摘要
本文以STM32F407单片机为核心,设计了一种车载后视镜智能判距系统,该系统运用图像传感器对后视镜视距内的场景进行捕捉,对其中运动的物体进行分析,实现了识别车辆后方障碍物与本车距离并在后视镜中实时显示等功能,从而为新手驾驶员提供行驶及变道的依据。简要介绍了该系统总体结构及工作原理,详细阐述了该系统的硬件设计和软件设计,并设计实车测试实验验证了该系统的可靠性。
In this paper, STM32 F407 single-chip microcontroller(MCU) is used as the core to design an intelligent distance determination system for vehicle rearview mirror. The system uses image sensor to capture the scene within the sight distance of the rearview mirror, analyzes the moving objects, realizes the functions of recognizing the distance between the obstacles behind the vehicle and the vehicle and displaying the distance in the rearview mirror in real time, so as to provide the basis of driving and lane changing for novice drivers. The overall structure and working principle of the system are briefly introduced, the hardware design and software design of the system are described in detail, and the reliability of the system is verified by a real vehicle test.
