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.

摘要： 我国交通事故整体数量逐年上升，A 柱盲区是造成交通事故的主要原因之一。国内 A 柱盲区测量系统存在造价高、对车体结构影响大等问题，针对这些问题，文章提出一种新型 车载智能 A 柱盲区显示系统。该系统通过视觉传感器和视线追踪设备等一系列检测装置获取 驾驶员头部位置和注视点等信息，结合 A 柱位置和结构，智能地调整覆盖在 A 柱上显示屏的 显示画面，近似地达到使 A 柱相对于驾驶员透明化的效果，从而有效地减少 A 柱盲区造成的 交通事故的发生概率。
