摘　　要：传统内后视镜采用光学反射的方式为驾驶员提供后方视野,但是由于车体结构的特点, C柱和后排靠枕都会带来极大的视野盲区。本文提出一种基于嵌入式系统的3路流媒体后视系统设计,该系统采用Ambarella A9AQ图像处理芯片,能够实时采集、处理分别布置在左、右外后视镜和车辆后方的3路图像,并将图像传输到流媒体后视镜上。实际路试效果表明整套系统运行流畅,满足实时性和清晰度的要求,能够有效地提升视野范围,降低车辆侧、后方视野盲区,提高安全驾驶系数。The traditional inner rearview mirror provides the driver with rear vision by optical reflection,but because of the characteristics of the car body structure,C pillar and rear pillow will bring great blind area of vision. This article presents a three-channel streaming media rearview system based on embedded system. The system uses Ambarella A9AQ image processing chip,which can collect and process three-channel images in real time,which are arranged in the left and right rearview mirrors and the rear of vehicles respectively,and transmit the images to the rearview mirrors of streaming media. The actual road test results show that the whole system runs smoothly,meets the requirements of real-time and clarity,can effectively improve the visual field range,reduce the blind area of vehicle side and rear visual field,and improve the safety driving coefficient.
