为了实现彩色栅格地图道路的全自动提取，提出了一种闭环反馈提取彩色

栅格地图道路的方法。在地图图像数学模型的基础上，根据地图中对象的颜色特征对地图图

像进行规范化处理。在采用一些算法去除噪声后提取道路，对道路进行细化处理。依据道路

和噪声的特征建立一些判据判断道路的正确性，把道路的提取变成了根据判据不断修正道路

的循环过程，实现道路的全自动提取。试验结果表明了该方法具有较高的准确性、全自动化

和通用性。-color raster to the road map automatic extraction, presents a closed-loop feedback extract color raster map the roads. Map images in the mathematical model, based on the target map of map features color image processing standard. Some of the algorithm used to remove noise from the road after the road is thinned. Based on road and noise characteristics to establish some criteria to judge the correctness of the road. Extraction of the road has become a criterion under constant amendments to the cycle path, the path of achieving automatic extraction. Test results show that the method has a high accuracy, fully automated and versatile.
