Abstract

A method of using an image of a subject to determine pose-related information of the subject, the method comprising: determining a first position of a first pair of joints according to a first image of a first body of a first body segment associated with the first pair of joints limb length; according to the second image to determine the second position of the second pair of joints and the second body limb length of the second body limb related to the second pair of joints; according to reduce the length of the first body limb and the second body Algorithm of difference in length of limbs to determine whether the first pair of joints and the second pair of joints correspond to the same pair of joints; if the first pair of joints and the second pair of joints correspond to the same pair of joints, then the body is determined according to the second position posture information; and related instructions that provide posture information.

Description

technical field [0001] The present invention relates to motion analysis, in particular to a system and method for determining and analyzing motion of a subject based on images. Background technique [0002] Motion analysis is an important discipline of biomechanics that is relevant to various applications such as balance assessment, measurement of force sensing, exercise science training, analysis of physical therapy, and operation of fitness equipment. Motion analysis is generally performed based on images. When a subject (such as a human) performs a specific action, the system captures a series of images for the subject. Based on the series of images, the system determines the position of each body segment of the subject at a specific time. According to the position information, the system can determine the action and / or posture of the subject at that time. [0003] Current technology provides many methods to perform image-based motion analysis. One method of motion ana...
