Emergency target information acquisition method and device based on video, equipment and medium

Abstract

The invention provides a video-based emergency target information acquisition method and device, equipment and a medium. The method comprises the following steps: acquiring videos of a plurality of different visual angles; acquiring a key frame image of each video; acquiring a key frame image containing the emergency target, and performing data extraction for the emergency target on the key frame image containing the emergency target to obtain emergency target data; associating the emergency target with the videos, the key frame images and the emergency target data of a plurality of different visual angles to obtain an emergency target information base; and acquiring corresponding emergency target information from the emergency target information base according to the information acquisition requirement. According to the emergency target information acquisition method and device based on the video, the equipment and the medium, the emergency target is associated with the videos of multiple different visual angles, the key frame images and the emergency target data, so that information of different dimensions of the emergency target is obtained, data sources of rich emergency decisions are provided hierarchically, and the information acquisition efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of information analysis and information processing, and in particular relates to a video-based emergency target information acquisition method, device, equipment and medium. Background technique [0002] As an important part of smart city construction, real-time surveillance video has the important characteristics of huge data scale, complex data processing, low data value density, and fast data update and change. Taking a single camera in a real-time monitoring system as an example, the semantic content of the monitoring video screen changes rapidly in seconds. Therefore, analyzing and understanding the semantic content of large-scale real-time surveillance video plays an important role in emergency management and decision support in various complex scenarios. [0003] The current acquisition technology for emergency intelligence mainly includes intelligence analysis and processing of text information, fus...

Problems solved by technology

[0004] At present, intelligence analysis technology is mainly aimed at traditional information sources such as network information resources and document information resources. Traditional information sources are difficult to meet the comprehensive emergency decision-making problems in the smart city scene. For the single data source intelligence organization and single analysis technical means, for real-time video in-depth Hierarchical exploration and analysis and generation of key intelligence are still in their infancy, and there is no method that can effectively use image information in real-time surveillance video to obtain intelligence
