Abstract

The invention provides a multi-view camera exposure method and device, equipment and a medium. The multi-view camera exposure method comprises the following steps: acquiring at least two frames of images acquired by the same target object under the same or different illumination conditions by using a multi-view camera; and when it is detected that the face of the target object cannot be obtained in any image, re-determining a face area in the any image according to face positions obtained by other images, and re-exposing the face area to obtain a face image. According to the invention, throughmutual reference of human face positions, all cameras can be ensured to be normally exposed to obtain human face images; meanwhile, the exposure effect of the camera under strong light, backlight anddark environment is greatly improved; and when the method is applied to in-vivo detection, the identification rate of in-vivo detection is also greatly improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-eye camera exposure method, device, equipment and medium. Background technique [0002] With the continuous updating of security technology, face recognition technology is more and more widely used in life. Especially in government departments, face access control, gates, attendance and financial industries, it plays an irreplaceable role of intelligent security monitoring in security protection. [0003] However, when a binocular camera or a multi-camera captures the face in the image, the performance of the camera itself is affected by the dynamic range and exposure algorithm due to scene limitations, making it impossible to obtain a clear face image, and the output is not good, for example, strong Faces are too dark in backlit scenes, and faces are overexposed in strong forward light scenes. Therefore, there is an urgent need for a multi-camera exposu...
