Problems solved by technology

[0003] The traditional method of measuring heart rate is mostly obtained by measuring pulse oxygen saturation (SpO2) and using a more accurate electrocardiogram instrument. However, the above methods require the person to be tested to either clamp fingers, ears, or wear a chest strap during the test. Or wristbands even require electrode devices to be attached to the skin surface. These detection probes may cause discomfort to patients during monitoring (especially pinching fingers or ears for a long time during exercise) and increase the risk of spreading bacterial and viral infections. It brings inconvenience to the integration of smart devices, so it becomes an attractive research topic to find a sensor that does not rely on electrodes or other sensors that do not need to touch the skin and can measure heart rate in real time

Embodiment 1

[0063] A kind of non-contact heart rate detection method device based on camera (as attached Figure 7 shown), including an image acquisition module, an image processing module, a display module, an audio module and a treadmill control system;

[0064] The image processing module is connected with the treadmill speed control system, and the speed control of the treadmill is realized by outputting control commands to the control system (see attached Figure 8 shown).

[0065] The image acquisition device, display and audio module are all connected with the treadmill control system.

[0066] In addition to displaying time, speed, distance and heat information, the display also has heart rate information.

[0067] The audio module is not only for users to enjoy music, but also for voice warning under abnormal conditions.

[0068] The image acquisition device is used to collect video images, and transmit the image information of the athlete to the image processing module, and t...

Embodiment 2

[0079] Embodiment 2: the image acquisition device is a mobile phone utilizing a front camera (as attached Figure 9 Shown), measure the heart rate of the mobile phone holder. Wherein said image acquisition module and image processing module (as attached Figure 10 As shown), the program instructions are stored in the storage device of the mobile phone, and the calculation of the algorithm of the above-mentioned heart rate detection method is realized by the CPU of the mobile phone.

[0080] The present invention may employ the processor(s) of one or more embedded processors or other programmable data processing devices having computer usable program code embodied therein, and available storage media including, but not limited to, magnetic disk storage and optical storage, and the like.

Abstract

The invention discloses a camera shooting based non-contact heart rate detection method and device, and relates to the technical field of heart rate measurement. The method includes step A, step B, step C and step D. The device includes an image collecting module, an image processing module, a display module and a treadmill control system; and the image processing module is connected to the treadmill control system, and speed control of a treadmill can be realized by outputting a control instruction to the control system. In summary, compared with existing treadmills which can provide heart rate data and the way of using chest belts, a non-contact based heart rate measurement mode can be realized through the method and the device, the noninvasive, painless and extremely convenient heart rate measurement method can be realized by using a camera, and an important physiological index can be provided when people exercise on the treadmill so that a reference for health can be made.

Description

technical field [0001] The invention relates to the technical field of heart rate measurement, in particular to a heart rate measurement method and device for non-contact real-time monitoring of heart rate using camera. Background technique [0002] Heart rate refers to the number of times the heart beats per minute, which is an extremely important indicator of human health. As Chinese society enters a new era, the people's growing need for a better life has become the main contradiction in society, and healthy life has become a social priority. Therefore, various indicators related to human health have attracted increasing attention; at the same time, the development of smart technology has also promoted the entry of smart devices into ordinary households. As an activity that is not affected by the weather, using a treadmill for indoor running is convenient for users. Exercise your body for a healthy life. [0003] The traditional method of measuring heart rate is mostly o...
