A teaching video and camera video motion comparison grading method

Abstract

The invention provides a teaching video and camera video motion comparison grading method comprising the steps of playing teaching video and acquiring camera video in real time by using a camera; acquiring a motion judging area; performing binarization processing on the motion judging area and expressing the front-and-back motion intensity of each element point by using normalization values; setting a threshold value and converting motion intensity images of the teaching video and the camera video into corresponding motion standardization matrixes; performing XOR operation on the motion standardization matrixes of the teaching video and the camera video to obtain motion difference matrixes and performing accumulation calculation on the motion difference matrixes to obtain motion similarity values in the teaching video and the camera video; performing normalization processing on the motion similarity values obtained through accumulation calculation of the difference matrixes to reflect motion difference. The method can perform mutual matching and comparison of motion of two pieces of video and identify the similarity of the two pieces of video and has the advantages of simple operation, low apparatus requirement and high universality.

Description

technical field [0001] The invention relates to the field of motion video processing, in particular to a method for comparing and scoring teaching video and camera video motion. Background technique [0002] With the improvement of people's living standards, more and more people begin to pay attention to their health, and fitness exercises have gradually become fashionable. However, China has a large population, and the per capita fitness equipment and venues cannot meet the growing demand. In addition, various disastrous weathers occur frequently, seriously affecting the public to carry out outdoor sports. So how to carry out indoor, especially family sports is a problem worth studying. [0003] At present, home sports equipment is mainly treadmills, but according to years of research, treadmills have many problems, resulting in poor frequency of use and durability. The existing problems include: 1) The treadmill mainly exercises the legs and performs aerobic exercises, ...

Problems solved by technology

[0003] At present, home sports equipment is mainly treadmills, but according to years of research, treadmills have many problems, resulting in poor frequency of use and durability

The existing problems include: 1) The treadmill mainly exercises the legs and performs aerobic exercises, while fitness exercises require full-body and all-round exercises, such as speed exercises, strength exercises, flexibility exercises, balance exercises, and special exercises that are included in scientific fitness requirements. Exercise, etc. These exercises cannot be performed on a traditional treadmill; 2) The exercise method provided by the treadmill is single, and the long-term mechanical running action will cause boring and fatigue, and it is difficult to persist in exercising for a long time

Due to the lack of interactive means, it is impossible to form a closed loop of teaching, and finally lacks a personalized evaluation system

Due to the above reasons, although video teaching has existed for a long time, the effect of actually guiding exercise, supervising exercise, and evaluating exercise is not very satisfactory.
