摘　　要：以坦克仿真训练系统中与地形匹配性为研究对象,利用OSG碰撞检测法作为坦克运动与地形视景匹配仿真研究方法,引入四元数法来计算坦克旋转轴和旋转角度,使坦克运动与地形能够匹配贴合,提出相交矢量法计算检测点,并将这种算法进行扩展,用于多相交矢量,可以满足不同地形状况下坦克运动与地面高低起伏匹配相关性的开发.Taking as the research object the matching degree between the terrain and the motion of tank in simulative training system, the problem how to define axes and angles of rotation is solved through building OSG models and introducing quaternion. Method of intersection vector is used to calculate the point of intersection, and quaternion method is introduced to get new rotation axes and revolving angles. Under these conditions, the motional model of tank and terrain can be shown in a proper way.
