License plate recognition method and device, storage medium and electronic equipment

Abstract

The invention provides a license plate recognition method and device, a storage medium and electronic equipment, and the method comprises the steps: determining a correction weight corresponding to each vehicle license plate character in a current vehicle license plate if the current vehicle license plate recognized by image recognition equipment does not match each on-site license plate when the vehicle is driven out of a parking lot, which is used for constructing a first target vector; determining a target license plate character corresponding to each on-site license plate character in each on-site license plate so as to determine a correction weight corresponding to each on-site license plate character for constructing a second target vector corresponding to each on-site license plate; determining the similarity between each second target vector and the first target vector; and taking the on-site license plate corresponding to the second target vector with the highest similarity with the first target vector as the license plate corresponding to the vehicle. By applying the method of the invention, the license plate corresponding to the vehicle can be determined in each on-site license plate, and the automatic management of the vehicle can be ensured. Manual handling procedures are not needed, and time and resources can be saved.

Description

technical field [0001] The invention relates to the technical field of vehicle management, in particular to a license plate recognition method and device, a storage medium and electronic equipment. Background technique [0002] With the development of image recognition technology, in the process of vehicle entry and exit management in the parking lot, image recognition equipment is usually used to identify the license plate of the vehicle, and automatic management is realized based on the recognized license plate. [0003] In the current automated management process, the license plate of the vehicle is usually recognized by the entry recognition device at the entrance of the parking lot, and the entry information of the vehicle is recorded based on the license plate recognized by the entry recognition device, while at the exit of the parking lot The vehicle's license plate is re-identified by the exit recognition device, and the entry information of the vehicle is matched ba...
