Abstract

The invention discloses a face recognition method and a device, and an establishment method of a face detection library. The method comprises the following steps: acquiring image information of a target object; extracting facial features of a face in the image information; matching the face feature with at least one preset face feature in a face detection library, and determining a preset face feature successfully matched with the target object, the face detection library comprising a preset face feature of the invited object and a preset face feature of an object detected in a preset area; and obtaining the identity information of the successfully matched preset facial features to obtain the identity information of the target object. The technical problem that in the prior art, face recognition is conducted on the target object, and the recognition precision is low is solved.

Description

technical field [0001] The present application relates to the field of face recognition, in particular, to a face recognition method and device, and a method for establishing a face detection library. Background technique [0002] In the field of video conferencing, in order to recognize the faces of the people participating in the meeting, it is necessary to establish facial feature data in advance. However, in the prior art, only the people in the meeting invitation are put into the face feature database. In the actual video conference, many participants are not the inviters of the video conference, but are temporarily pulled into the video conference. These people are not in the pre-designed face feature database, which leads to the failure of face recognition in the video conference. Put all the personnel in the company into the face feature database. In the case of a large company, thousands or even tens of thousands of people will join the face feature database, which ...
