Abstract

The embodiment of the invention discloses a living body detection method and device, a storage medium and electronic equipment. The method comprises the steps: determining a near-infrared image and avisible light image; identifying a to-be-detected object from the near-infrared image, and determining a first living body detection result of the to-be-detected object; identifying a to-be-detected object from the visible light image, and determining a second living body detection result of the to-be-detected object; obtaining the illumination intensity in the space where the to-be-detected object is located; determining the credible state of the second living body detection result according to the illumination intensity; and determining a final living body detection result of the to-be-detected object according to the first living body detection result, the second living body detection result and the credible state. According to the embodiment of the invention, the final living body detection result of the to-be-detected object can be prevented from being influenced by a poor imaging effect of the visible light image in a scene with weak or too strong illumination intensity, and thefinal living body detection result of the to-be-detected object can be accurately judged in various illumination environments.

Description

technical field [0001] The present disclosure relates to computer vision technology, in particular to a living body detection method and device, storage medium, and electronic equipment. Background technique [0002] Liveness detection is a method to determine the real physiological characteristics of a subject in some authentication scenarios. At present, the living body detection results of the near-infrared image and the visible light image are combined to determine the final living body detection result of the object to be detected. The detection object is a living body, otherwise, it is determined that the detection object is a non-living body. [0003] However, in a scene with weak light, the imaging effect of the visible light image is relatively poor. Therefore, the living body detection result of the visible light image may be inaccurate, which further leads to the final living body detection result described above may also be inaccurate.
