Embodiment 1

[0060] like figure 1 As shown, it is a schematic flow chart of the human pulse measurement method of this embodiment, including:

[0061] Step S100: After the mobile terminal with the photographing device is placed at the position for measuring the human body pulse, acquire continuous images captured by the mobile terminal. Among them, the human body pulse measurement position is the most intense position that can be perceived by the human body pulse, such as figure 2 As shown, the point A where the pulse of the human body beats the strongest can be found by touching the wrist of the human body. image 3 It is a schematic diagram of placing a mobile terminal (such as a mobile phone) at the position for measuring the pulse of the human body. understandable to make image 3 The center position B of the mobile terminal shown is the same as figure 2 The shown human body pulse measurement position A coincides with each other, and the effect of the mobile terminal sensing the hu...

Embodiment 2

[0075] like Image 6 As shown, it is a schematic flow chart of the human pulse measurement method of this embodiment, including:

[0076] Step S200: After the mobile terminal with the photographing device is placed at the human body pulse measurement position, acquire continuous images captured by the mobile terminal.

[0077] Step S201: Detect the number of times N of changes in the displacement direction of the position of the feature region on the same axis of the image in the continuous images captured within a preset time.

[0078] Step S202: Determine the human pulse frequency with N.

[0079] Step S203: Filtering is performed during the number N of displacement direction changes of the position of the feature region in the continuous images taken within the detection preset time on the same axis of the image to remove the jitter interference signal.

[0080] The execution of step S200 to step S203 may refer to step S101 to step S103 in the first embodiment.

Abstract

The invention discloses a method and device for measuring a human body pulse and a mobile device. The method comprises the steps that after the mobile terminal provided with a camera is located at the human body pulse measuring position, continuous images shot by the mobile terminal are obtained; the times N of changes of displacement directions of the positions of characteristic areas of the continuous images shot in preset time in the same axial direction of the images are detected; the frequency of the human body pulse is determined according to N. According to the technical scheme, the method for measuring the human body pulse has the advantages of being low in achieving cost, convenient to achieve and good in compatibility.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a method, device and mobile terminal for measuring human pulse. Background technique [0002] With the development of electronic technology, mobile terminals (such as mobile phones) support more and more functions. Among them, there are many applications related to human health, such as measuring the human pulse or heart rate. [0003] At present, the main ways to measure human pulse through mobile terminals are: [0004] Measured with an infrared sensor. The principle is: with the beating of the human heart, the translucency of human tissue changes accordingly. When the blood is sent to the human tissue, the translucency of the tissue decreases; when the blood returns to the heart, the translucency of the tissue increases. This phenomenon is most obvious in parts such as fingertips and earlobes where human tissue is relatively thin. If the mobile terminal has an infrare...
