Problems solved by technology

Among them, the heart rate is an important indicator of human health. At present, people usually use the method of pressing the pulse to calculate the number of pulse beats in one minute. The psychological tension caused by it will cause errors in the heart rate detection.

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0023] figure 1 It is a flow chart of heart rate detection in a specific embodiment of the present invention. Such as figure 1 As shown, the heart rate detection process includes the following steps:

[0024] Step 101. Place the finger belly in front of the camera of the mobile terminal. The mobile terminal takes pictures of the finger belly through the camera at a frequency of 600 shots per minute. The shooting time is 30 seconds to 1 minute. Since the normal heart rate usually does not exceed 100 beats / minute, The frequency of taking photos of the finger pads by the camera is much higher than that of the heart rate.

[0025] Step 102, the mobile terminal stores all the photographs of finger pads taken in the internal memory of the mobile terminal.

[0026] Step 103: Calculate and record the av...

Abstract

The invention discloses a method for testing the heart rate of a user. The method includes enabling a camera of a mobile terminal to photograph finger pads of the user at a frequency lower that each heartbeat duration, and storing all finger pad photos; computing an average value of red pixel values in a RGB (red, green and blue) color model of all pixels in each finger pad photo and recording the average values; computing differences among the average values of the red pixel values in the RGB color models of all the pixels of each two adjacent finger pad photos to obtain a difference array; normalizing the difference arrays to obtain a second array; presetting a threshold value and judging to determine that the heart of the user beats once when a value in the second array is higher than the threshold value; and computing the heartbeat frequency within a minute to obtain the heart rate of the user. According to the technical scheme, the method has the advantage that the heart rate testing accuracy and the use interest of the user are improved.

Description

technical field [0001] The invention relates to the technical field of physical examination, in particular to a heart rate detection method. Background technique [0002] With the improvement of living standards, people pay more and more attention to their health. Among them, the heart rate is an important indicator of human health. At present, people usually use the method of pressing the pulse to calculate the number of pulse beats in one minute. The resulting psychological tension, etc., resulting in errors in heart rate detection. Contents of the invention [0003] The purpose of the present invention is to provide a method for heart rate detection, which can improve the accuracy of heart rate detection. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A method for heart rate detection, comprising the following steps: [0006] A. The mobile terminal takes photos of the pads of the fingers with a frequency of less...
