Embodiment 1

[0027] This embodiment provides an open parking charging method based on image recognition. When the open parking management device recognizes that the vehicle enters the warehouse, it will capture the vehicle entering the warehouse, obtain a group of captured pictures, and then start the present invention An open parking charging method based on image recognition, the method specifically includes:

[0028] S1, carry out license plate recognition on a group of pictures (N pieces) collected respectively, if recognize license plate, then enter S2, if not recognize license plate, then enter S3.

[0029] Among them, the license plate recognition can use the traditional character segmentation and character recognition strategy to recognize the license plate in the picture. The detected license plate is segmented by vertical projection or connected area analysis method, and then the segmented single character is used. lbp+ Algorithms such as svm, gabor+svm or convolutional neural ne...

Embodiment 2

[0063] The embodiment of the present application also includes an open parking metering device based on image recognition, including:

[0064] The storage picture capture module is used to capture the vehicles in the parking space when they are stored in and out of the storage. And send the captured pictures to the license plate recognition module for recognition.

[0065] The license plate recognition module performs license plate recognition on a group of pictures (N pieces) collected. If the license plate is recognized, it will be sent to the whole license plate confidence judgment module. If the license plate is not recognized, it will be sent to the vehicle identification. module for further discrimination.

[0066] Confidence degree judgment module of the whole license plate: through the license plate recognition module, the confidence degree of the recognized license plate is judged as follows. If the following two conditions are met at the same time, the picture is ma...

Abstract

The invention discloses an open parking billing method based on image recognition. The technical solution of the invention is mainly divided into two processes of vehicle storage and vehicle departure. Collect a group of pictures, and then send them to the storage process to judge whether the parking space is occupied by a vehicle. If there is a vehicle, mark this parking space as storage, otherwise continue to wait; if the status of the parking space is In-warehouse status, that is, vehicles are occupied, and the images collected by the vehicle image acquisition equipment are sent to the out-of-warehouse process for identification. The out-of-warehouse process is divided into two types: the out-of-warehouse process of automatic warehousing vehicles and the out-of-warehouse process of manual identification of warehousing If it is judged to be out of the warehouse, calculate the time occupied by the vehicle for billing and generate a bill and send it to the owner, otherwise continue to wait. Also disclosed is an image recognition-based open parking charging device. The method and device provided by the invention can effectively improve the efficiency of parking space management in open parking spaces and improve user experience.

Description

technical field [0001] The invention relates to an image recognition-based open parking charging method and device. Background technique [0002] At present, based on closed parking lots, most of them have their own vehicle entry and exit management software. Through simple license plate recognition technology, the entry and exit time of vehicles can be accurately obtained, and the parking fee can be calculated. However, fare billing in open scenarios such as roadsides has always been a problem. At present, most of them use manual charging, which is inefficient and requires a lot of labor. The present invention proposes an open parking billing method and device based on image recognition. A vehicle image acquisition device is installed near each parking space on the roadside in advance. This device can sense the entry and exit of vehicles, and combine analysis and snapshot The license plate and other information in the image can eventually automatically generate a parking b...
