Research on Building A Data Visualization System Based on a Seabed Model —Take the Hong Kong-Zhuhai-Macao Bridge as an Example

The data visualization system of the sea-crossing bridge is an intuitive observation and evolution analysis of the bridge and the seabed topography, landform, and strata at the top of the tunnel around the bridge, assisting maintenance personnel to carry out operations and providing support information for decision makers. Through the fusion of multi-source seabed topography data, providing two-dimensional, three-dimensional, and infographic visualization of these data is a key link in building a visualization system. This paper mainly introduces three types of submarine terrain detection technologies, namely multiple beams, side-scan sonar, and shallow stratigraphic profile, as well as the key algorithms in the process of data post-processing, and visualizes the surrounding terrain of the Hong Kong-Zhuhai-Macao Bridge through data fusion.
