【摘要】 介绍了红外探雷技术和红外探雷系统的现状及发展,研究了红外探雷的热传导模型和雷场红外图像的处理方法。在分析红外探雷系统结构和影响红外探雷因素的基础上,提出了一种红外探雷的三维热传导模型,该模型通过分析地雷和掩埋环境之间不同的热量特性来对目标进行探测。在建立地雷的红外辐射特性模型的基础上,分别对该热传导模型的初始条件和边界条件进行了分析讨论,模拟仿真生成掩埋地雷区域地表的温度场分布,研究了掩埋有地雷区域和无地雷区域地表温度差变化,并分析了其温度场的分布特性和影响其为温度分布的因素。最后,分析了雷场红外图像特征,研究了有针对性的图像处理方法,总结出一般的处理规律。
【Abstract】 In this paper, the application, status, development of infrared landmine detection and infrared landmine detection system are discussed. Infrared thermal conduction modelling of landmine detection and minefields infrared image processing methods are researched. After analyze infrared landmine detection system and factors affecting infrared landmine detection, propose a new three-dimensional thermal modelling of landmine detection. The detection principle of the landmine detection modelling relies on the difference between thermal characteristics of the landmines and those of the background. Based on thermal modelling for buried landmine detection, analyze the initial and boundary conditions. The temperature distribution around the district is generated by simulation. Surface temperature difference changes of the district is analyzed. The characteristic of the minefield infrared imaging is analyzed, the proper method of the image processing is researched, then generic regulation, method and process is summarized.
