The invention discloses an artificial-intelligence-based abnormal eyelid movement evaluation system. The system comprises an examined object obtaining module, an eye and specific part positioning module, a TSN model, a probability output module and an evaluation module; the examined object obtaining module is used for obtaining a facial video which is obtained from a facial movement video of the input examined object and only contains the examined object, the eye and specific part positioning module is used for positioning the eye and specific part of the facial video and obtaining an eye movement video and a specific part linkage video which only contain the examined object, the TSN model is used for processing the eye movement video and the specific part linkage video and outputting movement signals of eyes and specific parts, the probability output module is used for outputting probability signals appearing when a computer judges that eyelid movement is abnormal in each frame, and the evaluation module is used for obtaining the abnormal level according to the probability signals appearing in abnormal eyelid movement and an abnormal eyelid movement probability judging mechanism.Accordingly, universal acceptability, convenience, accuracy, objectivity and repeatability are achieved, and the clinical applicability is high.
