Emotion recognition method based on infrared thermal imaging

The invention discloses an emotion recognition method based on infrared thermal imaging, and relates to the field of image recognition. The method comprises three parts of data set construction, model training and emotion recognition, and specifically comprises the following steps: firstly, constructing a data set, and dividing training data and test data; training a model which takes ResNet as a trunk and comprises a data enhancement module, a feature extraction module, a target detection module and an emotion classification module; and finally identifying the emotion to obtain an identification result. According to the following principles, infrared thermal imaging can collect human body surface temperature information and further recognize emotions: (1) human body emotion changes are accompanied by physiological reactions such as hormone secretion, muscle activity, capillary circulation changes and the like, so that the heat dissipating capacity of the body epidermis changes; (2) the infrared thermal imagi
