Embodiment

[0037] see figure 1 , the intelligent skipping rope counting method of the present embodiment comprises the following steps:

[0038] In step S1, the video data of the rope skipping action is acquired through a video recording device, and audio data and image data are extracted from the video data.

[0039] Step S2, extract the sampling frequency of the audio from the audio data, and draw an audio waveform diagram with time as the abscissa, such as figure 2 As shown, the period T of the rope skipping action is determined according to the period of each sharp sound in the audio waveform diagram 1 , this embodiment takes the average value of all cycles.

[0040] Step S3, performing single-frame processing on the image data to obtain a set of sequentially arranged single-frame images.

[0041] Step S4, determining a reference area of ​​a single frame image, and intercepting the reference area to obtain a reference image. The reference area has to pass every time the rope is...

Abstract

The invention discloses an intelligent rope skipping counting method and belongs to the technical field of intelligent body-building equipment. The intelligent rope skipping counting method comprisesthe following steps; 1) obtaining video data of rope skipping actions and extracting audio data and image data from the video data; 2) extracting a sampling frequency of audio from the audio data, drawing an audio waveform graph with time as a horizontal ordinate, and determining a period T1 of one rope skipping action according to the audio waveform graph; 3) carrying out single frame processingon the image data to obtain one group of single frame images arranged in sequence; 4) determining a reference area of the single frame images and cutting out the reference area to obtain a reference image; 5) carrying out binarization processing and edge tracking on the reference image, separating out a target, and judging whether the target is rope skipping or not; 6) judging whether a time interval between adjacent reference images when the target is rope skipping is less than T1 or not, and if so, regarding as a repeat count and not increasing the count; and otherwise, increasing once count; and 7) outputting and displaying a counting result.

Description

technical field [0001] The invention relates to the technical field of intelligent fitness equipment, in particular to an intelligent rope skipping counting method. Background technique [0002] Rope skipping is one of the sports that people often engage in. Rope skippers need to count in the process of skipping rope, that is, they need to know the amount of exercise as an exercise indicator. However, in the use of existing rope skipping, people need to count or Counting by the referee, when counting by yourself, on the one hand distracts the rope skipper's attention, on the other hand it is easy to count wrong. When counting by a referee, it is also prone to counting errors. [0003] In the prior art, there is a method of installing an electronic counter in the handle for counting, such as a counting skipping rope disclosed by the publication number CN107715368A, which includes a rope body and handles respectively arranged at two ends of the rope body; the rope body adopts...
