Method for measuring throwing distance of track and field throwing project and long jump distance of long jump project based on image processing

Abstract

The invention discloses a novel method for measuring the throwing distance of track and field throwing projects and the long jump distance of long jump projects. According to the method, one or more cameras are erected beside a site, and the throwing distance and the long jump distance are measured through an image processing method. Hardware equipment used in the invention comprises one or more cameras and a computer or other equipment for running an image processing program, and can also comprise a large screen for displaying a measurement result and the like. The software aspect comprises an image processing program running on a computer or other equipment, and can also comprise a program for displaying a measurement result and the like. The method has the following characteristics: 1, the whole distance measurement process is automatically completed by the system, and manual participation is not needed; 2, instruments and sites do not need to be transformed; 3, the measurement error is within 1cm, which meets the requirements of the International Athletics Association; 4, the real-time performance of measurement is high, and only less than 1 second is needed from landing to result calculation; and 5, all hardware devices are universal devices, so that the cost is low.

Description

technical field [0001] The invention belongs to the field of sports track and field training and match refereeing, and in particular relates to a method for measuring the throwing distance of track and field throwing events and the long jump distance of long jump events. Background technique [0002] In the training and competition of track and field throwing events (including javelin, hammer put, shot put, discus) and long jump events (including long jump and triple jump), it is necessary to accurately measure the distance of throwing and the distance of long jump. At present, the measurement of this type of distance mainly relies on manual methods. The measurement work is cumbersome, the efficiency is not high, and the measurement data is often inaccurate. In the javelin and hammer throws, the landing area is a dangerous area, and the measurement personnel need to improve Be vigilant, incidents of javelin and hammer injuries also occur from time to time. [0003] In order...

Problems solved by technology

At present, the measurement of this type of distance mainly relies on manual methods. The measurement work is cumbersome, the efficiency is not high, and the measurement data is often inaccurate. In the javelin and hammer throws, the landing area is a dangerous area, and the measurement personnel need to improve Be vigilant, incidents of javelin and hammer injuries also occur from time to time

[0003] In order to solve the above problems, some new technologies have appeared in this field, such as "A Javelin Distance Measuring Device" with application number 2016100375035, "A Javelin for Automatic Range Measurement" with application number 2015204297055, and application number is 2016103370688's "Electronic Device for Automatic Measurement of Shot Put Distance", etc., the common feature of these technologies is to modify the equipment and (or) the field, and these modifications have the following problems: 1. Can they be recognized by the Athletics Federation? ;2. Will the modification of the equipment affect the weight and center of gravity of the equipment, thereby affecting training and competition;

All of the above limit the practicability of these technologies and limit their promotion and popularization
