Abstract: The overall number of traffic accidents in China is increasing year by year, and the A-pillar blind area is one of the main causes of traffic accidents. There are some problems in the domestic A-pillar blind area measurement system, such as high cost and great impact on the car body structure. Aiming at these problems, a new on-board intelligent A-pillar blind area display system is proposed in this paper. The system obtains the information of the driver's head position and fixation point through a series of detection devices such as visual sensors and line of sight tracking equipment. Combined with the position and structure of the A-pillar, the system intelligently adjusts the display screen covered on the A-pillar to approximately achieve the effect of making the A-pillar transparent to the driver, so as to effectively reduce the probability of traffic accidents caused by the blind area of the A-pillar.
