Problems solved by technology

[0004] Nowadays, intelligent methods based on vision can also be used to count rope skipping, but we are faced with the problem of how to identify rope skipping, etc. Since the rope is relatively thin and the speed of rope skipping is relatively fast, the number of rope skipping can be achieved by identifying the number of times the rope is swung There are also many problems in the counting of

Embodiment

[0049] see Figure 1 to Figure 4 , the rope skipping counting method based on image information of the present embodiment comprises the following steps:

[0050]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.

[0051] 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.

[0052] 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;

[0053] For the detection of the face shape and center position, it is only necessary to locate the face position in the image and obtain the minimum circumscribed rectangle of the face, that is, ...

Abstract

The invention discloses a rope skipping counting method based on video image target recognition, which belongs to the technical field of intelligent fitness sports, and includes: 1) acquiring original video data of rope skipping action, and extracting image data from the original video data; 2) processing the image data Perform single-frame processing to obtain a group of sequentially arranged single-frame images; 3) determine the face area of ​​the person skipping rope in each frame image; 4) take out the height coordinates of the center point of the face area; 5) obtain the height coordinates of the center point with For the time-varying curve, use the zero-crossing counting method to obtain the rope skipping times; 6) Output and display the counting results. After obtaining a relatively stable video image, the video information is processed, and then the obtained image data is analyzed to judge the number of rope skipping, and finally determine the number of rope skipping. This method judges the number of rope skipping by identifying the position of the face, which is not only accurate, but also the video can be reshaped, which has good application value.

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 video image target recognition. Background technique [0002] Rope skipping has been used as an important sport for entertainment or competition on many occasions. At the same time, it is also a compulsory subject for the physical examination of elementary and middle school students. However, counting is required in the process of skipping rope. When there are many people, counting each person will greatly delay the precious time of the referee, and sometimes when the rope skipping speed is fast or the referee is inattentive, counting errors are prone to occur. The existing skipping ropes that can count automatically often have problems such as not being accurate enough in counting, unable to reversely count, and not being used for a long time. [0003] For example, the Chinese patent literature with the publication...
