This application is applicable to the technical field of face recognition, and provides a face image acquisition method, a photographing device and a storage medium, wherein the face image acquisition method includes: in the photographing mode, acquiring the first image currently displayed on the photographing interface Brightness information; determine the target scene type of the shooting scene where the face is currently located according to the brightness information; if the target scene type is a backlight scene, then determine that the target shooting mode of the shooting device is a backlight shooting mode, and determine the infrared light set on the shooting device The target working state of the light is on; adjust the shooting mode to the backlight shooting mode and adjust the current working state of the infrared light to the on state before shooting to obtain the target face image. The face image acquisition method improves the brightness of the face by turning on the infrared light in the backlight shooting mode, thereby increasing the brightness of the face part in the target face image without losing the background information of the image and improving the brightness of the image. overall quality.
Description
technical field [0001] The present application belongs to the technical field of face recognition, and in particular relates to a face image acquisition method, a photographing device and a computer-readable storage medium. Background technique [0002] Face recognition technology is a biometric technology for identification based on human facial feature information. It has been widely used in various access control or monitoring systems. It is usually necessary to collect face images during face recognition, and when the face is in a backlit scene, the face in the collected face image is usually dark or even completely black, which will increase the difficulty of subsequent face recognition Spend. The traditional solution is to forcibly brighten the face through the backlight compensation exposure function. However, the backlight compensation will seriously overexpose the background in the face image, resulting in the loss of the background information of the image and red...
