摘　　要：周界入侵探测对安防工程具有重要意义，研究了一种新型的智能入侵探测系统并加以应用。该系统由红外图像提取与前置处理模块、数据传输模块、智能分析与自动报警模块三个功能模块组成，主要研究内容包括：基于二维离散小波变换算法实现红外图像增强；基于对提取目标及预设模型的智能判断，实现分析与报警功能的联动；创新性地提出红外热敏摄像头布局方案，高效地实现了周界入侵探测的全覆盖。该新型智能入侵探测系统在实践中进行了运用，探测效果满足要求，具有较好的实用价值与经济效益。An innovative intelligent intrusion detection system is analyzed and applied, consisting of infrared image collection and pre-processing module, data transmission module, intelligent analysis and automatic alarm module, in- frared imagery pre-processing is achieved through 2-D discrete wavelet transform algorithm, considerably minimizing noises and enhancing details. Synergistic action of intelligent analysis and automatic alarm are achieved through intelli- gent comparison between extracted imagery and target models. Innovative deployment plan of thermal infrared cameras is applied to avoid blind zone of intrusion detection. Through mix deployment of clockwise and anti-clockwise camer- as, full coverage of security perimeter is achieved efficiently. The proposed intelligent intrusion detection system is ap- plied, and its results are acceptable, being of great efficiency and economic advantage.
