Abstract

The invention provides a psychological state recognition method and equipment based on an fundus image. The method comprises the following steps: acquiring a retinal blood vessel diameter parameter and the fundus image; extracting feature information from the fundus image by using a feature extraction network; obtaining fused feature information according to the feature information and the parameters; and identifying the fused feature information by using an output network to obtain an identification result about the psychological state.

Problems solved by technology

[0003] There are two main types of existing psychological state assessment schemes. The first type is to analyze the psychological state through human physiological signals, such as heart rate signals and blood oxygen saturation signals. These physiological signals are susceptible to external interference, such as human emotions. When it is unstable, there will be obvious changes, resulting in inaccurate analysis results; the second type is to use the psychological evaluation scale to evaluate the psychological state, which is easily affected by subjective factors. In order to improve accuracy, a large number of questions are usually set in the scale and answer options, the testees need to spend a lot of time answering the questions in the scale, resulting in relatively low evaluation efficiency
