Human facial identification method and system, as well as infrared backlight compensation method and system

摘要

A human facial identification method and system are disclosed, which belong to the mode identification technical field and intend to improve veracity of human facial identification implemented in outdoor environment. The human facial identification method includes: driving a group of infrared lamps by a high frequency pulse signal to generate infrared backlight, collecting identified human facial features in irradiation of the infrared backlight, comparing the collected identified human facial features with a human facial template to complete the human facial identification. A human facial compensation method and system are also disclosed, which are intend to improve luminance of infrared backlight. The technical solutions are mostly applied to the human image identification field.

1. A human facial identification method, characterized in that it comprises:
driving a group of infrared lamps with a high-frequency pulse signal to generate infrared backlight; collecting features of a human face to be identified under illumination of the infrared backlight by a human facial feature collecting device; and comparing the collected features of the human face to be identified with human facial templates to identify the human face, wherein the high-frequency pulse signal is synchronized with a field black-out signal in such a way that the group of infrared lamps are on only during a whole field black-out period of the human facial feature collecting device; and an exposure time point of the human facial feature collecting device is within the field black-out period.
