Abstract:

Aiming at the characteristics of area grey and edge line of runway, an algorithm for recognizing runway based on straight line characteristics is presented to achieve runway recognition correctly. Firstly, the edge detectors are used to get a edge image which has been number normalized, and straight lines are extracted in the edge image. Then the straight lines are connected three times and the parallel straight lines couple is extracted. Finally, the runway of airport is validated according to the characteristics of area grey. Many experiments show that this method can find the runway of airport exactly and quickly in aerial images, and is robust for the influence of cloud cover and noise. Experimental results verify the effectiveness of the proposed algorithm.
