Abstract

The invention discloses a method for deduplication and identification of personnel, a storage medium and computer equipment, and relates to the technical field of image processing. The invention can effectively distinguish personnel from strangers who are on the list or not on the list by maintaining a cache queue T De-duplication recognition; using the overlapping degree of the face frame position and the similarity double threshold of the face algorithm, on the one hand, it can solve the problem of personnel lost due to video decoding frame drop or low detection rate of the face algorithm, effectively reducing When people in the list pass, the additional wrong passage records are generated; on the other hand, the double threshold of similarity of the face algorithm is used to achieve effective deduplication of both static and non-static targets; whether it is the overlapping degree of the face frame position or The similarity calculation of the face algorithm, the calculation process does not require high computing power, and can run smoothly on most devices.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a method for deduplication and identification of persons, a storage medium and computer equipment. Background technique

[0002] With the maturity and development of face recognition technology, face recognition is more and more widely used in intelligent access control systems, and many corresponding face recognition access control systems have appeared on the market. However, when people walk in front of the camera, they often capture more than one or two face photos, so the face recognition smart access control system will generate many face image records that are not much different, but belong to the same person. To this end, it is necessary to use a deduplication algorithm to minimize such records. At present, the main deduplication algorithms for face images mainly include deduplication methods based on traditional image features (such as color histogram, LBP hist...

Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] like Figure 1-Figure 3 A method for deduplication and identification of personnel is shown, comprising the following steps:

[0047] S1. Create an empty cache queue , cache queue The queue element data contains face images , face frame position , face pose score , face code , classification flag and the second-level timestamp when the element was added ;

[0048] S2. Take out the decoded picture from the network camera in a loop; assumi...
