Introduction to License Plate Recognition System

The management of vehicles is an important aspect. Especially for special parking lots, courtyards, government agencies, and communities, all kinds of vehicles are required to be strictly managed in real time, their time of entry and exit should be strictly monitored, and all types of vehicles should be registered (including internal and external vehicles). Vehicles) and identification. In large-scale fields, there are many vehicles entering and exiting. For example, each vehicle must be manually judged, which is time-consuming, not conducive to management and inquiries, and the security work is difficult and inefficient. In order to improve this management mode that is not commensurate with modern parking lots, courtyards, government agencies, communities, etc., it is necessary to automate and intelligentize vehicle management as soon as possible, and manage it in the form of a computer network, so as to effectively control all vehicles at entrances and exits. Locally and accurately monitor and manage. The system is required to provide corresponding application software to realize the efficient and intelligent management of the camp.

Use the automatic license plate recognition algorithm of the video stream, or trigger by the sense of ground, to capture the vehicle and recognize the license plate. When the vehicle enters the entrance of the community, the automatic license plate recognition algorithm automatically captures the vehicle photo and recognizes the license plate number. The license plate number, color, and license plate Characteristic data, admission time information, etc. are transmitted and recorded, and vehicles can enter and exit the parking lot without barriers, providing users with a brand-new service mode.

The system automatically recognizes the number and license plate characteristics of the vehicles entering the community, verifies the legal identity of the user, automatically compares the blacklist database, automatically alarms, and can monitor and manage the entire parking lot, including entrance and exit management, internal management, collection and storage of data And the working status of the system, so that the administrator can monitor, maintain, count, query and print reports.
