Problems solved by technology

These methods all use intelligent methods based on vision and hearing to count rope skipping, but they are faced with the problem of how to identify the rope skipping, and can only count the rope skipping by a single person. There are also many problems in identifying the number of swings of the rope to count the number of rope skipping
It is difficult to recognize the sound of rope skipping when there are many people skipping rope at the same time through sound recognition

Embodiment

[0077] see Figure 1 to Figure 4 , the rope skipping counting method based on multi-target tracking of the present embodiment comprises the following steps:

[0078] 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.

[0079] 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.

[0080] Step S3, perform face target recognition: obtain initial position and size information of multiple targets; specifically include:

[0081] Step S31, identifying the first human face object in the first frame image;

[0082] Step S32, find the human face target; if find the human face target, then perform step S33; if not find the human face target, then end and close the image;

[0083] Step S33, obtaining the position and size informati...

Abstract

The invention relates to a rope skipping counting method based on multi-target tracking, and belongs to the technical field of intelligent fitness exercises. The method comprises the steps that 1, original video data of rope skipping actions is acquired, and image data is extracted from the original video data; 2, single-frame processing is performed on the image data to obtain a set of sequentially-arranged single-frame images; 3, initial positions and size information of all face targets are acquired; 4, each face target in each frame of image is tracked, and meanwhile tracking results of all the face targets are displayed on the same frame of image; 5, rope skipping persons and non-rope skipping persons in the single-frame images are judged and recognized; 6, rope skipping counting is performed on all the rope skipping persons in the single-frame images; and 7, the results are output and displayed. The rope skipping persons and the non-rope skipping persons are recognized by recognizing and tracking the height position changes of faces, the rope skipping frequency of a plurality of rope skipping persons is judged, accuracy is achieved, manual counting is not needed, videos can be remolded, and the high application value is achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent fitness equipment, in particular to a method for counting skipping ropes based on multi-target tracking. 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. Existing skipping ropes that can count automatically often adopt traditional methods such as machinery, and there are problems such as the ubiquity of counting not being accurate enough, or not being able to count backwards, or not being able to use for a long tim...
