抬头显示系统成像参数测量技术现状分析

Analysis of present status of imaging parameter measurement technology in head-up display system

车载抬头显示系统可有效降低因驾驶员低头看仪表导致的交通事故率,将成为未来车载仪表显示发展的必然趋势。由于抬头显示器是通过投影的方式形成虚像,对其成像质量和距离等关键参数的测量相对困难,目前国内尚无针对车载抬头显示系统测量评价的标准出台。本文就近年来国内外关于抬头显示系统成像参数检测方法的技术发展进行了综述,并对未来的发展进行了展望。

The vehicle head-up display system can effectively reduce the traffic accident rate caused by the driver looking down at the meter,which will become an inevitable trend in the future development of vehicle-mounted instrument display.Since the head-up display forms a virtual image by means of projection,it is relatively difficult to measure the key parameters such as imaging quality and distance.At present,there is no standard for the measurement eval・uation of the vehicle head-up display system in China.In this paper,the technical development of imaging parameters detection methods for head-up display systems in recent years is reviewed,and the future development is prospected.
