在雨天，传统外后视镜和车窗玻璃极易受到雨水滴挂的影响，常常让驾驶员无法看清后方车辆。此外，夜间行驶时，光线灰暗，也常常给驾驶员带来诸多的不便。而电子外后视镜就完美的解决了这些难题，通过摄像头和显示屏结合的方式，不仅能提升车辆后方以及与其他车辆相邻区域的可见度，还能减少风噪声并扩大视野。On rainy days, traditional exterior mirrors and window glass are highly susceptible to raindrops, often making it impossible for drivers to see the vehicles behind them. In addition, when driving at night, the light is dim, which often brings a lot of inconvenience to the driver. The electronic exterior mirror perfectly solves these problems. Through the combination of camera and display, it can not only improve the visibility behind the vehicle and adjacent areas to other vehicles, but also reduce wind noise and expand the field of view.
然而，电子外后视镜系统属于电气系统机构，包括摄像头、视频处理控制器和显示屏摄像头将采集到的后视影像传递至视频处理控制器中进行处理（如图像信号的转换等），视频处理控制器将处理的信号传递至显示屏，在显示屏上显示后视影像。后视影像在处理传输过程中，使得在显示屏成像时间和采集到的后视影像时间存在时间差，即显示屏成像显示时间延迟，如果延迟时间超过一定阈值，这样电子外后视镜出现延时失效，可能给用户错误的视频指示信息，从而导致用户错误变道与与邻车发生碰撞导致严重伤害，而电子外后视镜系统的时间延迟主要为视频处理控制器处理视频信号部分，所以监控视频处理控制器部分的延时就能有效对电子外后视镜的延时进行监控。However, the electronic exterior rearview mirror system belongs to the electrical system mechanism, including the camera, the video processing controller and the display screen camera to transmit the captured rearview image to the video processing controller for processing (such as image signal conversion, etc.), video The processing controller transmits the processed signal to the display screen, where a rear view image is displayed on the display screen. In the process of rearview image processing and transmission, there is a time difference between the imaging time of the display screen and the time of the rearview image collected, that is, the imaging display time of the display screen is delayed. If the delay time exceeds a certain threshold, the electronic exterior mirror will be delayed. If it fails, it may give the user wrong video indication information, thus causing the user to change lanes by mistake and collide with the adjacent car, resulting in serious injury. The time delay of the electronic exterior mirror system is mainly for the video processing controller to process the video signal part, so monitoring The delay of the video processing controller part can effectively monitor the delay of the electronic exterior rearview mirror.

具体实施方式Detailed ways
下面结合附图和具体实施方式对本发明作进一步详细说明。The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
参见图1，一种电子外后视镜延时监控报警系统，包括视频处理控制器、设置在车外的摄像头和设置在车内的显示屏，所述摄像头用于采集后视影像，所述视频处理控制器包括视频解码芯片、图像处理芯片和视频解码芯片，所述视频解码芯片和摄像头连接，用于接收后视影像的视频信号并对视频信号进行解码，所述图像处理芯片与视频解码芯片连接，以对解码后的视频信号进行渲染处理，所述视频编码芯片与所述图像处理芯片连接，以对渲染后的视频信号进行编码，所述显示屏和视频编码芯片连接，以对编码后的视频信号进行显示。Referring to FIG. 1, an electronic exterior rearview mirror delay monitoring and alarm system includes a video processing controller, a camera set outside the car, and a display screen set inside the car, the camera is used to collect rear-view images, and the The video processing controller includes a video decoding chip, an image processing chip and a video decoding chip. The video decoding chip is connected to the camera and is used for receiving the video signal of the rear view image and decoding the video signal. The image processing chip is connected to the video decoding chip. The chip is connected to render the decoded video signal, the video encoding chip is connected to the image processing chip to encode the rendered video signal, and the display screen is connected to the video encoding chip to encode the The following video signal is displayed.

这样可以根据用户驾驶习惯或者要求，在合理范围内实时调整设定阈值，以保证在行车安全的同时，提高用户的体验感。In this way, according to the user's driving habits or requirements, the set threshold can be adjusted in real time within a reasonable range, so as to ensure driving safety and improve the user's experience.
具体实施时，所述设定阈值小于等于200ms。During specific implementation, the set threshold is less than or equal to 200ms.
在实际应用时，可以根据需要设定具体的阈值，如果对安全性要求不是特别高，其阈值也可以设定为大于200ms。In practical applications, a specific threshold can be set as required. If the security requirements are not particularly high, the threshold can also be set to be greater than 200ms.
具体实施时，所述MCU芯片与图像处理芯片连接，便于当时间差大于MCU芯片设定阈值时，以对图像处理芯片进行故障处理。During specific implementation, the MCU chip is connected to the image processing chip, so that when the time difference is greater than the threshold value set by the MCU chip, the image processing chip can be processed for failure.
比如，当时间差大于MCU芯片设定阈值时，图像处理芯片可以自动进行重启，以应对故障。For example, when the time difference is greater than the threshold set by the MCU chip, the image processing chip can automatically restart to deal with the failure.
