Embodiment Construction

[0031] In the multi-angle face recognition method and system provided by the embodiments of the present invention, image information is obtained from multiple angles, and then the image information is detected and the face picture is collected, and by receiving the face picture and gesturing it Discriminate, select the frontal face picture, and finally extract the feature value of the frontal face picture within the collection cycle, perform face clustering processing and output, realize face collection without perception of the collected object without cooperation, through multi-angle collection In order to improve the collection rate of frontal faces in the case of relatively random face poses.

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0033] Embodiments of the present invention provide a m...

Abstract

The invention provides a method and system of recognizing the human face from multiple angles. The method comprises the following steps: acquiring image information from multiple angles, detecting the image information, collecting human face images from the image information, receiving the human face images, distinguishing the attitudes of the human faces, selecting front human face images, extracting the feature values of the front human face images in the collection period, classifying the human faces, and outputting. The human face images of the collected object can be collected under the condition that the collected object does not know and does not need to cooperate, and the front human face image collection rate can be improved by collecting from multiple angels under the condition that the attitudes of the human faces change randomly.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a multi-angle face recognition method and system. Background technique [0002] Today, face recognition technology is gradually applied to video security monitoring systems, and the premise of its application is face collection. The collection of frontal faces is the basis of the application of face recognition technology, but in reality, the posture of people is very random. In security checks, immigration and other occasions, the posture of the collected objects can also be forced, but in public cultural facilities Places, such as museums, art galleries, libraries, etc., cannot force the audience to cooperate with the collection, and in the actual application of the video security monitoring system, the hidden collection is often implemented, and the collection object is not perceived, so the posture of the collection object is uncontrollable. The current fac...
