摘　　要：在复杂海况下,对水下的水工建筑物进行三维检测精确定位分析,目前有多种设备可选择。但检测的可靠性和精度需要进一步分析和验证。为此,结合广东揭阳石化原油码头工程,采用多波束测深仪系统和水下三维实时3D声呐系统,以点云数据建模,将2种系统采集的数据融合处理,可对建筑物的坐标和高程进行精确分析。其中,多波束测深仪系统可用于水下建筑物绝对坐标的测量,而实时3D声呐系统可取得目标物精确的模型图像,2种数据融合处理后,即可用可视化的方法对目标物的位置和状态进行准确分析。该方法可用于港口和码头维护以及水下建筑物检测,为老码头的改造、修复提出有效的检测定位方法和可视工具。Under complex sea conditions,there are many kinds of equipment available for 3D detection and accurate positioning analysis of underwater hydraulic structures.However,the reliability and accuracy of the detection need to be further analyzed and verified.Combining with Guangdong Jieyang Petrochemical Crude Oil Terminal Project,we adopt the multi-beam echo-sounder system and the underwater 3D real-time sonar system,and build model with the point cloud data.The data collected by the two systems are integrated and processed,and the coordinate and elevation of the building are accurately analyzed.The multi-beam echo-sounder system can be used for measuring the absolute coordinates of underwater structures,and the real-time 3D sonar system can obtain accurate model image of the target object.Integrating and processing the two kinds of data,we can accurately analyze the position and state of the object by the visual method.This method can be used for the harbor and wharf maintenance,underwater building inspection,and provide an effective detection and positioning method and visual tools for the reconstruction and restoration of old wharves.
