Design and Realization of Detecting Runway Incursion Model Based on Process of Video

Runway incursion is an important factor threatening the safety of civil aviation. The effective method of preventing runway incursion can improve the condition of safety on airfield. By using the algorithm of detecting moving objects on real-time video of airfield and bringing in an method of matching,the features of aircrafts contours to verify whether moving objects can accord with those features,which make detecting results suitable for airfield. A projection model which based on correlations between real-time video coordinates and the airfield plan coordinates has been set up. The model also can project the position of moving object into airfield plan. To verify those models availability. Simulation experiments have been made by using the technology of virtual control tower. The results show that: based on real-time video the proposed models can effectively detect moving object on airfield as well as the corresponding airfield plan,the condition of runway using and providing runway incursion alarming based on moving object's position,which provide supporting decision-making basis for airdrome controllers in an airport.
