Abstract

The invention relates to an early warning method and device based on video analysis, electronic equipment and a storage medium, and the method comprises the steps: carrying out the target detection ofa collected video stream of a preset geographic region, and determining a first image frame, including a target, in the video stream; when the state of the video stream is an early warning silence state and the first image frame is detected for multiple times within a preset first duration, changing the state of the video stream into an early warning activation state, wherein the early warning silence state is used for indicating that no target exists 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 when the video stream is in the early warning activation state, sending early warning information for the video stream. According to the embodiment of the invention, the target recognition accuracy can be improved, and reasonable early warning is effectively realized.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a video analysis early warning method and device, electronic equipment and a storage medium. Background technique [0002] The targets that relevant departments need to pay attention to in social security work include: banners containing sensitive content appearing on the street (hereinafter referred to as sensitive banners), fireworks, 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 proposes a video analysis-based early warning method and device, electronic equipment, and a storage medium, whic...
