摘要
针对某型头盔瞄准具仿真的工程需求,使用头位跟踪传感器以四元数法测量头盔相对于飞机机体坐标系的角度,变换为欧拉角后通过共享内存传给计算机控制模块;使用光栅、半透半反棱镜等光学组件结合数字控制电路实现头盔瞄准具眼镜显示系统功能;利用计算机控制系统进行逻辑控制和仿真管理,成功实现了对头盔瞄准具的仿真。仿真系统性能达到实装以上水平,完全满足模拟训练需求。
Aiming to the engineering requirement of simulating a helmet mounted sight, the angles between the helmet mounted sight and the plane coordinate system are measured by head position tracking sensor in quaternion method. Then they are transformed to Euler angles and sent to computer control modules by shared memory. Integrated with digital control circuit, the display system functions of helmet mounted sight glasses are realized by using the raster and the half transparent and half catoptric prism. The computer control system are used to implement logic control and simulation management, then the simulation to the helmet mounted sight is successfully implemented. The simulation system can meet the demands of simulation training.
