Problems solved by technology

Therefore, the subjective setting value cannot accurately judge whether the environment is healthy
Secondly, existing heart rate detection methods require physical contact with people or wearing devices
Through these problems, it can be seen that the existing technology lacks a more convenient and accurate method for judging the health of the indoor living environment

Embodiment Construction

[0084] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

[0085] In order to more conveniently and accurately judge the health of indoor living environment, a method and system for adjusting the health of indoor environment based on machine vision are proposed. Using high-definition cameras to collect facial data of people living in a healthy environment for a period of time, using the remote photoplethysmography heart rate monitoring method based on the joint blind source separation algorithm to analyze the heart rate data from the facial data...

Abstract

The invention discloses a method and system for adjusting the health of an indoor environment based on machine vision, which includes the following steps: (1) collecting facial data of a person, and applying independent vector analysis to analyze a periodic signal from the facial data, thereby detecting heart rate; (2) Preprocess the collected heart rate data in a healthy environment to construct an environmental health language word model; (3) compare the collected heart rate data in the actual environment with the data in the constructed environmental health model to judge the environment Is it healthy. The invention can improve the accuracy of the heart rate monitoring value, quantify people's "feeling" through the heart rate, eliminate the interference of subjective consciousness, make the heart rate relatively stable, and make the judgment result more accurate.

Description

technical field [0001] The invention relates to a method for judging the health degree of an indoor environment, in particular to an adjustment method for judging the health of an indoor environment based on machine vision. The method relates to the field of smart home technology. Background technique [0002] In recent years, people pay more and more attention to the comfort and health of the living environment. According to survey statistics, people spend more than 80% of their time indoors every day, and indoor temperature has an important impact on people's health. Therefore, the appropriate indoor ambient temperature is an important factor in judging the health of the indoor environment. [0003] At present, when the indoor ambient temperature is detected, the method of sensor detection is mostly adopted, and then the collected value is compared with the subjectively set value to judge whether the environment is healthy. Due to the difference in physique and age of e...
