提出了一种自动估计道路中心线矢量地图与高分辨率卫星影像之间转换参数的方法。该方法的优点是避免了全局图像特征提取，以矢量数据为指导，同时实现了特征提取和匹配。道路宽度，估计的算法，连同道路方向被用作约束条件，以改善匹配结果。适当选择道路节点有助于改善调整。地图到影像匹配具有影像到影像匹配所不具备的优点，是一种快速更新地理信息系统（GIS）数据的好方法。
A method for automatically estimating the transformation parameters between road centre‐line vector maps and high resolution satellite images is proposed. The advantages of the method are that global image feature extraction is avoided and feature extraction and matching are achieved simultaneously by using the vector data as guidance. The road width, as estimated by the algorithm, together with the road direction are used as constraints to refine the matching results. Arbitrarily chosen road nodes contribute to improving the adjustment. Map‐to‐image matching has advantages over image‐to‐image matching and could be a good method for the rapid updating of geographical information system (GIS) data.
