The invention belongs to the field of
big data processing, and particularly relates to a video
stream event detection and
analysis method and device, a medium and a program product, an event in a video
stream is detected in real time, the event duration of the event in the video
stream is determined, whether the event is a target event or not is determined according to the event duration, and if the event is the target event, the video stream event is detected. If yes, obtaining event triggering
time information of the target event, determining a plurality of video frames corresponding to the target
event based on the event triggering
time information, determining a target area of the target event in each video frame according to
spatial distribution characteristics of the target event in the plurality of video frames, and performing semantic analysis on the target event in the target area; according to the method, the target event needing semantic analysis is screened based on the event duration, and the target area is accurately positioned in combination with the trigger time and
spatial distribution characteristics, so that the efficiency of video stream event detection and analysis is improved.
