Embodiment Construction

[0032] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0033] like figure 1 As shown, a method for extracting the thinned centerline of the human body in the depth image proposed by the present invention first obtains the human body contour map, performs image smoothing processing on the human body contour map, and then adopts the depth image hierarchical segmentation processing method to obtain self-occlusion Finally, the image of the body region and the image of the self-occlusion region are thinned by the image thinning algorithm to obtain the thinning center line of the human body.

[0034] The specific implementation steps of the inventive method are as follows:

[0035] In step 1, smoothing and filtering are performed on the contour map of the human body.

Abstract

The invention discloses a method for extracting the thinned centerline of a human body in a depth image. Firstly, an outline image of a human body is obtained, and an image smoothing process is performed on the outline image of the human body, and then an image of a self-occluded part is obtained by adopting a hierarchical segmentation processing method of the depth image. Finally, the image of the body area and the image of the self-occlusion area are respectively thinned by the image thinning algorithm to obtain the thinning center line of the human body. The method of extracting the thinning centerline of the human body in the depth image designed by the present invention cleverly integrates the idea of ​​thinning line acquisition into the extraction of occlusion areas, solves the problem of self-occlusion, and obtains the thinning line containing depth information at the same time, which has the advantages of Real-time, high-efficiency and other advantages.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for extracting a thinned centerline of a human body in a depth image. Background technique [0002] With the rapid development of computer technology, "somatosensory" operation technology has increasingly entered people's lives as a new way of human-computer interaction. Robust human skeleton recognition is widely used in human-computer interaction, games, security, remote monitoring, and even medical treatment. There are a wide range of applications, and the emergence of depth cameras has made human skeletal model recognition cheaper and easier to implement. [0003] The skeleton maintains the original graph topology and is a powerful abstraction method to describe the basic topology of objects in two-dimensional or three-dimensional space. Human skeleton extraction using depth images can well overcome the interference of factors such as illumination changes, ...
