摘要
对彩色地图中道路信息的识别与提取方法进行了研究,根据道路自身的特征,提出了一种利用圆形度与颜色特征相结合的提取方法,同时,对若干相关问题进行了详细的介绍,如区域标记、圆形度等。还介绍了对道路信息提取之后的细化和矢量化,并着重描述了道路细化过程中形态变换的用法。通过研究可以得出,利用这种提取方法可以使处理的结果更准确,而且在提取的过程中可以很自然的把道路上的文字等噪声去掉。
The method of recognizing and extracting the roads in colorful map is studied. According to the characteristic of the road, there is a method to be proposed: Make use of the circular degree and the color characteristics combine together, and there are some related problem to be introduced, for example: district marking, circular degree and so on. Besides, thinning and vectorization are both introduced. Particularly, mathematical morphology transformation algorithm sinskeletonizing processing of imagesare des cribed.Through the study, there is result that making use of this extracted method is able to get good processed result and erase the characters noise of the road in the process of extracting.
