摘要
热成像测温系统中,提出用线性灰度变换的方法,解决信号源动态范围大,而显示输出动态范围小的矛盾。不仅使图像丰富清晰,通过相应的公式可非常简单的计算出温度,而且图像存储后还可进行后期温度分析。对这种方法的不足也做了分析,并提出了解决方案。
The paper described the linear gray wide dynamic range of IR source and narrow level transformation to solve the contradiction between the out put dynamic range displayed in the thermal imagery temperature measurement system. After transformation, not only the image gets clear, through the formula we can get the temperature easily, but also we can analyze the temperature in later stage after Image is memorized. We made analysis to this method＇s shortcomes, and proposed the solution.
