本文以等高线的分层识别和地形立体显示系统为研究目标,建立了一个以军用彩色纸地图作为原始输入资料来实现该系统的基础环境。采用自动与半自动相结合的处理方案,针对其中的几个疑难问题,如彩色纸地图的彩色分层处理,等高线的断线修补及等高线高程值的推算提出了一些简单有效的解决方法,为今后进一步的研究和开发打下了良好的基础。 In this paper, the stratigraphic identification of contour lines and terrain stereoscopic display system as the research goal, a military color paper map as a raw input data to establish a basic environment for the system. The automatic and semi-automatic processing schemes are adopted to solve some of the difficult problems such as color layering of color paper map, repair of broken contour lines and calculation of elevation values ​​of contour lines. Some simple and effective solutions are put forward Method, which laid a good foundation for further research and development in the future.
