Method and system for counting vertical reciprocating movements based on mobile terminal

Abstract

The invention discloses a method and a system for counting vertical reciprocating movements based on a mobile terminal. The method comprises steps: S1, a video is acquired and stored at a preset visual point; S2, the video image acquired at the current time is detected whether to have a first image associated with a vertical reciprocating movement object, if yes, the position information of the first image is acquired, and a third step is executed, and if not, the second step is returned and executed; S3, according to the position information of the first image, a rectangular frame template is adopted to calibrate a first image in each frame of video image; S4, according to a calibration time sequence, the position information of the rectangular frame template in each frame of video image is extracted, and the position information is sequentially stored in a first queue in a first queue group according to the calibration time sequence; and S5, the first queue in the first queue group is processed and analyzed to acquire whether the first image completes a preset action, if the first image completes the preset action, the times for completing the preset action are accumulated, and the third step is returned and executed.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a non-contact up and down reciprocating movement counting method and system based on a mobile terminal. Background technique [0002] With the popularity of smart mobile terminals, applications based on smart mobile terminal platforms emerge in an endless stream, and various mobile terminal applications have penetrated into every aspect of people's lives. In the mobile terminal application market, there are many intelligent software used to record the number of times users exercise (such as squats, push-ups, etc.), in order to remind and encourage users to exercise more frequently, which is beneficial to the user's body. healthy. [0003] At present, software for counting up and down reciprocating motions on some existing mobile terminal platforms mainly adopts touch screen technology or proximity sensor technology. Although the touch screen technology has the advantages of simp...

AI Technical Summary

Problems solved by technology

Although the touch screen technology has the advantages of simplicity, accuracy and reliability, it has strict requirements on the user's squatting action standards. For example, when doing squats, the user needs to touch a specific area of ​​the mobile terminal screen, which is not convenient for users to use.

The working principle of the proximity sensor technology is to emit a short light pulse, and calculate the distance according to the time from when the light pulse is emitted to when it is emitted by the object. Since the proximity sensor has a very small range of action in actual operation, when the user's up and down When the squatting speed is too fast or there are obstacles nearby, the proximity sensor is prone to failure and the counting accuracy is low
