【摘要】 随着红外热像仪越来越广泛的在军事和民用方面的应用,用户对其采集的红外热图像的处理与分析功能也提出了更高的要求,因此开发出功能强大的、符合规范的红外热像仪图像分析系统软件具有理论与实践意义。本文对红外图像的文件格式、显示、处理、分析以及人脸识别的方法等相关问题进行了研究,开发出了红外图像分析处理系统组件,并应用于各种不同用途的红外图像商业软件中。分析了红外热像仪测温原理与红外图像的特点,提出了一种新的红外图像规范。新的红外图像规范包含了更多的图像信息,并且可以储存分析数据,也具有一定的可扩展性。根据新的红外图像规范,实现了红外图像的数据转换、图像测温、图像增强、图像处理以及局部放大等红外测温技术的基础服务。研究了现有的红外图像软件的功能和不足,增强了面向红外应用的辅助分析功能,实现了分析图形的鼠标自动拾取以及编辑撤销等方法。采用最新的软件规范、标准和工具,运用面向对象的设计方法与UML建模方法,开发出了红外图像分析系统组件,并将组件成功应用于多个红外图像应用软件。在上述研究成果与现有红外图像识别技术的基础上,提出了一种基于支撑向量机的红外热图像的人脸自动识别方法,提高了红外热像仪的自动化水平,扩大了热像仪应用范围。实验证明了其有效性。更多还原

【Abstract】 With the wider use of infrared camera,the processing and analyse method of thermal infrared image which is obtained by the infrared camera is more and more important. A good infrared image software has great significance both in theory and in practice. Based on research on file format, display, processing, analyse and face recognition method of infrared image, a infrared image system component is developed which has been used in several commercial software successfully.Based on research on the character of both infrared image in existence and BMP file , a new format of infrared image file is provided. It is standard, has more information and counld be easily extended. The algorithm of display, converting, measure, enhancement, processing and part amplifying the new infrared image file are realized.After study the function and shortage of the old infrared software, using the newest software criterion and developing tool, based on Object-Oriental method and UML, a infrared image system component is developed. It enhance the function of image analyse, which provide a method of picking up the graph. It has been used in several application software.On the basis of the achivements mentioned above, a method to detect human faces in infrared images based SVM algorithm is provided. It improves the level of automation of infrared camera and extends the range of use. The experiment shows the effect.更多还原
