摘　　要：人在搜索目标的过程中,头动和眼动的耦合随动关系类似于光电稳瞄稳像技术中的二级稳定,头部运动完成概略观察方向稳定对准,眼球运动完成对目标的精细稳定对准。提出的基于眼球定位和头盔定位的综合视线跟踪技术,利用头盔定位得到头盔瞄准线相对飞机轴线的方位和俯仰角,以及眼球定位得到视线相对瞄准线的方位和俯仰角,将两者叠加,得到视线相对飞机轴线的方位和俯仰角。由于人眼运动的复杂性,通过采用稳定防抖动技术和对眼动规律的研究,实现眼球的实时、稳定跟踪。综合视线跟踪技术提升了头盔显示器定位能力,瞄准速度快捷灵敏,使驾驶员在瞄准和借助视频设备观察时,能完全符合人的生理习惯和需求。In the process of searching for a target,the coupling serro relationship between head movement and eye movement is similar to the secondary stability in the photoelectrostabilized sighting image stabilization technology,the stable alignment of the general observation direction is completed by the head movement,and the precise and stable alignment of the target is completed by the eye movement.The proposed comprehensive line of sight tracking technology based on eyeball and helmet positioning get azimuth and pitching angle of axle of plane relative to helmet’s aiming line with helmet positioning and azimuth and pitching angle of aiming line relative to aiming line watch eyeball positioning,combination of the two systems can get azimuth and pitching angle of axis of plane relative to view line.Due to the complexity of human eye movement,through the use of stable anti-jitter technology and the study of eye movement rules,real-time and stable tracking of the eyes is realized.The comprehensive line of sight tracking technology improves the positioning capability of helmet display,aiming speed is fast and agile enabling the driver to fully meet the physiological habits and needs of people when aiming and observing with the help of video equipment.
