Counting method and apparatus for sit-ups and mobile terminal

Abstract

The invention discloses a counting method and an apparatus for sit-ups and a mobile terminal. The method comprises the following steps: S100) obtaining the video images of a to-be-detected user during his making of the sit-ups; S200) detecting whether the video images contain the side face and the upper body of the user or not; and if the video images contain them, then, proceeding to the next step; and otherwise, returning to the step S100; S300) obtaining the contours of the side face and the upper body of the users in the video images and defining one monitoring line in the contours wherein the monitoring line consists of a plurality of monitoring points; S400) monitoring the traveling trajectory of the monitoring line; determining whether the to-be-detected user completes one sit-up or not; and S500) when one sit-up is detected to be completed, then adding one to the counter. According to the invention, a non-contact manner is adopted to count the sit-ups, and through the tracking of the side face by a camera, the requirement for body contact with a screen can be effectively avoided, therefore, eliminating the condition that the cell phone capable of counting sit-ups must be a screen-touch one.

Description

technical field [0001] The invention relates to the application field of intelligent terminals, in particular to a method and device for counting sit-ups and an intelligent terminal. Background technique [0002] With the popularity of smart phones, mobile phone applications based on smart phone platforms emerge in an endless stream, and various mobile phone applications have penetrated into every aspect of people's lives. As we all know, sit-ups can effectively exercise abdominal muscles and chest muscles, basically not limited by time and place. As a result, many convenient smart software have appeared in the mobile phone application market, which can record the number of sit-ups that people usually do when exercising, and remind and encourage them to exercise more frequently. [0003] At present, the software for counting sit-ups on some existing mobile phone platforms is mainly based on the following two technologies: touch screen technology and proximity sensor technol...

Problems solved by technology

[0004] For the use of touch screen technology, although such an implementation will be relatively simple, accurate and reliable, it has a very high requirement for the quality of the movement of the person doing sit-ups. When doing sit-ups, it is necessary to touch the The counter will only count on a specific place on the mobile phone screen. However, beginners generally cannot insist on doing multiple standard sit-ups in a row, and the effect of using it is not obvious

[0005] For the use of proximity sensor technology, since the working principle of the proximity sensor is to calculate the distance by emitting a short light pulse and measuring the time from when the light pulse is emitted to when it is emitted by the object, the actual range of the proximity sensor is very limited. Small, when the speed of sit-ups is too fast or there are obstacles nearby, the proximity sensor is prone to failure, so that it cannot count accurately, and the working effect is not satisfactory
