Abstract The generation of 3D image is of great significance for underwater exploration. Direct generation underwater 3D images by forward looking sonar are more complicated and have a low resolution. This paper introduces an algorithm for reconstructing 3D altitude information of underwater objects from single 2D sonar image. Underwater information is acquired by a remote operated vehicle (ROV) equipped with an active forward looking sonar. Using the measurement mode provided by the viewpoint software, the altitude information of the object is extracted according to the acoustic shadow information and the echo distance in a single sonar image.

基于移动主动声纳检测的三维高度信息重建

摘要 3D图像的生成对于水下探测具有重要意义。前视声纳直接生成水下3D图像比较复杂，分辨率低。本文介绍了一种从单个 2D 声纳图像重建水下物体 3D 高度信息的算法。水下信息由配备有源前视声纳的遥控车辆 (ROV) 获取。利用视点软件提供的测量模式，根据单幅声纳图像中的声影信息和回波距离，提取物体的高度信息。
