Abstract: The road condition information in front of the vehicle can only be displayed in the dashboard or vehicle navigation 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 projection 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.
