Automatic loopback three-dimensional reconstruction system and operation method

The invention discloses an automatic loopback three-dimensional reconstruction system and an operation method, the system comprises a mobile scanning equipment module and loopback base unit modules, and the number of the loopback base unit modules is determined according to the crossing condition of actual working condition paths. The mobile scanning equipment module comprises a laser radar module, a camera module, an attitude sensor module, a driving unit, a calculation unit, a key, a display screen and a loopback socket unit; according to the technical scheme provided by the invention, the problems of point cloud alignment and loopback point marking are solved in a mode of supporting system hardware to automatically trigger loopback, and the problem of accumulated errors of the point cloud in a three-dimensional reconstruction system based on the laser radar is effectively solved, so that a reliable three-dimensional point cloud modeling result can be obtained. 本发明公开了一种自动回环三维重建系统及运行方法，系统包括移动式扫描设备模块和回环底座单元模块
