Example Embodiment

[0063] The following will be combined with the Figure 1 to Figure 4 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0064] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a co-existence of an intervening component. When a component is considered to be "set on" anothe...

Abstract

The invention relates to the technical field of pull-up counting, in particular to a pull-up counting method based on image difference, which comprises the following steps: an athlete image acquisition step: acquiring a human body image of an athlete by adopting a camera, and preprocessing the acquired human body image to obtain a grey-scale map; and a background image extraction and real-time updating step: taking the smooth image of the grey-scale image in the athlete image acquisition step as a reference background image, comparing the contour of the current frame with the background contour, calculating the difference between the current frame and the reference background image, obtaining a difference image, and performing real-time updating. According to the method, the inter-frame difference image processing technology is adopted, the head area of the human body and the real-time position of the horizontal bar during pull-up are detected, positioning is simple, the problem that the calculation speed is low due to the fact that the calculation amount of pull-up is large is solved, and the effect that the number of pull-up completed by an athlete is calculated in real time is achieved.

Description

technical field [0001] The invention relates to the technical field of pull-up counting, in particular to a method for counting pull-ups based on image difference. Background technique [0002] Pull-ups, sometimes referred to as pull-ups, refer to hanging exercises that rely on one's own strength to overcome one's own body weight and do work upwards. It mainly tests the development level of upper limb muscle strength, as well as arm strength and waist and abdominal strength. In the process of completing a complete pull-up, many back skeletal muscles and upper limb skeletal muscles are required to participate in the work. It is a multi-joint compound exercise. It is a better way to exercise the upper limbs, and it is the most effective way to develop the muscle strength and endurance of the back skeletal muscles. In the test, the athletes' physical fitness is compared by calculating the number of pull-ups completed by the athletes. [0003] The Chinese invention with the pa...
