Embodiment Construction

[0077] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0078] The invention provides a method for classifying human body postures. The human body area in the image is determined through human body detection, and then the outer contour of the human body is extracted from the human body area. At the same time, the position of the head is determined through head detection and tracking, and then according to the head position, Information such as the shape of the human body is used to classify the posture of the human body.

[0079] Such as...

Abstract

The invention discloses a classification method and a device of human body posture. The classification method of human body posture comprises the steps of: determining a human body region in an existing frame image; extracting the human body shape so as to obtain the external outline in the human body, then obtaining the information of the position of human head by human head detection; and then determining that the human body posture is in vertical standing-up status when the head part is right in the middle of the external outline of the human body; and further calculating the aspect ratio of the external outline of the human body when the head part is located at one side of the external outline of the human body, and then determining the types of human body posture according to the aspect ratio of the external outline of the human body, thereby achieving automatic identification and classification to the human body posture, without human intervention, thus making up the detects thatthe prior art does not provide a method for classifying the human body posture.

Description

technical field [0001] The invention relates to the technical field of image content analysis, in particular to a method and device for classifying human postures. Background technique [0002] There are various postures of the human body, such as standing, bending over, sitting, lying down, half lying down, etc. Human body posture analysis in images is one of the main contents of image content analysis. The main purpose is to estimate the position of various parts of the human body in the image and determine the posture of the head and limbs. After the posture of the human body is determined, information such as the current movement of the person can be further judged, and then applied to various application scenarios such as behavior analysis, video surveillance, human-computer interaction, and virtual reality. For example: in the hourly worker monitoring system, it is possible to determine whether the current hourly worker is lazy through the body posture; or, it is poss...
