Embodiment Construction

[0017] The overall steps of a method for judging a person's identity from a video according to the present invention are as follows:

[0018] According to the walking trajectory of the judged person, the monitoring video data of multiple different video monitoring points is obtained; the image information of the judged person in one or more consecutive frames of the monitoring video data image frame is obtained; Threshold image frames, and extract the judged personnel image information according to the obtained image frames; comprehensively compare the multiple frames of image information extracted with each other, and select the optimal image information to combine with each other to form the final extracted personnel image information; the extracted final personnel image The information is submitted to the face recognition system for storage and comparison.

[0019] Described personnel image information comprises human face basic information, human face attitude information ...

Abstract

A video personnel identification method includes establishing a personnel image information registration database; according to the walking trace of an identified person, acquiring monitoring video data of different video monitoring points; acquiring the personnel image information of the identified person according to one frame or multiple continuous frames of the monitoring video data images; according to an image frame fuzzy threshold, acquiring image frames larger than the threshold, and extracting the personnel image information of the identified person according to the acquired image frames; comparing the extracted multiple frame image information comprehensively, and selecting optimal image information to combine so as to acquire final extracted personnel image information; submitting the final extracted personnel image information to a face registration database to compare or register and store. The method has the advantages that the defects that according to the prior art, the personnel identification error rate is high, efficiency is low and persons with changed clothes or shielded faces cannot be identified are solved.

Description

technical field [0001] The invention belongs to the field of face recognition, and in particular relates to a method for judging a person's identity from a video. Background technique [0002] Face recognition is not only a research hotspot in the field of artificial intelligence, but also has important practical significance in the field of public security. [0003] With the continuous development of technology, video surveillance equipment is generally installed in public places to monitor public safety. In the current video surveillance field, traditional cameras are gradually being replaced by a new generation of embedded network cameras. Compared with traditional cameras, network cameras can convert analog video signals into digital video signals, and realize remote monitoring through the network. For face recognition, video surveillance uses some features of the face, such as facial features, to recognize the face. [0004] The existing face recognition method is to...
