Abstract

The invention discloses a remote heart rate monitoring method and system based on a video image, and the monitoring method comprises the steps: obtaining a face image of a monitored object, and carrying out the preprocessing of the face image, and obtaining an analysis image; extracting a set area from the analysis image, and performing mean value calculation on image information of the set area to obtain a heart rate calculation queue matrix; obtaining heart rate data of the set area according to the heart rate calculation queue matrix; different set areas are selected for calculation, and heart rate data monitored this time are obtained through calculation according to the weight value of each set area; and in combination with the heart rate data monitored this time and the historical heart rate data of the monitored object, predicting the future health condition. According to the scheme, the heart rate of the detected object is monitored based on the image, the database is established, the weak heart rate signal is extracted from the complex background signal, the influence of the noise signal is effectively removed, the prediction result is reliable, and a reference basis is provided for disease prevention.

Description

technical field [0001] The invention relates to the technical field of heart rate monitoring, in particular to a video image-based remote heart rate monitoring method and system. Background technique [0002] With the rapid development of social economy and the change of national lifestyle, especially the aging of population and the acceleration of urbanization, the unhealthy lifestyle of residents has become increasingly prominent, and the impact of cardiovascular risk factors on residents' health has become more and more significant. Cardiovascular disease rate continued to increase. The "China Cardiovascular Health and Disease Report 2020" pointed out that the death of cardiovascular disease in China is the first cause of death among urban and rural residents, and the economic burden of cardiovascular disease on residents and society is increasing day by day. Because the monitoring of physiological parameters, especially the monitoring of changes in key physiological par...
