Abstract

The embodiment of the invention provides an event information acquisition method and device. The scheme comprises the steps of obtaining a to-be-detected video; determining all targets in each frame of image in the to-be-detected video and types of all the targets; determining multiple pieces of triple information corresponding to each frame of image according to the types of all targets in each frame of image, the type of a preset action executor, the type of a driven target and the type of an interaction tool; intercepting at least one continuous image sequence corresponding to each piece oftriple information from the to-be-detected video; and respectively inputting each continuous image sequence corresponding to each piece of triple information into the behavior event detection model to obtain event information corresponding to each piece of triple information. By applying the technical scheme provided by the embodiment of the invention, the hysteresis problem existing in event information acquisition is solved, and the event information acquisition efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of video surveillance, in particular to a method and device for acquiring event information. Background technique [0002] Event information acquisition refers to monitoring whether the target in the video has a specific behavior, and recording the relevant video information of the specific behavior of the target. [0003] At present, the event information acquisition method is mainly based on simple rules set. For example, for behavioral events such as a vehicle running a red light and failing to yield to pedestrians, rules such as red light time period, red light and vehicle appearing in the same image, and / or the positional relationship between pedestrians and vehicles in the image can be set. Based on the rules set above, after the image is captured, target detection is performed on the image to determine whether the target in the image matches the rules set above. If they match, it is determ...
