Embodiment

[0064] see Figure 1 to Figure 6 , the skipping rope counting method based on intelligent target recognition of the present embodiment comprises the following steps:

[0065] Step S1, obtain the original video data of the rope skipping action through the video recording device, input the original video data, and start timing.

[0066] Step S2, extracting image data from the original video data, performing single-frame processing on the image data to obtain a set of sequentially arranged single-frame images, and extracting the counting time.

[0067] Step S3, determining the face area of ​​the rope skipping person in each frame of image. First, skin color recognition is performed on each frame of image, and the interference data is filtered out to obtain a binary image, such as figure 2 shown; then exclude the non-face skin color area; finally frame the face area in the original RGB image for backup, such as image 3 shown.

[0068] Step S4, extracting the height coordinat...

Abstract

The invention discloses a rope skipping counting method based on intelligent target identification, and belongs to the technical field of intelligent fitness exercises. The rope skipping counting method comprises the steps that (1) original video data of rope skipping actions are acquired, and image data and audio data are extracted from the original video data; (2) single frame processing is carried out on the image data to obtain a group of sequentially arranged single frame images; (3) face regions of rope skipping people in each frame image are determined, and the height coordinates of thecenter points of the face regions are taken out; (4) a curve of the height coordinates of the center points changing with time is acquired, and the number of times of skipping of the rope skipping people is acquired by adopting an over-zero counting method; (5) the sampling frequency of audio is extracted, an audio waveform chart with time as an abscissa is drawn, and the number of times of ropeskipping is calculated by adopting a cross-correlation coefficient method; (6) video information and audio information are merged to judge whether the number of times of rope skipping is effective ornot, if the number of times of rope skipping is effective, counting is increased by 1, and if not, counting is not performed; and (7) a counting result is output and displayed.

Description

technical field [0001] The invention relates to the technical field of intelligent fitness equipment, in particular to a rope skipping counting method based on intelligent target recognition. Background technique [0002] Rope skipping is a whole-body aerobic exercise suitable for all ages and an excellent fitness exercise. In addition to the general benefits of exercise, it has many unique advantages. Rope skipping consumes about 400 calories per half an hour. It can effectively train the individual's response and endurance, and help maintain the body's fitness and coordination. It has a considerable impact on various organs such as the cardiopulmonary system, coordination, posture, and weight loss. s help. [0003] With the continuous development of technology, there are more and more types of motion algorithms on bracelets or watches. Motion algorithm, originated in the early 21st century, is to obtain real-time data on the bracelet or watch through the sensor, then pr...
