Embodiment 1

[0073] A vehicle localization method based on parking lot, refer to figure 1 , which specifically includes the following steps:

[0074] 1100. The server acquires the license plate number of the target vehicle and the overall image of the vehicle.

[0075] Specifically, after the first camera and the second camera are arranged at the entrance of the parking lot, the server will obtain the front image of the vehicle through the first camera, and correspondingly, the server will also obtain the overall vehicle image of the target vehicle through the second camera.

[0076] Wherein, the vehicle front image includes the license plate of the target vehicle.

[0077] Moreover, after acquiring the front image transmitted by the first camera, the server will first obtain the license plate image from the front image through the license plate positioning algorithm, and then use the character recognition algorithm to process the above license plate image, thereby obtaining the license p...

Embodiment 2

[0141] The embodiment of the present application provides a parking lot-based vehicle positioning system 2, refer to Figure 4 As shown, the vehicle positioning system 2 includes:

[0142] The identification device 2100 obtains the license plate number of the target vehicle and the overall image of the vehicle;

[0143] an associating device 2200, configured to establish a mapping relationship for associating the license plate number with the vehicle overall image;

[0144] A feature extraction device 2300, configured to use a pre-trained learning model to process the overall image of the vehicle, and obtain feature information of the target vehicle;

[0145] A positioning device 2400, configured to obtain the location information of the target vehicle when the target vehicle is parked according to the feature information;

[0146] The data updating device 2500 is configured to update the parking space database of the parking lot where the target vehicle is located according...

Embodiment 3

[0161] Embodiment 3 of the present application further provides a storage medium containing computer-executable instructions, where the computer-executable instructions are used to execute a parking lot-based vehicle positioning method when executed by a computer processor, and the method includes:

[0162] Obtain the license plate number of the target vehicle and the overall image of the vehicle;

[0163] establishing a mapping relationship for associating the license plate number with the vehicle overall image;

[0164] Use the pre-trained learning model to process the full-view image of the vehicle, and obtain the feature information of the target vehicle;

[0165] According to the feature information, obtain the location information of the target vehicle when it is parked;

[0166] According to the location information and the mapping relationship, the parking space database of the parking lot where the target vehicle is located is updated.

[0167] The computer-readable...

Abstract

The invention relates to the technical field of vehicle data processing, in particular to a vehicle positioning method and system based on a parking lot and a storage medium. The method comprises thesteps of obtaining a license plate number and a vehicle full-view image of a target vehicle; establishing a mapping relationship for associating the license plate number with the vehicle full-view image; processing the vehicle full-view image by using a pre-trained learning model, and obtaining feature information of the target vehicle; obtaining position information of the target vehicle during parking according to the feature information; and updating a parking space database of the parking lot where the target vehicle is located according to the position information and the mapping relationship. The method can enable the parking lot to complete the confirmation of the vehicle parking position with a lower cost burden.

Description

technical field [0001] The present application relates to the technical field of vehicle data processing, and in particular, to a parking lot-based vehicle positioning method, system and storage medium. Background technique [0002] Due to the large scale and complex structure of parking lots in existing large shopping malls or stadiums, when drivers drive into such parking lots for the first time, it will cause great trouble for drivers to search for a car. [0003] In order to solve the driver's car search problem, the parking position of the driver's corresponding vehicle in the parking lot is generally located first, and then the driver is guided to the above-mentioned parking position by means of indicator signs or application navigation. [0004] In the related art, there are mainly two methods for determining the parking position of the above-mentioned vehicles. One is to arrange a camera next to the parking space for acquiring the front image of the vehicle; Set the...
