To avoid the disadvantages of current algorithms,an effective line extraction algorithm is presented.Firstly,the aerial image is processed by means of small-scale Gaussian filtering.Then,by means of edge detection,an edge detection amplitude image is obtained;and heuristic search is applied in the edge detection amplitude image,so as to extract line search trajectories fitted the line model.Finally,the line from the search trajectories is selected.The experimental results show that our algorithm can extract the true line in the aerial image,and is an effective line extraction algorithm.
