摘 要: 提出了一种航空影像中的立交桥检测的算法。在给出了一类带有圆形或近似圆形转弯匝道的立交桥的描述方法的基础上,先进行主要干道检测,再采用改进的Hough变换对匝道进行检测,从而实现对立交桥的自动检测。实验结果表明,该方法是有效的。 An approach to automatic detection of interchanges in urban aerial images is presented. A description for interchanges with circular or nearly circular turning branches is introduced, on the basis of which main roads are first detected, and then a modified Hough transform is applied to find out turning branches, thus to give the evidence of the existence of interchanges. Experiment results show the effectiveness and efficiency of the proposed method.
