The invention discloses a method, terminal, equipment and system for evaluating a psychological state of a person serving a sentence. According to input fingerprint information, a to-be-tested psychological index corresponding to the fingerprint information is extracted, and an animated game scene corresponding to the current to-be-tested psychological index is selected; a VR experience scene corresponding to the current to-be-tested psychological index is also selected; a first physiological signal of the to-be-tested person serving the sentence under the animated game scene is collected; a second physiological signal and first behavior signal of the to-be-tested person serving the sentence under the VR experience scene are collected; the collected signals are preprocessed; the preprocessed signals are subjected to feature extraction to obtain a feature vector; the feature vector is subjected to feature vector fusion, the fused feature vector is input into a pre-trained prediction model, and the prediction model outputs a classification result of the psychological state of the to-be-tested person serving the sentence.
