摘要：Bridges over water are one of the most important geo - spatial objects and military objects. Automatic recognition and extraction of bridges from remote sens ing images is very important and urgent for map updating and military application. I n this p aper a new algorithm for simultaneously recognizing bridges and registering image is presented. The basic assumption for new algorithm is that the bridges and the water have no big changes between remote sensing images and GIS data. The main idea of new al gorithm can be parted into four steps: the extraction and recognition of water areas, the extraction and recognition of bridges from remote sensing images, the extraction of un change d features between recognition results and GIS data, image registration us ing corresponding features. S ome effective image processing algorithms including the so - called OTSU image segmentation algorithm, the mathematical morphology algorithms are applied for features extraction of bridges and the water. Considering the different properties of image and GIS vector data, t he shape - based feature matching is employed for image registration with old GIS data. The primary experiments results show new algorithm is effective
