针对传统的红外夜视系统在仪表盘或车载导航上显示前方路况画面时，驾驶员低头观看而存在安全隐患的问题，提出一种将前方路况信息投射于前风挡全息投影膜上的车载投影方案设计。该方案将红外夜视摄像头采集的视频信号经过处理，投射到前风挡全息投影膜上，使驾驶员在夜间及大雾等不良天气情况下能轻松地观测到前方道路信息，对潜在危险做出快速及时的反应，避免交通事故，提高行驶安全。

The road condition information in front of the vehicle can only be displayed in the dashboard or vehicle naviga-tion device leading to the driver bowing to watch. For the security risk in the traditional infrared night vision system, a novel vehicle projection design is proposed, which will project the road condition information onto the holographic projec-tion film of the front windshield. In this proposed scheme, the video signal captured by the infrared night vision camera is sampled into FPGA device first, and then projected onto the holographic projection film so that the driver can easily observe the front road condition at night as well as in bad weather conditions, such as foggy environment. Rapid response will be made timely. Driving safety will be improved and traffic accident can be efficiently avoided.
