港口工程大范围场景建模技术研究

On modeling technique of large-scale scene in harbor engineering

虚拟现实技术在港口工程中已有较为广泛的应用,但大范围场景建模效率仍较低。基于遥感影像,对地形模型进行纹理映射,并对遥感影像上地物的特征进行分析与提取,利用程序化建模技术,可快速、精细地构建出港口工程大范围场景模型。

Virtual reality technique has been widely used in harbor engineering.But poor efficiency is the main problem for building the model of large-scale scene.Based on the remote sensing imagery,the texture mapping for the terrain model is realized,and the characteristics for objects on the remote sensing imagery are analyzed and abstracted.Adopting programming modeling technique,the efficiency and quality for building the model of large-scale scene in harbor engineering are improved greatly.
