摘　　要：随着人们对海底油气资源的开发,在海底铺设的管道越来越多,海底管道泄漏风险日益增加,亟需高效、实时的检测方法。文章利用自主式水下航行器(Autonomous Underwater Vehicle, AUV)平台,搭载多波束测深声呐与基于VxWorks的嵌入式处理单元,设计了一套水下气体泄漏自动检测系统,将多波束测深声呐采集的水体图像数据传送给嵌入式处理单元,采用模板匹配方法对图像数据进行处理,完成对海底管道气体泄漏点的实时检测。湖试和海试都验证了该系统方案的有效性与先进性。With the development of undersea oil and gas resources, more and more subsea pipelines have been laid on the seabed. There are also a large number of offshore pipelines will be constructed in the future. However, the risk of subsea pipeline leakage is increasing, and meanwhile, the efficient and real-time detection methods are urgently needed. In this paper, a set of underwater automatic gas leakage detection system is developed by using the Autonomous Underwater Vehicle(AUV) platform carrying the multi-beam bathymetric sonar and embedded processing unit with VxWorks. In this system, the water column image data collected by the multi-beam bathymetric sonar transmit to the embedded processing unit firstly, and then the template matching method is used to process the image data and complete the real-time detection of subsea pipeline. The efficiency and advance of the system have been verified by lake and sea trials.
