摘　　要：针对深水多波束测深侧扫声呐多源探测数据的实时可视化表达处理效率较低的问题,提出实时测深数据快速条带式动态网格化方法和动态不规则金字塔构建方法、实时侧扫数据条带式增量更新方法和基于极坐标的实时水体数据重采样方法,实现了全球框架下动态海底探测地形的实时三维渲染和快速侧扫图像及水体图像绘制.同时采用基于状态保护与转移机制的声纳设备控制方法,通过异步通信方式实现了安全友好的交互式操作过程.实验结果表明:该系统满足深水多波束测深侧扫声纳设备的显控需求,能够保障声纳设备作业安全、增强现场作业能力及数据发掘能力.In order to improve the real-time visualization of multi-source detecting data from deep water multi-beam bathymetric side-scan sonar, this work proposed a dynamic strip-map gridding method, a dynamic irregular pyramid construction method, a real-time massive side-scan data strip-map updating method and a real-time massive water column data resample method based on polar coordinate. The dynamic detecting submarine topography 3D rendering under global frame was achieved in real time, and the backscattering image and the fan-shaped water column image were drawn. In addition, a sonar device control method based on the state protection and transition which was implemented with asynchronous communication techniques was proposed, to achieve the safe and friendly user operation. Experimental results shows that this system meets the display and control demands of deep water multi-beam bathymetric side-scan sonar, and improves the safety and efficiency of the filed operation.
