Embodiment

[0040] See Figure 1 to Figure 3 The method for counting skipping ropes based on image information in this embodiment includes the following steps:

[0041] Step S1: Obtain the original video data of the rope skipping action through the video recording device, and input the original video data to start timing.

[0042] Step S2: Extract image data from the original video data, perform single-frame processing on the image data to obtain a set of sequential single-frame images, and extract the counting time.

[0043] Step S3: Analyze the single-frame image to determine the common reference area of ​​all single-frame images, the reference area must pass through each time the rope skips, and the reference area is intercepted to obtain the reference image.

[0044] The reference area has to go through each time you jump rope (when the camera angle is different, the reference area may be different when different people jump rope). After the relative distance of the shooting and the relative ...

Abstract

The invention discloses a skipping rope counting method based on image information and belongs to the technical field of smart fitness sports. The method comprises the steps of 1, extracting image data from original video data and performing single frame processing on the image data to obtain a group of sequentially arranged single frame image; 2, determining a common reference area of all the single frame images and intercepting the reference area to obtain a group of reference images, wherein a skipping rope passes through the reference area each time; 3, performing binarization processing on each reference image and filtering out interference data; 4, performing edge tracking on each processed reference image to separate out a target; 5, extracting judgment data of the target and judging whether or not the target is the skipping rope according to the judgment data; 6, judging whether or not the time interval between every two adjacent reference images is shorter than the time of 10adjacent frames when the target is the skipping rope, determining the time interval as a repeat count without increasing a count if yes, and otherwise, increasing a count; 7, outputting and displayinga counting result.

Description

Technical field [0001] The invention relates to the technical field of intelligent fitness exercise equipment, in particular to a method for counting skipping ropes based on image information. Background technique [0002] Rope skipping is a sport in which various jumping actions are performed on the ropes of the swing. It is also a full-body aerobic fitness exercise and an excellent fitness exercise for all ages. In addition to the general benefits of exercise, it also has many unique advantages. Rope skipping consumes about 400 calories every half an hour, which can effectively train the individual's reaction and endurance, help maintain personal fitness and coordination, and have considerable influence on various organs such as the cardiopulmonary system, coordination, posture, weight loss, etc. s help. [0003] Now, skipping rope has been used as an important sport for entertainment or competition in many occasions. It is also a compulsory subject for the physical examinatio...
