摘要
本文介绍了直接基于彩色地图的交互式矢量化方法。这种方法通过样本学习、色彩距离度量、模糊选点等技术，较好地解决了如等高线一类的细线型要素的矢量化要求，达到了半自动的程度，具有较大的实际意义。
In this paper, the method of interactive vectorization directly based on color map is introduced. This method resolved the vectorization problem of thin line such as contours through the techniques of samples studying, color distance measurement and selecting point puzzyly. It makes the system become semi-automatic and is practical.
