Abstract

The present invention provides a heartbeat signal-based remote face recognition method, a heartbeat signal-based remote face recognition apparatus and a system. The method includes the following steps that: an image in a monitoring area is acquired, a pedestrian image is extracted from the acquired image, and a pedestrian space position is determined from the acquired image; an optical vibration imaging technology is utilized to obtain the space position of pedestrian heartbeat signals according to the pedestrian space position; the face space position of a pedestrian is positioned according to the natural position relation of heartbeat signals and a face; and an acquired area is adjusted to a face area according to the face space position, and a clear face image can be acquired. According to the heartbeat signal-based remote face recognition method of the invention, the space position of the heartbeat signals is utilized, so that the space position of the face can be calculated fast, the face area can be positioned fast, and the high-resolution face image can be obtained, and the recognition rate and practicability of a remote face recognition system can be improved.

Description

technical field [0001] The invention belongs to the field of biological feature recognition, and in particular relates to a remote face recognition method, device and system combined with a heartbeat signal. Background technique [0002] Face recognition refers to a technology that uses the stable features of the human face for identity authentication. As a typical biological feature, the human face is unique from other people and stable for a certain period of time. Compared with traditional identity authentication methods (ID card / passport / key / password, etc.), biometric features will not be lost, not easy to forge and counterfeit, and available at any time, which is an ideal identity authentication carrier. [0003] At the same time, face recognition is a non-invasive, convenient and friendly biometric identification method. According to the distance from the camera to the user, it can be divided into short-range face recognition and long-range face recognition technolog...
