Display and control system for deep water multi-beam bathymetric side-scan sonar

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.
