Abstract

The invention discloses a face recognition method and device, equipment, and a clocking-in method, device and system. The face recognition method comprises the steps that a face picture is subjected to face deflection angle detection to obtain a side face angle; the face picture is subjected to feature recognition to obtain side face features; front face features corresponding to the front face ofa figure in the face picture are obtained through a conversion function among the side face angle, the side face features and the front face features on the basis of the side face angle and the sideface features; and the front face features are compared with front face bottom library features of all users stored in a database, and the user identity corresponding to the face picture is determined. According to the face recognition method, a user side face image can be subjected to feature conversion to obtain the front face features for user identity recognition, the identity can be recognized without the need of providing the front face picture of the user, the recognition efficiency is improved, a large number of side face pictures do not need to be stored in the database, the storage space is saved, the feature comparison time is shortened, the number of pictures needing to be compared is decreased, and the accuracy of side face recognition is improved.

Description

technical field [0001] The present application relates to the technical field of face detection and recognition, in particular to a face recognition method, device, equipment and check-in method, device and system, and more specifically, to a face recognition method for improving the accuracy of side face recognition. Recognition method, device, equipment and check-in method, device and system. Background technique [0002] Strictly standardizing employee clock-in and attendance is an important guarantee for modern enterprises and institutions to improve management efficiency. With the development of image analysis technology and artificial intelligence technology, products based on face recognition for attendance check-in are more and more widely used. Face recognition is a biometric identification technology that authenticates people's facial feature information. The current face check-in technology is firstly based on the business scenario, collecting the front face ima...
