Based on OpenMV module,a license plate recognition 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.
