Abstract

The present invention relates to an automatic parking status and license plate recognition system that determines the location and parking status of a parked vehicle by analyzing image data acquired from a camera that photographs a plurality of parking spaces within a parking area. More specifically, the invention relates to an automatic parking status and license plate recognition system comprising: at least one camera that photographs a parking area in which a plurality of parking spaces are arranged; a processing unit that pre-sets a parking area and a detection area based on the camera’s shooting angle and the arrangement of the parking spaces on the image data acquired through the camera, and determines the parking status of the vehicle through the arrangement ratio of the vehicle placed in the set parking area and detection area; and a number recognition unit that recognizes the license plate of a vehicle parked in a parking space.

Description

Automatic Parking Status and License Plate Recognition System The present invention relates to a parking status and automatic license plate recognition system, and more specifically, to a parking status and automatic license plate recognition system that analyzes image data acquired from a camera capturing multiple parking spaces within a parking area to determine the location and parking status of a parked vehicle and recognizes a license plate. In modern society, with the increase in the number of vehicles, the efficient management of parking spaces is emerging as a critical challenge. Particularly in large or complex parking lots, accurately recognizing and managing the parking status of vehicles has become an essential element for enhancing operational efficiency and providing user convenience. Traditional parking management systems primarily use methods to check parking status through sensors installed in parking spaces or systems that detect vehicle entry and exit, but these systems have the following problems. First, it is difficult to accurately determine the parking status in abnormal situations, such as when a vehicle is only partially positioned in a parking space or when double parking occurs. Additionally, the installation and maintenance costs of physical sensors are high, and the reliability of the entire system may be compromised in the event of a sensor failure. Furthermore, situations may arise where the existing system fails to make accurate judgments when a vehicle is parked at various angles or when parking spaces are arranged asymmetrically. To overcome these limitations, camera-based parking recognition systems have emerged; however, existing camera-based systems can experience recognition errors depending on the shooting angle or the layout of the parking spaces. In particular, in complex parking environments, there were limitations in accurately recognizing the vehicle's parking status from captured video, which sometimes led to misrecognition or a failure to accurately assess the parking situation.
