Abstract: We first extract the points of the kilometer grid by Hough transform, then calibrate their positions against the theoretic coordinates calculated by the map label and rectify the errors in scanning map. We have created the automatic tools for scanning map using this method.
摘要： 利用Hough变换检测地形图中的方里网网点坐标，并由地形图图幅编号计算得到方里网网点的理论坐标，再把方里网网点的理论坐标与相应Hough变换搜索得到的方里网网点图像坐标进行最小二乘拟合，以纠正扫描地形图的误差得到精确的方里网网点坐标。结合该技术形成了自动扫描生成数字栅格地图的软件系统。
