Provided in the present application are a user fatigue state recognition method, an apparatus, a terminal device and a medium, used in the technical field of data processing. The method comprises: collecting face video of a user while driving during a first pre-determined time period, and processing the face video, obtaining a first blink frequency and a first number of times eyes were closed of the user in the first pre-determined time period; inputting the first blink frequency and the first number of times eyes were closed into a pre-generated fuzzy controller, obtaining a real-time fatigue level of the user, the fuzzy controller being generated according to pre-collected blink frequency sample data and sample data of a number of times eyes were closed of the user in a pre-determined time period, and corresponding fatigue level sample data in the predetermined time period, and being used to recognize a fatigue level of a user; if the real-time fatigue level of the user is higher than a pre-determined level threshold, outputting a safety alert to the user. Embodiments of the present application ensure accuracy of recognizing a fatigue state of a user while driving, maintaining user driving safety.
