引言智能视频分析技术起源于计算机视觉技术,它综合应用图像增强处理等技术,在实现目标与背景分离的基础上,通过将目标特征信息与预先设置的模板或规则进行比对,自动识别感兴趣的目标、行为、事件或数据并产生报警,必要时可自动跟踪异常目标并联动其他安防设施,显着提高了安全防控整体效率和能力。同时利用安防智能视频分析技术可在海量历史视频信息中实现基于时间、地点以及语义特征描述的智能化查询搜索。
Introduction Intelligent video analysis technology originated in computer vision technology, which integrated application of image enhancement technology, based on the separation of the target and the background, by the target feature information and pre-set templates or rules to automatically identify the interest Of the target, behavior, incident or data and generate an alarm, if necessary, can automatically track abnormal targets and other security facilities linked to significantly improve the overall safety control efficiency and ability. At the same time, the intelligent video search technology based on security intelligent video analysis can be used to realize intelligent query search based on time, place and semantic feature description in massive historical video information.
