Hawk-eye panoramic view design in visual simulation system based on axis V and angle α of rotation

针对航空模拟器视景仿真系统中利用欧拉角来处理鹰眼全景观察器视角旋转不可避免的出现万向轴锁现象,提出了利用四元素法来描述旋转,即绕任意一个轴V旋转一个角度α的方法来解决这一问题,并和欧拉旋转方法进行了简单对比.采用OSG+MFC(OpenSceneGraph+Microsoft Foundation Classes)来实现航空模拟器视景仿真系统中鹰眼全景观察器的方法,给出了应用实例,指出利用该方法构建的航空模拟器视景仿真系统中鹰眼全景观察器,可以为用户提供一个更加真实的沉浸感觉.

In aviation simulator of visual simulating system,universal shaft lock phenomenon is unavoidable by using euler angle to observe an eagle′s eye view angle rotation.In order to solve the problem,four element method,which is a rotating shaft V around angle α,is proposed to describe the rotating in this study.Using OSG＋MFC to realize the aviation simulator visual simulation system of an eagle′s eye view observation,the application example is given.In the aviation building of visual simulating system simulator,panorama eagle eye observation can provide a more adjacent immersed sense.
