| 摘 要： | 工程边坡作为水利水电、矿山运输等工程中最为常见的地质形态,是地质编录中主要的处理对象。现今的地质编录对于平面边坡已经能够很好地解决并生成正射影像,但对曲面边坡的建模与展示研究还比较少。本文给出一种基于斜轴圆柱曲面边坡建模的方法,并将影像投射到展示平面上生成正射影像。实践表明,建模方法实用、快捷,模型展开方法较简单,精度符合地质编录要求。

| Abstract: | Engineering slope is the most common form in water and hydroelectric projects,mining and transportation engineering,and it is main processing objects in geological catalog.Nowadays,flat slop in geological logging has been able to be solved well,but surface slope not be good.Research on modeling and expansion for surface slope is also less.This paper proposed a modeling method based on oblique cylindrical model,and took the original image projection onto plane after modeling.Experiment showed that modeling method was practical,speedily,and expansion was simple,the accuracy was in line with geological documentation requirements. |

| Keywords: | surface slope oblique cylindrical model expansion |
