| 摘 要： | 本文提出了一种从航空照片中提取主要道路交叉口的方法.本方法是基于道路交叉的几何-统计模型来实现自动检测的.首先检测可能存在道路交叉口的候选区域,然后再针对候选区做道路交叉口参数的提取,最后根据道路交叉口的模型进行证实.实验证明该方法具有检测准确性高、速度快、抗噪能力及鲁棒性强的优点.

INTERSECTIONS AUTOMATIC DETECTION IN AERIAL PHOTOS |

| Abstract: | A method is proposed to extract intersections of high streets in aerial photos. Based on the geometrical and statistical model of intersections, the process is conducted in three steps. Candidate regions that may contain intersections are first detected, then calculate intersection parameters for the candidate regions, last make confirmation according to the model. Experimental results showed that the method is fast and robust, and has high precision even in noisy condition. |
