Abstract

Vehicle augmented reality head-up display (AR-HUD)，its core technology derived from aviation application. Through the virtual image optical projection system, AR symbols, such as navigation arrows, lane marks, pedestrian warning, etc. and instrument panel information comprised travel speed, engine revolution speed, and so on are projected to the front windshield glass and displayed on the external real visual fusion with proper location, which may help the driver to avoid looking down on the panel frequently and uninterrupted watch the road ahead. With the aid of augmented reality technology, the real-time vehicle operation and guidance can be acquired, which significantly enhance driving safety, and effectively reduce the burden of driving. AR-HUD is an important technology direction of intelligent network connection in automobile industry. Based on large-scale commercial application, this paper summarizes definition, classification, development history, domestic and foreign status quo and development trend of AR-HUD. From the aspects of optics, background stray light, freeform surface windshield, structural volume heat dissipation and AR software, the technical challenges of vehicle AR-HUD are pointed out. Combined with R & D experience and the project practice, the corresponding measures are given. This paper has an important reference significance for the mass production of vehicle AR-HUD technology.
