针对维修仿真中物体之间存在的穿越问题,提出一种混合碰撞检测处理算法。该算法结合轴向包围盒的快速性及几何约束的精确性,采用轴向包围盒改善虚拟人与虚拟物体之间的碰撞效果,运用几何约束算法解决虚拟人所携带零件与其他零件之间的穿越问题。实验结果表明,该算法的实时碰撞检测效果较优。

An collision detection algorithm based on Axis Aligned Bounding Box（AABB） and geometrical restriction is proposed to solve the problems of collision between different objects in maintenance simulation.It adopts AABB to improve the effect of collision detection between the virtual human and others objects.Geometrical restriction algorithm is used to solve the problem of collision detection between the accessories belong to virtual human and the others.Collision detection algorithm combines the speediness of AABB and exactitude of geometrical restriction,and experimental results indicate that it makes real-time collision detection effective.
