Image pickup device face tracking method and system and electronic equipment

Abstract

The invention provides a camera device face tracking method and system and electronic equipment, and relates to the technical field of biological feature recognition. The method comprises the following steps: positioning position information of a human face; calculating a first position of the face in an imaging area of the camera device, comparing the position with a target position, obtaining a first stepping rotation direction of the camera device, and executing first stepping; comparing the second position of the face in the imaging area of the camera device after the first stepping with the target position, collecting the direction of the second stepping rotation of the camera device, and executing the second stepping; and circularly comparing the position of the human face after stepping with the target position to obtain the direction of the second stepping rotation, and performing the second stepping until the deviation between the second position and the target position is within the preset deviation range. When the method is applied to a scene with a self-service face image collection function, the angle of the camera is gradually adjusted after the face information is recognized and detected, so that the face imaging achieves the optimal effect.

Description

technical field [0001] The invention relates to the technical field of biometric feature recognition, in particular to a face tracking method, system and electronic equipment of a camera device. Background technique [0002] The problem of face detection originally originated from face recognition. The research on face recognition can be traced back to the 1960s and 1970s. After decades of tortuous development, it has become increasingly mature. At present, there are many researches on face detection abroad, such as MIT, CMU, etc.; domestic Tsinghua University, Institute of Computing and Automation of Chinese Academy of Sciences, Nanjing University of Science and Technology, Beijing University of Technology, etc. have personnel engaged in research related to face detection. . Moreover, the MPEG7 standard organization has established a face recognition draft group, and the face detection algorithm is also a solicitation. With the deepening of face detection research, the n...

Problems solved by technology

[0007] At present, in the self-service face image collection process of the camera device, there is a technical problem that the position and angle of view of the collected image cannot achieve the optimal effect due to the limitation of the camera's own viewing angle on the camera device.
