Abstract

The invention discloses an event detection method and device, electronic equipment and a storage medium. The city management event detection method comprises the following steps: acquiring video stream data of a preset scene area, and acquiring at least one key frame image according to the video stream data; detecting whether a scene target corresponding to the event exists in the at least one keyframe image or not; obtaining the actual position and / or the stay duration of the scene target in the preset scene area; and judging whether the event corresponding to the preset scene area occurs ornot according to whether the scene target exists or not and according to the actual position and / or the stay duration. According to the invention, whether the corresponding event occurs or not is judged through the recognition of the scene target in combination with the space-time information of the scene target in the preset scene area, so that the misjudgment rate is reduced, and the detectionaccuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of computer networks, and in particular, to an event detection method, device, electronic equipment and storage medium. Background technique [0002] At present, with the development of computer vision recognition technology, the recognition technology of fixed characteristic targets such as faces, human bodies, motor vehicles, and non-motor vehicles is becoming more and more mature, and it is used more and more in the field of security, and the application scenarios are becoming more and more complicated. In the field of urban management, computer vision recognition is more inclined to object, behavior and event recognition, that is, scene detection and recognition. [0003] Under the existing technical conditions, through the item recognition technology, the identified single target (person, vehicle, object, animal, etc.) or multiple target combinations (target 1 + target 2 + target 3 + ... + tar...
