Problems solved by technology

On the one hand, it requires people to wear relevant sensors, which limits the range of measurement; on the other hand, it also brings inconvenience to people's normal life, and even causes varying degrees of damage to the human body in the long run
[0004]The commonly used non-contact vital sign data monitoring system, such as Chinese patent application 201110451364.8 reported a heart rate measurement method based on image capture, but in the implementation process cannot Intelligent tracking of test subjects requires manual selection of the subject's location; more importantly, for this traditional monitoring method, its algorithm is very complex
In addition, such an implementation cannot be well embedded into smart terminals, and it is difficult to be widely used in daily life

Abstract

The invention relates to a non-contact vital sign data monitoring system and a non-contact vital sign data monitoring method on basis of image processing. The non-contact vital sign data monitoring system comprises a video acquisition unit, an image processing unit and an output unit. Vital signs preferentially include heart rate and / or pulse wave, the video acquisition unit, the image processing unit and the output unit preferentially from a smart terminal with camera shooting function, particularly the function of monitoring the vital sign data can be realized by a smart cellphone or a tablet computer with the camera shooting function. The invention further provides a non-contact vital sign data monitoring method. Compared with a conventional vital sign data acquisition system, the non-contact vital sign data monitoring system has the advantages of independence of instrument contact, strong transportability, high accuracy and sensitivity and the like, and is ultrawide in application range.

Description

technical field [0001] The invention relates to monitoring vital sign data, in particular to a non-contact vital sign data monitoring system and monitoring method based on image processing. Background technique [0002] Vital signs are an important indicator to reflect the health status of the human body. play an important role in medical practice. With the advancement of modern medical methods and the rapid development of mobile medical care, single-point measurement of human health status through portable devices has become a hot spot. In this context, the monitoring of vital signs is undoubtedly an ideal research object. [0003] However, at present, the collection of vital signs is still mainly in the form of contact, with the help of sensors to sense changes in human vital signs, such as body temperature, heart rate, and respiratory rate. The drawbacks of such a method are obvious. On the one hand, it requires people to wear relevant sensors, which limits the range ...
