| 摘 要： | 该文提出了一套简单实用的扫描线划地图矢量化方法。主要包括图像降噪、线划地物边缘增强、提取线划目标等预处理，二值化、细化、链式编码等矢量化算法。对彩色扫描地形图进行了实例研究。结果表明，此方法大大提高了矢量化的精度与质量，减少了工作量，实现了半自动矢量化。

| Abstract: | The paper presents a simple but practical vectorization method for Scan Line geographical map,including vectorization algorithms such as image noise reduction,edge enhancement of the object for line draw features,pre-processing for extraction line designated targets,binarization,thinning,chain coding,etc.It also provides a case study on color scan of topographic map.Tthe results indicate that the vectorization accuracy and quality can be greatly improved,with workload reduced in the semi-automatic vectoriza... |
