摘　　要：基于OpenMV模块,设计了一种车牌识别系统。该系统以STM32H7系列单片机为主控芯片,利用OV5640摄像头模组采集原始车牌图像,通过Micro Python语言算法对图像进行预处理、定位车牌、分割字符和模板匹配识别,最终通过QVGA屏幕和串口通信实输出车牌信息。本系统识别效果较好且所需芯片算力资源较少,适用于低成本、高效率的嵌入式平台。Based on OpenMV module,a license plate rec ognition system is designed.The system uses STM32H7 series microcontroller as the main control chip,uses OV5640 camera module to collect the original license plate image,and uses Micro Python language algorithm to preprocess the image,locate the license plate,partition characters and template matching recognition,and finally realizes the license plate information output through QVGA screen and serial communication.This system has a good recognition effect and requires less chip computing resources,which is suitable for the use of low cost and high efficiency embedded platform,and provides support for further realization of intelligent vehicle management.
