Problems solved by technology

[0003] In terms of medical care, traditional posture correction methods require the company and guidance of professionals, which wastes a lot of manpower and material resources and also makes participants feel boring, often failing to achieve the expected rehabilitation effect
In addition, some research institutions have applied Sony EyeToy and Nintendo Wii to limb movement rehabilitation training, but the limitations of their two-dimensional image processing have restricted the development of this technology in the field of rehabilitation

Embodiment 1

[0068] A posture correction method based on depth information and bone information, such as figure 1 As shown, the specific steps include:

[0069] (1) Effective bone point screening based on user ID and bone space coordinate depth value: use the Kinect2.0 camera to obtain user bone data and depth data, and select all bone points of the target user; user ID refers to the unique Kinect2.0 sensing device The user tracking identifier is assigned to each user within the effective line of sight to distinguish which user the skeleton information belongs to; for example figure 2 shown, including the following steps:

[0070] A. Utilize the Kinect2.0 camera to obtain the bone data and depth data of all objects within the effective line of sight. The bone data refers to the coordinates of the bone points in the bone space coordinate system; the bone space coordinate system refers to: with the Kinect2.0 camera is the origin, the Z axis is in the same direction as the Kinect2.0 camera...

Abstract

The invention relates to a posture correction method based on depth information and skeleton information, and the method comprises the steps: (1), carrying out the effective skeleton point screening based on a user ID and a skeleton space coordinate depth value; (2), carrying out the smoothing of the skeleton information, and carrying out the coordinate standardization of skeleton points in a skeleton space coordinate system; (3), drawing skeleton vectors, and calculating a direction cosine value of each skeleton vector; (4), obtaining a training data set and a testing data set; (5), enabling the data sets to serve as the input of a Bayes regularization BP neural network, and carrying out the recognition of 25 skeleton points and 24 skeleton segments through the Bayes regularization BP neural network; (6), carrying out the analysis and processing of a result. The method irons out the defect that a color camera is liable to be affected by light, can accurately track a human body in a visual field, and also improves the naturalness of man-machine interaction.

Description

technical field [0001] The invention relates to a posture correction method based on depth information and bone information, and belongs to the technical field of intelligent perception and intelligent computing. Background technique [0002] In daily life, posture correction is used in many fields, for example, in medicine, it can be used for rehabilitation treatment of Parkinson's syndrome, muscle spasms and other movement disorders; in education, it can be used for teaching basketball, rhythmic gymnastics, dance and other projects; In terms of fitness and entertainment, it can be used for posture correction in yoga, Pilates and other projects to help bodybuilders achieve the desired fitness effect. According to reports, among Asians over the age of 40, one out of every three may suffer from Locomotive Syndrome. Reasonable exercise therapy is an essential rehabilitation method for this type of disease, and gymnastics , Yoga, Pilates and other projects, the quality of the ...
