摘要
为将平视显示技术与增强现实技术相结合,让驾驶员在平视状态下获取车速、转速、油量、实时导航等信息,还可以对车外的实时道路环境进行识别,并显示出相应的数据信息,从而避免驾驶员因低头查看驾车信息而产生的视野盲区时间,减少潜在的交通事故。文章采用自由曲面离轴反射光路结构设计车载平视显示系统,但由于其光学系统中的像差也更难以矫正,故通过改进光学元件减小像差方法达到设计目的。从光学角度对汽车AR-HUD虚像显示原理进行分析从而进行成像质量分析。为对光学元件进行合理优化,在研究相关设计参数研究之余,借助Zemax实现光路最终实现光学元件像差的减小。
To combine head-up display technology with augmented reality technology,the driver can obtain real-time navigation information such as speed,speed,oil quantity and so on in the head-up state,which can also identify the real-time road environment outside the vehicle,and display the corresponding data information,so as to avoid the driver because of looking down the driving information caused by the blind field of vision time,reduce the potential traffic accidents.Therefore,the free-form surface off-axis reflected light path structure is adopted in this paper.However,since the aberration in its optical system is more difficult to correct,the design goal is achieved by improving the method of reducing the aberration of optical elements.The principle of automotive AR-HUD virtual image display is analyzed from the optical point of view to analyze the image quality.In order to optimize the optical elements reasonably,ZEMAX is used to realize the optical path and finally achieve the reduction of optical element aberration in addition to the study of relevant design parameters.
