摘　　要：为降低机场场面冲突事件的发生,设计一种机场场面飞机冲突告警系统。机场场面冲突检测过程分为两层:粗略检测层和精细检测层。粗略检测使用类包围球简化模型,精细检测划分飞机模型为5个凸多边形。为了提高算法检测速度,提出一种基于最近点的分离轴碰撞检测算法。此外,为降低虚警率,对顶点进行弧形检测。实验结果表明,该算法可有效降低程序时间复杂度,加快检测速度。此设计方案为实现低成本机场场面的冲突事件监控提供了重要参考。In order to reduce the occurrence of conflicts at the airport scene,an aircraft conflict warning system at the airport scene is designed.The collision detection process was divided into two layers:the rough detection layer and the fine detection layer.The rough detection used a bounding sphere simplified model,and the fine detection divided the aircraft model into 5 convex polygons.In order to improve the detection speed of the algorithm,a separation axis collision detection algorithm based on the nearest point was proposed.Furthermore,in order to reduce the false alarm rate,arc detection was performed on the vertices of the polygon.Experimental results show that this algorithm can effectively reduce the time complexity of the program and improve the detection speed.The proposed method provides an important reference for the scene monitoring at the scene of low-cost airports.
