摘要：为了避免无红绿灯、有障碍物交叉路口或单弯道路口发生交通事故的情况，实现经过此类路口时，人们能够根据路口设备上的提示直观地了解到待行驶路口视野盲区的情况，避免在转弯时出现紧急刹车、避让而造成严重的交通事故。所研究的指示设备用STM32做主控器，Openmv模块进行识别处理，超声波模块用来测距，LED显示表达盲视野情况，SD卡用于视频保存，采用太阳能充电板+锂电池的电源结构。该设备可让驾驶人与行人了解到视野盲区的状态，起到警示作用，还能为紧急事故提供视频监控数据，实时还原事故场景。24小时工作，避免偶然情况的发生。

Abstract: In order to avoid the intersection traffic lights have obstacles or single curve intersection traffic accident happens, implemented through this intersection, people can according to the prompts on the intersection equipment intuitive understanding of the vision to stay along road blind area, avoid emergency brake on corners, avoidance and cause serious traffic accident.The indicator device studied uses STM32 as the main controller, Openmv module for identification processing, ultrasonic module for ranging, LED display to express blind field, SD card for video storage, and the power structure of solar charging panel + lithium battery. The device can alert drivers and pedestrians to the state of blind areas of vision. It can also provide video surveillance data for emergencies and restore the scene of accidents in real time. Work 24 hours a day to avoid accidents. The whole system is closely connected, simple in structure, reliable and practical.
Key words: blind area of vision; Openmv; ranging
