Human body action comparison system based on human body posture obtaining system

Abstract

The invention discloses a human body action comparison system based on a human body posture obtaining system, and the system comprises a human body posture obtaining system used for obtaining the human body posture information of a user; a human body model conversion system used for converting the human body posture information into a human body model and establishing a motion process animation;an analysis and calculation system used for carrying out joint and muscle stress analysis and calculation on the human body posture information, calculating a mechanical model in the user movement process animation and the standard movement process animation, annotating the key data to the related positions of the mechanical model, and obtaining an annotated user human body model and an annotatedstandard human body model; and the comparison system is used for obtaining difference information of real-time actions and standard actions of the user, the system can meet 3D and 2D teaching effectsat the same time, and cost for students to obtain professional coach teaching can be greatly reduced.

Description

technical field [0001] The present invention relates to the field of human motion research, in particular to a human body motion comparison system based on a human body posture acquisition system. Background technique [0002] Currently, there are two solutions for the realization of the teaching of competitive sports, physical fitness, dance, human body posture, etc. on the Internet. 1. The 2D solution mainly plays the pre-recorded video and audio files. Students follow up the learning according to the video (audio) content played. 2. The 3D solution is an interaction based on VR+optical motion capture (or inertial motion capture). [0003] Disadvantages of the 2D program: 1. This program is an open-loop system, and the students cannot know and judge whether the movements they are doing are correct, whether the muscle groups and specific ways of exerting force are correct. 2. The information conveyed by the video (audio) content needs to be judged and understood by the s...

Problems solved by technology

[0006] The present invention provides a human body action comparison system based on the human body posture acquisition system, which is dedicated to low-cost solutions to 3D (2D) methods, which appear during the teaching of competitive sports, physical fitness, dance, and human body postures on the Internet. Inconvenient to use and poor teaching effect reflected in on-site teaching by coaches in reality
