Embodiment 1

[0039] figure 1 It is a process schematic diagram of a gate control method provided by an embodiment of the present invention, and the process includes the following steps:

[0040] S101: Determine the vertical distance between the user of the face and the gate according to the eye distance of the face in the collected image.

[0041] The gate control method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device may be a server or the like, or a gate controller or the like.

[0042] In order to control the gate, the electronic device needs to obtain the image corresponding to the collected gate channel. Specifically, the image can be obtained through the image acquisition device, which can be installed at the corresponding position of the gate independently of the electronic device, which is convenient The image is collected, and when the image is collected by the image collection device, the image is sent to the elec...

Embodiment 2

[0058] In order to determine the recognition area of ​​the image acquisition device corresponding to the gate, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, according to the field angle of the image capture device corresponding to the gate and the gate The distance between the gate and the adjacent gate is determined to determine the recognition area of ​​the image acquisition device at the vertical distance from the gate, including:

[0059] According to the first field of view angle of the image acquisition device corresponding to the gate, it is determined that in the first area corresponding to the first field of view, when the user with the face is at the vertical distance from the gate, the first acquisition area of ​​the image acquisition device;

[0060] According to the distance between the gate and the adjacent gate, determine the acquisition overlap area of ​​the image acquisition device when the gate is at the vertical...

Embodiment 3

[0077] In order to determine the recognition area of ​​the image acquisition device, on the basis of the above embodiments, in the embodiment of the present invention, according to the distance between the gate and the adjacent gate, determine the During the distance, the acquisition overlapping area of ​​the image acquisition device includes:

[0078] Determining a second area corresponding to the second field of view according to the second field of view of the image acquisition device corresponding to the adjacent gate;

[0079] According to the distance between the gate and the adjacent gate, determine the collection overlapping area where the first area overlaps with the second area when the gate is at the vertical distance.

[0080] In the embodiment of the present invention, when there is an adjacent gate on at least one of the left and right ends of the gate, according to the second field of view angle of the image acquisition device corresponding to the adjacent gate, t...

Abstract

The invention discloses a gate control method and device, equipment and a medium. According to the embodiment of the invention, the vertical distance between the user of the human face and the gate can be determined according to the eye distance of the human face in the acquired image, and the distance between the gate and the adjacent gate can be determined according to the field angle of the image acquisition equipment corresponding to the gate and the distance between the gate and the adjacent gate. According to the identification area of the image acquisition equipment, the distance between the gate machine and the adjacent gate machine is considered when the acquisition area of the image acquisition equipment is determined, so that the identification area is not overlapped with the identification area of the image acquisition equipment of the adjacent gate machine, and the anti-interference capability of the gate machine control method is improved.

Description

technical field [0001] The invention relates to the fields of face recognition and gate control, in particular to a gate control method, device, equipment and medium. Background technique [0002] The gate is a channel blocking device, which is used to manage the flow of people so that only one person can pass at a time. In order to facilitate the management of the flow of people and standardize the entry and exit of pedestrians, the use of gates is becoming more and more common. At present, gates are widely used in subways, high-speed rail, office buildings, communities, factories, tourist attractions, etc. [0003] With the continuous improvement of face recognition technology, face recognition gates that identify people's identities through image acquisition equipment have gradually replaced old-fashioned card swiping gates and fingerprint gates because of their high anti-counterfeiting, convenient verification, and fast passing speed. machine etc. [0004] In the prior...
