摘要
综述了红外信号的分析方法和应用现状,通过对比图像分析、模型分析、四点算法、相关算法和傅里叶变换等常用的红外分析方法的优缺点,认为先通过小波变换等方法提取有用信号,再根据不同的红外信号采取不同的分析方法是最切实可行的,并对红外信号分析的发展方向进行了展望。
In this paper the analysis methods and application status of infrared thermography are reviewed. By comparing the commonly used analysis methods of infrared thermography,such as image analysis,model analysis,four algorithms,the related algorithm and Fourier analysis,it can be known that extracting the useful signal through methods such as wavelet transform,and adopting different analysis methods according to different infrared signal is the most practical and feasible method. Finally,the development direction of the infrared signal analysis is discussed.
