The invention relates to the technical field of bridge monitoring, in particular to a de-observation station three-dimensional laser scanning bridge monitoring system and a monitoring method.The de-observation station three-dimensional laser scanning bridge monitoring system comprises an unmanned aerial vehicle and a three-dimensional laser scanning device erected on the unmanned aerial vehicle, an anemograph is arranged on the unmanned aerial vehicle, and an acquisition module and a correction module are arranged in the unmanned aerial vehicle; a three-dimensional modeling system is also arranged in the unmanned aerial vehicle; a point cloud preprocessing module, a point cloud denoising module and a laser point cloud module are arranged in the three-dimensional laser scanning device, and a point cloud registration system matched with the three-dimensional modeling system is further arranged in the three-dimensional laser scanning device. The three-dimensional laser scanning device is installed on the unmanned aerial vehicle, the unmanned aerial vehicle and the three-dimensional laser scanning device are combined, a non-contact measurement mode is adopted, and a supporting point does not need to be arranged on the ground, so that a bridge far away from a land section can be monitored, meanwhile, the labor intensity of data acquisition work is greatly reduced, and automatic data acquisition is realized.

    本发明涉及桥梁监测技术领域,尤其涉及一种去测站化三维激光扫描桥梁监测系统及监测方法,包括无人机与架设在无人机上的三维激光扫描装置,无人机上设置有风速仪,且无人机的内部设置有采集模块与纠偏模块,并且无人机的内部还设置有三维建模系统;三维激光扫描装置内部设置有点云预处理模块、点云去噪模块与激光点云模块,且其内部还设置有上述三维建模系统相适配的点云配准系统。通过在无人机上安装三维激光扫描装置,使无人机与三维激光扫描装置结合,采用非接触式测量的方式,无需在地面上设置支撑点,从而可对远离陆地段的桥梁进行监测,同时极大地降低数据采集工作的劳动强度,实现了数据的自动化采集。
