Embodiment

[0083] Analyze the force of the human body in the process of walking, and establish a tactile feature model about the human gait movement, which mainly includes the following steps:

[0084]Taking the support foot as the starting point of the model, through the dynamic analysis of the whole body, the ground support force model in the vertical direction is established. The force experienced in the vertical direction during the process. In the gait movement, the external force on the human body mainly comes from the reaction force of the ground, which is recorded as Let M be the total mass of the human body, then the gravity of the human body is like figure 2 . According to Newton's second law of mechanics, the dynamic equation of human force can be expressed as:

[0085] N y -Mg=Ma y

[0086] where Ma y It can be decomposed into the sum of the products of the mass of each part of the body and the acceleration in the vertical direction of the position of the center of...

Abstract

The present invention is a modeling method and application of a systemic gait motion model with fusion of vision. This method includes the following steps: simplifying the whole body's bone structure, and when building a modeling environment, the human body is divided into 11 rigid bodies, including left and right, including left and right, including left and rightFoot, left and right calves, left thighs, left and right arms, left and right arms, heads, and chest and abdomen; establish a touch -sensitive feature model about human gait movement, the human body stress is decomposed into the quality of the body and the vertical direction of its quality position.The sum of the volume of acceleration, that is, the touch -sensitive feature model; the acquisition of acceleration A needs to obtain the joint angle of each part through the visual image;, Get vision of the whole body gait motion model.This method establishes a more accurate visual anemia system for the changes in the body's gait movement.

Description

technical field [0001] The invention belongs to the field of pattern recognition, and in particular relates to a modeling method and application of a full-body gait motion model based on visual-touch fusion for gait recognition. Background technique [0002] With the development of computer vision and information security, more and more biometric technologies have been developed and utilized. Biometrics is a technology for identifying people based on unique physiological or behavioral characteristics, because it is not as easy to steal or transfer as documents such as ID cards, and thus becomes reliable. [0003] As one of the biometric technologies, gait recognition aims to identify people by their walking patterns. Compared with other identification methods, it has become a research hotspot because of its unique long-distance nature. Although the amount of identification data is large and it is difficult to extract features, this identification technology has several very...
