The invention discloses an event detection method, device and system based on tunnel thunder view data fusion in the field of tunnel detection. The method comprises the steps of carrying out the classification and screening of radar data, and obtaining a radar data target detection point, performing target detection on the video data to obtain a video data detection target, based on a radar data detection target and a video data detection target, conducting decision-level fusion through a fusion algorithm of a detection frame cross ratio, and acquiring a target fusion result, wherein the target fusion result comprises the speed, the position information and the number of the targets and the distance between the targets; and the target comprises a vehicle target and a non-vehicle target, and according to the target fusion result, carrying out traffic event detection judgment to obtain a traffic event detection result. The fused traffic characteristic information is analyzed, whether a traffic event occurs is judged, the type of the traffic event is output for event early warning, and the detection precision of the traffic event is improved.
