在研究飞行器模拟仿真中,为解决飞行器碰撞检测实时性的有关问题,首先对传统算法与模型进行了研究,并在此基础上改进了传统的空间分解方法,提出了改进的飞行模拟碰撞检测算法。该模型对飞行器所在空间进行分解,并对飞行器进行初步碰撞检测,在该基础上,对可能发生碰撞的飞行器建立包围盒,然后对包围盒进行快速判交来判定飞行器之间是否发生碰撞。仿真结果表明:该算法降低了时间复杂度,为仿真的实时性提供了可靠的保障。
In the research of aircraft simulation, in order to solve the real-time problem of aircraft collision detection, the traditional algorithms and models are studied firstly. On the basis of this, the traditional method of spatial decomposition is improved and an improved flight simulation collision detection algorithm . The model decomposes the space where the aircraft is located and detects the initial collision of the aircraft. Based on the model, a bounding box is established for the aircraft that may collide with the aircraft, and then the rapid determination of the bounding box is performed to determine whether there is a collision between the aircraft. The simulation results show that the algorithm reduces the time complexity and provides a reliable guarantee for the real-time simulation.
