Research and development of general technical specifications for video surveillance systems in the coal mining industry

  • 摘要: 为提升煤矿工业视频监控系统在现代化矿井复杂应用场景下的环境适应性、智能分析可靠性,除图像监视功能外,系统应增加:① 视频图像质量自诊断机制,对视频图像质量和云台镜头远程控制的有效性进行自动检测和诊断。② 多层级智能视频分析(IVA)体系,包括目标检测、目标识别、行为识别、事件检测等。③ 可配置IVA框架,支持根据需求选择和配置IVA功能。④ 结构化视频描述与索引,支持对IVA结果进行自动描述,以及基于IVA结果等信息建立索引。⑤ 跨系统报警联动,具备报警联动数据交互接口,发送IVA结果等信息至其他设备或系统。系统主要IVA功能应通过最大误差、误报率、漏报率、IVA延迟等指标进行量化,其中最大误报率不高于5%,漏报率不高于10%,IVA延迟不大于2 s。设计多场景模拟试验综合验证系统性能,主要包括:① 采用视频质量干扰模拟与主观评价机制验证视频图像质量自诊断功能和系统图像质量。② 构建测试视频导入、测试视频翻拍、场景模拟三重测试体系评估IVA功能。③ 采用总带宽占用量计算或最大数量视频信号接入测试方式验证系统最大容量。

     

    Abstract: To enhance the environmental adaptability and reliability of intelligent analysis of video surveillance systems in the coal mining industry under complex modern mine scenarios, in addition to image monitoring functions, the system should include: ① a video image quality self-diagnosis mechanism that automatically detects and diagnoses the quality of video images and the effectiveness of remote control of the PTZ lens. ② a multi-level Intelligent Video Analysis (IVA) system, including target detection, target recognition, behavior recognition, and event detection. ③ a configurable IVA framework that supports selecting and configuring IVA functions according to needs. ④ structured video description and indexing, supporting automatic description of IVA results and the establishment of indexes based on IVA results and related information. ⑤ cross-system alarm linkage, equipped with data interaction interfaces for alarm linkage, sending IVA results and other information to other devices or systems. The main IVA functions of the system should be quantitatively evaluated by indicators such as maximum error, false alarm rate, missed detection rate, and IVA latency, with the maximum false alarm rate not exceeding 5%, missed detection rate not exceeding 10%, and IVA latency not exceeding 2 seconds. Design multi-scenario simulation tests to comprehensively verify system performance, mainly including: ① verification of video image quality self-diagnosis function and system image quality through video quality interference simulation and subjective evaluation mechanisms. ② evaluation of IVA functions by establishing a triple test system including test video import, test video re-shooting, and scenario simulation. ③ verification of system maximum capacity by total bandwidth occupancy calculation or maximum number of video signal access tests.
