Problems solved by technology
[0006] The gate control system requires people to look at the camera. Only when they face the camera can they capture the face, perform identification and authentication, and track the person at the moment. Judging the number of the gate that is about to pass according to the position of the person standing in the screen, and controlling the gate to open, the judgment accuracy is low

The invention provides a gate control method, device and system, and belongs to the technical field of security and protection. The gate control method comprises the steps of: obtaining images of a target area captured by a plurality of cameras; analyzing the image obtained by at least one camera to judge whether face information that meets preset conditions is present in the image; when the faceinformation that meets preset conditions is present, cooperatively tracking a movement trajectory of a person object corresponding to the face information by the plurality of cameras; and controllingthe opening and closing of a gate according to the movement trajectory. Compared with the prior art, the gate control method provided by the invention has the advantages of starting face recognition and identity verification when a person walks toward the gate, and when the person reaches the vicinity of the gate, the gate can be opened, and no traditional distance sensor is needed to start and stop the gate, so that the traffic efficiency is high; and moreover, the gate by which the person is about to pass is accurately controlled by the movement trajectory, thereby not only ensuring the traffic efficiency of the gate, but also improving the opening accuracy of the gate.
Description
Technical field [0001] This application relates to the field of security technology, and in particular to a gate control method, device and system. Background technique [0002] With the development of image processing technology, face recognition has been widely used in identity verification, for example, face recognition gates. The face recognition gate control system in the prior art mainly includes the following two modes. [0003] 1. Install an external device on a channel with a gate. This external device includes a camera, a face recognition system and a distance sensor. When a person approaches the external device, the distance sensor is triggered. Turn on the camera to obtain the face image. The recognition system analyzes the acquired facial images, verifies the identity of the person, and controls the gate to open after passing the verification. [0004] The gate control system triggers the face recognition and identity verification processing only when a person approach...
