就纸质地图等高线计算机自动提取展开讨论，结合计算机图形学、图像处理和模式识别等理论，提出了一套基于VC++开发平台的 具体实现算法。实验表明该方法获得了比较满意的提取效果，可以在GIS和军用仿真领域中进行推广。-on paper maps, contour lines from the computer automatically begun discussions with computer graphics, image processing and pattern recognition theory, a VC-based development platform to the specific algorithm. Experiments show that the method was quite satisfied with the extraction, the GIS and military simulation area for the promotion.
