The invention provides an electronic rearview mirror system based on an FPGA, and relates to the field of FPGA application. Comprising a camera module, an FPGA chip, a display screen and a DDR, the camera module is used for collecting surrounding environment information of a vehicle, and the FPGA chip comprises a data protocol conversion module, a VDMA module, a mean filtering module, an image equalization module, an edge detection increasing module, a DPU convolution module and a display screen driving module. Protocol conversion, filtering, image equalization, edge detection and DPU convolution are carried out on the videos around the vehicle collected by the camera module, and finally the display screen driving module outputs data streams to the display screen. According to the invention, the video display delay is controlled within 20ms, and smooth visual experience is provided for a driver. Meanwhile, the system can intelligently detect and sense special vehicles around the vehicle, and an optimal driving scheme is provided for a driver.

    本发明提供了一种基于FPGA的电子后视镜系统,涉及FPGA应用领域。包括摄像头模组、FPGA芯片、显示屏和DDR,摄像头模组用来采集车辆的周边环境信息,FPGA芯片包括数据协议转换模块、VDMA模块、均值滤波模块、图像均衡模块、边缘检测增加模块、DPU卷积模块、显示屏驱动模块,分别对摄像头模组采集的车周视频进行协议转换、滤波、图像均衡、边缘检测和DPU卷积,最终显示屏驱动模块将数据流输出到显示屏。本发明将视频显示延时控制在20ms以内,给驾驶人员流畅的视觉体验。同时该系统具备智能检测感知车周的特殊车辆,为驾驶人员提供最优的行车方案。
