Abstract
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.
