specific Embodiment 1

[0044] The parking space positioning logic of the three-dimensional garage based on license plate recognition is based on the premise that the license plate of the empty parking space sign is placed on the parking space of the three-dimensional garage, for example, Shanghai KB1111, Shanghai KB2222, Shanghai KB3333, Shanghai KB4444 are placed on the parking space of the three-dimensional garage. , Shanghai KB5555, when the system recognizes that the current license plate is Shanghai KB1111, Shanghai KB2222, Shanghai KB3333, Shanghai KB4444, Shanghai KB5555, it means that there is no vehicle parked in the current parking space, otherwise, when the recognized valid license plate is not these The license plate indicates that there is a car parked in the parking space, and the information of the parking space and the license plate information of the parked vehicle are recorded.

[0045] First initialize the parking space data, determine the current video surveillance parking space n...

specific Embodiment 2

[0046] According to the description of Embodiment 1, an empty parking space sign will be placed on the parking spaces in the three-dimensional garage. When the license plate is detected, it is determined that the parking space is empty. On the contrary, when the recognized license plate is another valid license plate, it is determined that there is a car parked in the parking space and the license plate information is recorded.

specific Embodiment 3

[0047] According to the description of Embodiment 1, after the user parks the car in the three-dimensional garage, the system locks and records the parking space information of the user's vehicle through the three-dimensional garage parking space positioning method based on license plate recognition. The warning light in front of this group of parking spaces will be red, indicating that no more parking is allowed, and on the contrary, when it is green, it means parking is possible.

[0048] In summary, this three-dimensional garage parking space positioning method based on license plate recognition has improved the speed and accuracy of license plate recognition, increased the capacity and revenue of the parking lot, and improved the technological content of operation and maintenance, logistics, and security management of the parking park or parking lot. , can provide a lot of convenience for the managers of parking parks or sites, and also save more costs for the developers of...

Abstract

The invention discloses a stereo garage parking space positioning method based on vehicle license plate recognition. The method comprises the steps that parking space data is initialized, the parkingspace data is uploaded, an uploaded parking space state is judged, and the like. The speed and accuracy of the vehicle license plate recognition are improved; the capacity and income of a parking lotare improved; the operation and maintenance, logistics and guarantee management technology content of a parking zone or the parking lot is improved; a lot of convenience can be provided for managers of the parking zone or the parking lot; more costs are reduced for developers of the parking park or the parking lot; while the costs are reduced, the income of the parking zone or the parking lot is improved; the investment cost and the management cost of the parking zone or the parking lot are reduced; and the parking experience of users and the management experience of the managers are improved.

Description

technical field [0001] The invention relates to the technical field of parking management, in particular to a three-dimensional garage parking space positioning method based on license plate recognition. Background technique [0002] Now there are a variety of license plate recognition technologies to achieve the purpose of license plate recognition, but each has its own advantages and disadvantages in the speed of license plate recognition and the accuracy of license plate recognition, and this technology is a dynamic video or static image of the vehicle. , Pattern recognition technology for automatic license plate color recognition. Its hardware foundation generally includes triggering equipment, camera equipment, lighting equipment, image acquisition equipment, and a processor for recognizing license plate numbers, etc., and its software core includes license plate positioning algorithms, license plate character segmentation algorithms, and optical character recognition a...
