Living body detection method and device, electronic equipment and storage medium

Abstract

The invention discloses a living body detection method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a to-be-detected picture; inputting a to-be-detected picture into the target object recognition model, and outputting and obtaining a target area picture where a target object in the to-be-detected picture is located; clipping the target area picture based on a preset clipping rule to obtain at least one clipped picture; extracting LBP features of the cut pictures, and obtaining target feature maps in one-to-one correspondence with the cut pictures based on the LBP features; according to the target feature map and a preset target object living body detection model, obtaining a living body probability value of the target object in the to-be-detected picture; determining a living body state of the target object in the to-be-detected picture based on the living body probability value. According to the method, the to-be-detected object with certain incompatibility can be detected, the living body state of the to-be-detected object in the to-be-detected picture can be rapidly and accurately recognized, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of living body detection, in particular to a living body detection method, device, electronic equipment and storage medium. Background technique [0002] With the development of modern image processing technology and the improvement of image modification space, in the service of animals (such as dogs), especially in the insurance business, it is necessary to identify and detect the objects to ensure the authenticity of the objects; [0003] Liveness detection of animals (such as dogs) means that the computer first detects objects in the area of ​​​​animals (such as dogs), and then determines whether the detected animals (such as dogs) are real or fake, such as reproduced pictures , video, etc. At present, it is usually face detection, which cannot be directly used on animals (such as dogs). Moreover, animals (such as dogs) are autonomous, and there is a certain degree of incompatibility, and they cannot be...

AI Technical Summary

Problems solved by technology

At present, it is usually face detection, which cannot be directly used on animals (such as dogs)

Moreover, animals (such as dogs) are autonomous, and there is a certain degree of incompatibility, and they cannot be detected by instructions. An efficient animal body detection method directly based on pictures is needed
