Problems solved by technology

[0005] However, the disadvantages of this method are more obvious:
[0006] a. Seriously affected by light, wearing glasses or not, individual differences in eye size, individual reactions and habits vary greatly;
[0007] b. It is difficult to find features that are robust and adapt to background changes;
[0008] c. The camera captures the user's expressions and actions, which are the external expressions of emotions and are easily hidden and disguised by the user
[0009] In summary, in the prior art, there is no simple, effective and accurate method for judging the emotions of the human body.

Embodiment 1

[0062] Embodiment 1 of the present invention provides the first preferred embodiment of the emotion judgment method, such as figure 1 Shown is the flow chart of the first embodiment of the emotion judgment method provided by the embodiment of the present invention.

[0063] refer to figure 1 , a kind of emotion judgment method that the present embodiment provides, this method comprises the following steps:

[0064] S1. Obtain the electrocardiographic signal of the measured object, and calculate the time domain index according to the adjacent R-wave time interval of the electrocardiographic signal as the first reference index;

[0065] S2. Collect the electrodermal signal of the measured object, and calculate the second reference index according to the peak number, peak height and highest peak amplitude of the electrodermal signal;

[0066]S3. Judging the emotional state of the measured object according to the variation trends of the first reference index and the second refer...

Embodiment 2

[0081] Embodiment 2 of the present invention provides the second preferred embodiment of emotion judgment method, such as figure 2 Shown is the flow chart of the second embodiment of the emotion judgment method provided by the embodiment of the present invention.

[0082] refer to figure 2 , based on the above-mentioned embodiment, the electrocardiographic signal of the measured object is obtained, and the time domain index is calculated according to the adjacent R-wave time interval of the electrocardiographic signal, as the first reference index specifically includes:

[0083] S11. Acquiring continuous ECG signals of the measured object;

[0084] S12. Taking out a complete ECG signal waveform from the continuous ECG signal;

[0085] S13. Determine the R wave peak point in the ECG signal waveform;

[0086] S14. Calculate and obtain the time interval of adjacent R waves according to the time series acquisition frequency.

[0087] In the above step S11, if Figure 7 As s...

Embodiment 3

[0093] Embodiment 3 of the present invention provides the 3rd preferred embodiment of emotion judgment method, as image 3 Shown is the flow chart of the third embodiment of the emotion judgment method provided by the embodiment of the present invention.

Abstract

The embodiment of the present invention discloses a method and device for judging emotions, wherein the method includes: acquiring the electrocardiographic signal of the subject to be measured, and calculating the time domain index according to the time interval of adjacent R waves of the electrocardiographic signal as the first reference index ; collect the electrodermal signal of the measured object, and calculate the second reference index according to the number of peaks, the peak height and the highest peak amplitude of the electrodermal signal; emotional state. Firstly, the present invention provides an efficient and low-cost emotional judgment approach, and secondly, realizes simple, effective and accurate judgment on human emotions, and improves user experience.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical technology, in particular to an emotion judgment method and device. Background technique [0002] Emotion is a general term for a series of subjective cognitive experiences, and it is a psychological and physiological state produced by a variety of feelings, thoughts and behaviors. [0003] In the prior art, the emotion recognition method mainly uses a camera to obtain user images, and judges through image processing and recognition technologies, specifically: [0004] An image processing method based on video recording equipment such as a camera, that is, through the video captured by the camera, image processing is performed frame by frame to find effective features representing emotions, and then realize emotion recognition. [0005] However, the disadvantages of this method are more obvious: [0006] a. Seriously affected by light, wearing glasses or not, individual differenc...
