苏南运河镇江段航道3维可视化技术及其应用研究

航道3维可视化对全面掌握运河河底地形地貌,保障运河水上交通安全具有重要意义。本文以3维可视化苏南运河镇江段航道为例,阐述如何在实现航道周边场景3维渲染的基础上,利用航道数字测深数据,创建基于格网的数字水深模型,进而生成河底数字高程模型的过程,并对航道3维可视化技术的实际应用进行了探讨。

Channel 3D Visualization Technique of Zhenjiang Section of Sunan Canal and Its Application Study

Channel 3D visualization is important in the complete understanding of topographic features of channel bottom and ensuring the safety of water traffic. Taking the 3D visualization of the Zhenjiang channel section of Sunan canal as an example, based on the re- alization of 3D visualization of channel surrounding scene, this paper elaborates on the way of building digital soundings model based on grid using channel digital sounding data, and then builds channel bottom digital elevation model and discusses the application of channel 3D visualization technique.
