Embodiment 1

[0025] figure 1 It is a flow chart of a parking space state detection method in Embodiment 1 of the present application. The embodiment of the present application is applicable to the situation of identifying the use state of a parking space equipped with a camera. The method is executed by a parking space state detection device, and the device passes Realized by software and / or hardware, and specifically configured in an electronic device, the electronic device may be an image acquisition device.

[0026] Such as figure 1 A parking space state detection method shown includes:

[0027] S110. Acquire the parking space image of the target parking space, and identify whether there is a reference object image in the parking space image; wherein, the reference object is set in the target parking space.

[0028] Exemplarily, the reference object may be a wheel chock, so that the technical solution of the embodiment of the present application can be used to detect the state of the ...

Embodiment 2

[0039] figure 2 It is a flow chart of a parking space state detection method in Embodiment 2 of the present application. The embodiment of the present application is optimized and improved on the basis of the technical solutions of the above-mentioned embodiments.

[0040] Further, the operation "determine the current parking space state of the target parking space according to the symmetry of the reference object image" is refined into "determine the symmetric reference of the reference object image; wherein, the symmetric reference includes the symmetry center and / or axis of symmetry; determine the current parking space state of the target parking space according to the symmetry reference", so as to improve the determination mechanism of the current parking space state.

[0041] Such as figure 2 A parking space state detection method shown includes:

[0042] S210. Acquire a parking space image of the target parking space, and identify whether there is a reference object...

Abstract

The embodiment of the invention discloses a parking space state detection method, device and equipment, and a storage medium. The method comprises the steps: obtaining a parking space image of a target parking space, and recognizing whether a reference object image exists in the parking space image or not, wherein a reference object is arranged in the target parking space; and if so, determining the current parking space state of the target parking space according to the symmetry condition of the reference object image, wherein the current parking space state is an idle state or an occupied state. According to the technical scheme provided by the embodiment of the invention, the current parking space state of the target parking space is identified by using the symmetry of the reference object image in the parking space image so that the situation that the parking space state is identified mistakenly due to the fact that a license plate is shielded or a parking vehicle is not equipped with the license plate when the parking space state is detected through the license plate in the prior art is reduced; and therefore, the error recognition rate of the parking space state is reduced, the parking space state recognition precision is improved, and the reliability and the user satisfaction of a parking lot management system are improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to a parking space state detection method, device, equipment, and storage medium. Background technique [0002] With the development and application of security monitoring technology in the parking lot industry, the new parking lot management system has been widely accepted and used in the market. [0003] Generally, the parking lot management system will collect images of the parking spaces, and recognize the license plates in the collected images, determine whether the parking spaces are occupied or free according to the recognition results of the license plates, and indicate the status of the parking spaces through the indicator lights , to guide the owner to stop. [0004] However, when the license plate of the parked vehicle in the parking space is blocked or the parked vehicle does not have a license plate, there will be situations whe...
