Pull-up counting system based on image processing and counting method thereof

Abstract

The invention discloses a pull-up counting system based on image processing and a counting method thereof. The method is characterized by under conditions of a given horizontal bar height, a camera parameter and a shooting environment, according to a shot image sequence, using linear detection, face detection and skin color detection in a digital image processing theory to acquire positions of a horizontal bar, a face and hands; and for a detected correlation area, according to an image rotation invariant moment theory, calculating a zero moment and a first moment of a binary image, and determining accurate face and hand mass center positions and a face area; and then tracking and recording face and hand position changes of a whole image and image gray value changes of a specific area, and through programming analysis, calculating pull-up times of an athlete. Because a non-contact measurement technology is adopted, anti-environment interference capability is high. A position detection technology is mature and a counting error is low. A low computer performance requirement and short execution time are possessed. A rapid, reliable, accurate-counting and real-time requirement is reached. when athletes with different heights and different sexualities carry out test counting, a program does not need to be changed.

Description

Pull-up counting system and counting method based on image processing technical field The invention relates to the fields of image processing and machine vision, in particular to a pull-up counting system and counting method based on image processing. Background technique Pull-ups, an optional item for the middle school entrance examination and high school physical education examination, mainly test the development level of upper limb muscle strength. It is an examination item for male upper limb strength. It is a hanging strength exercise that overcomes its own gravity through the strength of the upper arm. It is the most basic way to exercise the back , is also one of the important reference standards and items for measuring male physique, and it is of great significance to quickly and accurately count the number of pull-ups. The current counting of pull-up items is mainly done manually, which is time-consuming, labor-intensive, and has high labor costs. The long-term o...

Problems solved by technology

The system has liberated manpower to a certain extent and improved the automation of pull-ups, but the image sensor of the system is the Kinect of Microsoft Corporation, which is expensive, and the depth image data set collected by Kinect is very large, resulting in High computer performance requirements, difficult to meet real-time requirements

On the whole, although the current pull-up counting device has improved in automation and counting accuracy, it is still not practical.
