摘　　要：防波堤作为关键基础设施,由于其特殊地理位置、独特的地质条件和复杂的构筑材料等因素,运行环境异常复杂,承受着巨大风险,因此防波堤很容易出现变形和破损等现象。为了检测防波堤堤身及周边抛石的现状,提出了一种多传感器信息融合水陆一体化测量方法,该方法包括无人机航摄系统、多波束测深系统、便携式侧扫声呐和浅地层剖面仪系统等设备,通过将采集的3D点云、边界线、海底泥层厚度等多种数据结合ICP算法进行数据融合处理,可以获取更加精确的测量数据,并且不同传感器之间实现了优势互补。这种水陆一体化测量方法能够更加有效、直观地了解水上结构的变化和水下工程的冲刷情况,为更好地评估和监测防波堤的状态提供有效的技术支撑。As a key infrastructure,port breakwaters are prone to deformation and damage due to their special geographical location,unique geological conditions,and complex construction materials,resulting in extremely complex operating environments and enormous risks.In order to detect the current situation of port breakwaters and surrounding riprap,a multisensor information fusion water-land integrated measurement method is proposed.This method includes equipment such as unmanned aerial vehicle aerial photography system,multi beam bathymetry system,portable side scan sonar,and shallow layer profiler system.The collected 3D point cloud,boundary line,seabed mud layer thickness,and other data are combined with ICP algorithm for data fusion processing,more accurate measurement data can be obtained,and the advantages of different sensors are complementary.This water-land integrated measurement method can more effectively and intuitively understand the changes in water structures and the erosion situation of underwater engineering,and provide effective technical support for better evaluation and monitoring of the status of breakwaters.
