The invention discloses a method for capturing face images. The method comprises the following steps of obtaining a target face image; performing front face detection on the obtained target face image to judge whether the obtained target face image is a front face image; if the obtained target face image is the front face image, judging whether a target face image saved in a face container is the front face image; and if the saved target face image is not the front face image, replacing the saved target face image with the obtained target face image. The method provided by the invention is capable of performing front face image detection according to the obtained target face image and then replacing the saved non-front target face image with the detected front target face image to ensure the acquisition of the front target face image; as a result, the problem that a face capturing system is incapable of automatically identifying the front face image and difficult to ensure that the captured face image is the front face image is solved.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a method and device for capturing human face images. Background technique [0002] In recent years, with the advancement of national strategic projects such as "Smart City" and "Safe City", the public security organs have improved their ability to maintain social order and serve people's livelihood, and fully adopt today's high-definition, networked, and intelligent monitoring new technology construction All kinds of video surveillance systems have become a trend. Face capture devices have begun to be widely used at the entrances and exits of urban villages, smart communities, commercial buildings, industrial and mining enterprises, etc., to capture the faces of people entering and leaving. [0003] The traditional face capture system only captures when the face touches the monitoring line or leaves the monitoring area. The number of captured face images is small, and often the c...
