The ASR (aerodrome surveillance radar) can not be applied for a medium and small airport due to its high cost, and multi cameras might be used instead of the ASR to monitor the aircraft's movements there. By using the image edge detection and morphological image process approaches, the moving targets are recognized. And the tracks of aircraft are extracted, as well as their motion parameters. The moving target tracking algorithms and the conflict detecting model based on the DCPA (distance of closest point of approach) and the TCPA (time of closest point of approach) are proposed, and a prototype system is developed and applied in one General Aviation Airport for the conflict detecting, which shows that the aircraft conflict is effectively detected by this model and the video image process approach, and the safety and the efficiency of the airport ground operation are enhanced.
