud does not need manual intervention. The point cloud implements automatic intelligent splicing processing, which enables simple and efficient field collection and internal data processing.
