Abstract

The invention relates to an early warning method and apparatus based on video analysis, an electronic device and a storage medium. The method comprises the steps of: performing target detection on a captured video stream of a preset geographic area, and determining a first image frame comprising a target in the video stream; when the state of the video stream is an early warning silence state, andthe first image frame is detected for multiple times within a preset first time length, changing the state of the video stream into an early warning activation state, wherein the early warning silence state is used for indicating that the target does not exist in the preset geographic area, and the early warning activation state is used for indicating that the target exists in the preset geographic area; and in the case that the first image frame is detected for multiple times within a preset second time length after the video stream enters the early warning activation state, sending early warning information for the video stream. By adopting the early warning method and apparatus provided by the embodiment of the invention, the target recognition accuracy can be improved, reasonable early warning is effectively realized, and the trouble caused by excessive early warning to users is reduced.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a video analysis-based early warning method and device, electronic equipment and storage media. Background technique [0002] In the daily urban governance work, the targets that need to be paid attention to include: road garbage, shared bicycles illegally parked or placed in a mess, illegal operation of umbrella sheds, illegal covering of soil at the entrance of the construction site, improper stacking of building materials on the construction site, etc. Usually, based on the video analysis algorithm, the detection and recognition of the target in the image frame, and the early warning method based on the detection result of the single frame detection, the accuracy of target recognition is low, resulting in a high frequency of warning and many false positives, which cannot Realize reasonable early warning. Contents of the invention [0003] The present disclosure p...
