Embodiment 1

[0032] The embodiment of the present application can run on the control and alarm server or the monitoring platform, but is not limited thereto. figure 1 It is a flow chart of the method for deploying and controlling alarms based on object recognition according to Embodiment 1 of the present invention, as figure 1 As shown, the process includes the following steps S102 to S106.

[0033] In step S102, object tracking is performed based on the video stream, and multiple object pictures corresponding to the same object in the video stream are determined. In this embodiment, the object may be any object that needs to be controlled and alarmed, such as a human face, an object, a vehicle, and the like.

[0034] In at least one exemplary embodiment, step S102 may include:

[0035] Step S1022, detecting an object that first appears in the video stream;

[0036] Step S1024, using an object tracking algorithm to track the object in the video stream, and determine a plurality of objec...

Abstract

The invention provides a deploy and control alarm method and device based on object recognition, and a storage medium. The method comprises the following steps: performing object tracking based on a video stream, and determining a plurality of object pictures corresponding to the same object in the video stream; respectively matching the plurality of object pictures with a target object in a target object library to obtain one or more matching records; and screening the one or more matching records according to a screening condition, and carrying out deploy and control alarm based on the matching records meeting the screening condition, wherein the matching records meeting the screening condition comprise one of the following records: the matching records with the similarity ranked at thetop N in the one or more matching records, and the matching records with the similarity greater than a screening threshold in the one or more matching records. The problem of false alarm caused by thefact that a plurality of video image frames containing the same person are compared into different target deploy and control personnel is reduced, and the deploy and control alarm accuracy is improved.

Description

technical field [0001] The present invention relates to the field of image recognition, in particular to a control and alarm method, device and storage medium based on object recognition. Background technique [0002] With the development of new technologies such as deep learning and big data, human biometrics has been widely used. The face recognition technology that automatically judges the similarity of two face photos by computer, its effect has surpassed the effect of human eye recognition under certain conditions, and the application of face recognition technology in the field of video surveillance has become more and more extensive. [0003] In the field of video surveillance, the deployment and control alarm can be realized based on the results of face recognition, that is, the system analyzes the video stream of the bayonet in a specific key place, extracts the face, and compares it with the target control personnel in the control database in real time. When the si...
