Abstract: In order to reduce unsafe incidents and incidents of airport surface, a photoelectric surveillance warning method and system design scheme based on infrared and visible light sensors were proposed. Firstly, a panoramic photoelectric situation was formed through four steps, fusing, splicing, correcting and reconstructing infrared and visible images. Then, classification recognition and continuous tracking were conducted on moving objects of airport surface and classified warning was given for potential conflicts which were predicted through analyzing moving objects' behaviors and intentions. Finally, this solution was applied to one airport in southwest of China. The results show that integrated solution of photoelectric surveillance warning system can realize panoramic monitoring of large-scale airport scenes and achieve target recognition and tracking in complex weathers as well as intelligent conflict prediction and early warning. It is characterized by advantages of all-time, all-weather visual display, early warning and low cost, etc.
