视频质量诊断技术是采用先进的视频图像分析算法,对监控设备的视频流进行智能分析,从而间接判断出设备当前运行状态是否正常的技术。当前各大监控厂商陆续推出了多款视频质量诊断产品,如大华股份、海康威视、捷尚、字视科技等,总结起来涉及的功能及产品形态大致相同,以大华股份的视频质量诊断产品为例,该产品可以实现对监控设备常见的异常抖动、画面条纹、画面模糊、偏色、亮度异常、对比度异常、冻结、丢失、噪声等机器故障及恶意遮挡、恶意变化监控场景的行为做出准确判断,还可以对监控设备因为网络异常等原因导致的设备断线、取流异常、码率是否达标等问题进行准确定位,通过配套应用软件的汇总统计,可以将故障设备存在的问题清晰展现给用户,便于进行快速精确定点检修,从而保证视频监控系统的长期正常有效运行,也大大减轻了维护监控设备的工作量。
Video quality diagnostic technology is the use of advanced video image analysis algorithms, video surveillance equipment for intelligent analysis, which indirectly determine the current operation of equipment is normal technology. At present, the major monitoring manufacturers have launched a number of video quality diagnostic products, such as UOB shares, Hikvision, Czech Republic still, as the word technology, summed up the functions and products involved in roughly the same form to UOB shares of the video For example, the product of quality diagnosis, such as abnormal jitter, picture streaks, blurred pictures, color cast, abnormal brightness, abnormal contrast, freezing, loss, noise and other machine faults, malicious occlusion and malicious change monitoring scenes Behavior to make accurate judgments, but also on the monitoring equipment due to network anomalies and other reasons lead to equipment disconnection, take the flow anomaly, the code rate is standard and other issues for accurate positioning, through the application of software summary statistics, faulty equipment can exist The problem is clearly displayed to the user for quick and accurate fixed-point overhaul, so as to ensure the long-term normal and effective operation of the video monitoring system and greatly reduce the workload of maintaining the monitoring equipment.
