| Abstract: | The extraction results of the building s vertical edges based on the high resolution aerial image can do much help in the process of obtaining the building s height and the building s recognition.After analyzing the features of the vertical lines on the RS image,a method that is used to extract these lines is proposed,and it uses the Hough transform with constraint conditions on the basis of image edge detection and the image thinning.Experiment results show that this method is available and effective. |
