多传感器信息融合的防波堤结构检测技术研究

Research on Detection Technology for Breakwater Structures Based on Multi-sensor Information Fusion

近年来,港口设施的快速发展,港口涉水工程的安全性和稳定性越来备受关注,针对港口防波堤受波浪、台风影响,导致水上结构损坏及水下结构产生结构断裂、破损、变形等现象,提出一种无人机LiDAR系统、SeaBat T50-P多波束测深仪、GPS RTK、Bv5000-1350三维扫描声呐测量系统等多传感器集成原理和数据融合方法,并进行可行性研究;试验表明,通过数据融合,有效的实现优势互补,获取的数据更加详细准确,为港口防波堤及其他港口水下设施检测提供可靠的技术支撑。

With the rapid development of port facilities,the safety and stability of port wading projects have attracted increasingly more attention in recent years.Under the influences of waves and typhoons on port breakwaters,the abovewater structures of breakwaters are damaged,and the underwater ones are subject to structural fractures,damage,and deformation.To address the problem,this paper proposes a method characterized by data fusion and a principle of multi-sensor integration of unmanned aerial vehicle(UAV)lidar system,SeaBat T50-P multibeam echosounder,GPS RTK,and BV5000-1350 three-dimensional scanning sonar measurement system.A feasibility study of the method is then carried out.The test shows that through data fusion,this method achieves complementary advantages and obtains more detailed and accurate data.The proposed method provides reliable technical support for the detection of port breakwaters and other underwater facilities at ports.
