一种车载智能A柱盲区显示系统

A-pillar on-board Blind Area Intelligent Display System

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。

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.
