一种基于智能视觉的群体性事件现场态势感知技术

针对群体性事件处置时现场手段多、数据离散和集中监控分析困难等问题,提出一种基于智能视觉的现场态势感知技术.以现场场景、出入口、重要区域的视频图像为核心,通过智能视频分析、安全威胁事件自动识别算法,实现现场态势的自动感知,并建立现场态势的评估模型,并通过具体的实现方案进行验证.结果表明:该技术具有将图像特征的提取和事件识别分离实现的特点,能提高智能视频分析判断的灵活性和可靠性,为指挥人员全面掌控现场态势提供有效的技术手段.

A Live Situational Perception Technique of Group Events Based on Intelligent Vision

Aiming at the problem of multi means, discrete data and difficult analysis in centralized monitoring when the group events is disposed, a technology of live situation perception based on intelligent vision is putting forward. Take the video of live situation, entrances and exits, important area as the core. The technology, which realize the automatic sensing of live situation, generate the evaluation model of the live situation and provide the basis for automatic generation of live safety situation, is realized through video analysis and automatic recognition arithmetic of safety threat events. Through the realization of the program shows that this technology, with the character of separate implement between extracting features from video and event identification, improves the flexibility and reliability of judgment of intelligent video analysis and provides an effective technical means for director's well knowledge of the live situation.
