Embodiment

[0037] Such as Figure 1-3 As shown, the method for predicting changes in body temperature based on heart rate estimation and respiration estimation includes the following steps:

[0038] Step S1: Calculate the heart rate h and respiration rate b from the data collected by the camera;

[0039] Step S2: Push the heart rate h, breathing rate b and the corresponding time t into the stack p, that is, p={[h1, b1, t1], [h2, b2, t2], ..., [hn, bn , tn]}, where h1 and b1 represent the heart rate and respiration rate corresponding to time t1 respectively, and hn and bn represent the heart rate and respiration rate corresponding to time tn respectively;

[0040] Step S3: Find the latest data set S from the stack P, that is, the data set S is a subset of the stack p, and calculate the heart rate value hb_s in the most concentrated heart rate data set of S through the Meanshift algorithm, as the effective value of the measured heart rate , calculate the most concentrated respiration rat...

Abstract

The invention relates to the technical field of human body-temperature prediction, in particular to a human body-temperature change prediction method based on heart rate estimation and respiration estimation, which is used for solving the problem that human body-temperature cannot be predicted more accurately. The method comprises the following steps: S1, heart rate h and respiration rate b are calculated; S2, the heart rate h, the respiration rate b and the corresponding time t are input into a stack p; S3, a data set S is found in the recent time from the stack P, and a heart rate value hb_swith the most concentrated center rate data set in the S is calculated through a Meanshift algorithm to serve as a measured heart rate effective value; a respiratory rate value hb_l with the most concentrated respiratory rate data set in the S is calculated through a Meanshift algorithm to serve as a measured respiratory rate effective value; S4, the body temperature offset is calculated according to the formula dT = f (hb_s, hb_l, age, t), wherein age refers to age, and f is a data model created by a large amount of data; and S5, the body temperature offset dT and the basic body temperatureTO are added to obtain a final body temperature T, that is, T=TO+dT. Therefore, the human body body-temperature can be predicted more accurately.

Description

technical field [0001] The present invention relates to the technical field of human body temperature prediction, and more particularly relates to a method for predicting changes in human body temperature based on heart rate estimation and respiration estimation. Background technique [0002] Accurately measuring the physical temperature of the human body has positive guiding significance for human health. Usually, we use a thermometer to measure the body temperature of the human body. The thermometer is successfully developed on the basis of the thermometer to measure the physical temperature of the human body. Measuring the temperature of the human body can not only diagnose the occurrence of diseases, but also play an active role in preventing and warning some major diseases or hidden health risks hidden in the body. Although the thermometer is widely used to measure the body temperature of the human body, the thermometer needs to be in contact with the human body to meas...
