Real-time scoring system and method for gastrointestinal endoscope operation level

The invention belongs to the medical technology assistance field, and relates to a real-time scoring system and method for gastrointestinal endoscope operation level. The real-time scoring system forgastrointestinal endoscope operation level includes a client and a server side, wherein the client is used for monitoring and uploading images collected by a current gastrointestinal endoscope devicethrough the network, the time of operation, and the number of endoscope reversing and return, receiving and displaying the results of scoring in real time; and according to the gastrointestinal endoscope images collected from the client, the server side scores the operation of a doctor by analyzing the features of parts, the operation time, and the visual field definition index, and feeds the result back to the client. Through the real-time scoring system for gastrointestinal endoscope operation level, the gastrointestinal endoscope operation process of the doctor is scored and displayed on the client; the doctor's operation level is quantitatively expressed objectively and directly; and the doctor is more aware of the skill level and stimulating the endoscope physicians to learn from eachother so as to constantly improve the level of operation.
