Falling behavior detection method, device and equipment and readable medium

Abstract

The invention is suitable for the technical field of action detection, and provides a fall behavior detection method, device and equipment and a readable medium, and the fall behavior detection method comprises the steps: obtaining a to-be-detected video of a target body, the to-be-detected video comprises multiple frames of images; posture data of target parts of each frame of image are obtained, the target parts comprise at least two parts of the neck, the waist and the feet, and the posture data of the target parts are used for representing posture changes of the target body; and determining whether the target body falls down or not according to the attitude data of the target part. According to the method, the situation that a large misjudgment probability exists in judging whether falling occurs or not is avoided, falling behaviors can be better detected, the accuracy of falling detection is improved, and the misjudgment probability of whether falling occurs or not is reduced.

Description

technical field [0001] The present application belongs to the technical field of motion detection, and in particular, relates to a fall behavior detection method, device, device, and readable medium. Background technique [0002] In daily life and work, users may fall, especially the elderly or children. Falls in the elderly or children pose a greater risk to life safety. Therefore, it is particularly important to be able to detect and avoid more injuries caused by falling behaviors in time. [0003] At present, in the related art, computational vision analysis technology is mainly used to analyze the behavior of users in surveillance videos, specifically, the neck is used as a stable reference point, and then the perceived height of the person is calculated according to the bounding box that defines the whole person, and finally Through frame-by-frame comparison, it is determined whether the user falls by determining whether the vertical distance of the key point where th...

AI Technical Summary

Problems solved by technology

[0007] The application provides a fall behavior detection method, device, equipment and readable medium, which can avoid the problem of high probability of misjudgment caused by the method of determining whether to fall by the vertical distance of the key point where the neck is located, and ensure that the The judgment of falling is more accurate, reducing the probability of misjudgment of falling
