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 perf

Example Embodiment

[0027] Example 1: (1) First, the method provided by the present invention plays a teaching video on the Internet terminal. The teaching video is shot in advance as required. The coach is shot on a green screen background. Various background synthesis and motion determination areas can be added in post-processing. This is done for the original green screen video, so that the background can be effectively separated from the coach. At the same time, the area containing the entire exercise process is selected, and the input video area is defined according to the 4:3 format; a wide-angle camera is installed on the Internet terminal to simulate the exercise of the students The process is filmed and played together with the coach’s video in a small window, so that students can see their actions in the small window as if they are seeing themselves in the mirror, and it is easy to compare their actions with the coach’s actions and observe themselves in real time. The difference between t...

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, ...
