The invention provides a multi-
modal fusion fatigue screen monitoring recognition and reminding method and
system, and the method comprises the steps: data collection: collecting the visual data of a screen monitoring person in real time, and synchronously collecting the physiological data; multi-
modal data fusion: adopting a feature weighted fusion method based on an
entropy weight method to adaptively distribute weights and generate a fusion fatigue index FFI by quantifying dynamic information entropy of each visual data and physiological data; fatigue grade classification: realizing three-level fatigue state judgment based on a fusion fatigue index FFI obtained by multi-
modal data fusion and a dynamic
decision tree model; and dynamic intervention: based on a fatigue grade
classification result, adopting a double-channel intervention mechanism of bracelet touch alarm and automatic
telephone call value length. When fatigue and inattention of a monitoring screen watchman occur, the monitoring screen watchman can be timely and accurately identified and a reminding intervention mechanism is started, so that the continuity and the safety of the monitoring screen work are ensured, and bad safety production events caused by human reasons are avoided.
