Embodiment Construction

[0015] 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 persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] Examples, see figure 1 , the present invention provides a technical solution: a search method for sub-databases in order to improve the recognition speed after the face pictures are collected by a camera. Each group has its own independent passerby database. All stores in the same city share a member database. The passerby database is used to save the face information of ordinary passers-by. Marked as members, employees, blacklists and other special pe...

Abstract

The invention discloses an optimization method based on a face recognition sub-library strategy, and the method comprises the following steps: (1), building group information and city information after a merchant accesses; step (2), the camera uploads a captured picture to a platform, and picture quality judgment is carried out; step (3), after picture detection is compliant, the platform analyzes related information, firstly queries a city face database to which the platform belongs, and calls a face recognition algorithm to carry out face recognition in the city face database; if the matching is not successful, performing face recognition detection in a store to which the camera belongs; and step (4), after face recognition detection, if matching is not successful, storing the feature value of the current face picture in a store library for next recognition. According to the invention, people with special identities can be quickly retrieved and matched in a city range through the city shared face database; the passerby library is divided, the capacity of the special identity person library is reduced, and the recognition efficiency of the special identity person is improved.

Description

technical field [0001] The invention relates to the technical field of video communication, in particular to an optimization method based on face recognition sub-database strategy. Background technique [0002] With the continuous popularization of security cameras and the continuous improvement of their intelligence, face recognition is used more and more in this type of product. However, due to the influence of some factors such as light and angle, false recognition often occurs in the camera. As well as problems such as low recognition accuracy, the existing solutions on the market cannot deal with this misidentification problem very well, and an optimization solution is needed to ensure the accuracy and user experience of the camera for face recognition. In view of this, this solution discloses a method for optimizing the speed of face detection in face recognition. Contents of the invention [0003] The purpose of the present invention is to provide an optimization m...
