Embodiment 1

[0049] A living body detection method provided by the embodiment of the present invention, such as figure 1 As shown, the method includes:

[0050] S11: Obtain a face image to be detected.

[0051] As a preferred implementation of this embodiment, face images used for liveness detection are collected. Specifically, the face image to be detected is obtained by collecting the image of the face area in the image, wherein the image may be a static image of a single frame or a dynamic image of multiple frames.

[0052] Wherein, the specific process of image acquisition can be as follows: firstly collect the real-time video stream of human face through the camera device, such as collecting the real-time video stream of human face through the front camera or rear camera installed on the mobile terminal, and sequentially analyze the real-time video stream of human face in the video stream The image frame is processed; after the video stream is obtained, the face detection algorithm ...

Embodiment 2

[0087] A living body detection method provided by the embodiment of the present invention, such as figure 2 As shown, the method includes:

[0088] S21: Obtain a face image to be detected.

[0089] In this step, face images for liveness detection are collected. Specifically, the face image to be detected is obtained by collecting the image of the face area in the image, wherein the image may be a static image of a single frame or a dynamic image of multiple frames.

[0090] For example, the specific process of image acquisition can be as follows: firstly collect the real-time video stream of human face through the camera device, such as collecting the real-time video stream of human face through the front camera or rear camera installed on the mobile terminal, and sequentially analyze the real-time video stream of human face in the video stream. The image frame is processed; after the video stream is obtained, the face detection algorithm is used to detect the face of the f...

Embodiment 3

[0116] An embodiment of the present invention provides a living body detection device. The living body detection device includes: a first living body classifier and at least one post living body classifier.

[0117] It should be noted that the first living body classifier is used to acquire the face image to be detected. The first living body classifier is also used to perform first-level living body detection on the face image to obtain a first living body detection result.

[0118] Further, the post-stage living body classifier is used to perform at least one stage of post-stage biopsy detection on the face image to obtain at least one post-stage detection result respectively when the first live body detection result is unpassable. The post-living classifier is also used to perform the next level of post-living detection when the current post-testing result is unpassable, until the last level of post-living detection to obtain the final detection result. The post-stage livi...

Abstract

The invention provides a living body detection method, device, electronic equipment and storage medium, and relates to the technical field of image detection. A living body detection result; when the first living body detection result is passed, the first living body detection result is used as the final detection result; when the first living body detection result is unable to pass, at least one level of rear living body detection is performed on the face image, Obtain at least one post-detection result respectively; solve the problem that the computational load or model volume of the living body classifier used in the living body detection process in the prior art is relatively large, which leads to the slowdown of the living body detection speed and reduces the detection efficiency of the living body detection technical problems.

Description

technical field [0001] The present invention relates to the technical field of image detection, in particular to a living body detection method, device, electronic equipment and storage medium. Background technique [0002] The current liveness detection means that the user takes corresponding actions according to the system instructions to prevent the user from using photos to fool the system to complete the verification in some important environments. After the user completes the corresponding actions according to the system prompts, the background will recognize the actions completed by the user and prompt the user whether the liveness test has passed. [0003] Liveness detection has its applications in social security, online account opening and other important occasions. Only after verifying that the identity of the elderly is true and alive can they receive pensions. When opening an account online, user verification is required to prove that the user did not use a ph...
