Abstract

The embodiment of the invention discloses a non-contact heart rate measurement method and a device based on Euler image magnification, used for solving the technical problems existing in the existingnon-contact heart rate measurement method that the heart rate is great in same-frequency noise interference and is greatly influenced by an environment temperature, isolation signal authenticity lacksjudgment and the like. The non-contact heart rate measurement method and device based on Euler image magnification in the embodiment of the invention comprises the following steps: S1, magnifying tiny change of radial artery jump in a video through an Euler image magnification technology; S2, performing luminance variance statistics on a video frame pixel point luminance channel after magnifyingthe tiny change of radial artery jump in a time domain, performing skin segmentation on the video frame subjected to magnification of the tiny change of radial artery jump, and extracting a radial artery jump area; and S3, performing time-frequency analysis on the radial artery jump area so as to calculate the heart rate.

Description

technical field [0001] The invention relates to the field of heart rate measurement, in particular to a non-contact heart rate measurement method and device based on Euler image amplification. Background technique [0002] As an important vital sign of the human body, heart rate is an important parameter for evaluating human health. Among them, resting heart rate is an important factor for identifying heart health conditions and other risk predictions for clinical diagnosis. Therefore, daily measurement of resting heart rate will help to assess human health. The monitoring of physical conditions and the prevention of related diseases are of great significance, especially for the prediction of the functional decline and disease risk of the elderly. At present, the electrocardiogram method is the most widely used and highly accurate method in heart rate measurement, but because the sensor device in this type of contact measurement method needs to be in contact with the human s...
