用红外热像仪分析人体的温度分布和病灶

Analysis of Temperature Distribution and Lesions of Human Body by Infrared Thermal Imager

非致冷红外热像仪具有价格低、重量轻、功耗低、体积小、性能可靠等特点。本文采用微测辐射热计非致冷焦平面红外热像仪对人体温度的分布情况进行了研究。由于红外灰度图像的对比度较差以及各个部位的红外图像的灰度范围不同,对微测辐射热计非致冷焦平面红外热像仪得到的红外图像进行了自适应阈值伪彩色图像处理,处理结果为分析病灶的位置和大小提供了方便。

Uncooled infrared thermal imagers have the features of low price, low weight, low power dissipation, small size and reliability etc.. An uneooled infrared thermal imager with an infrared micro- bolometer focal plane array is used to analyze the temperature distribution and lesions of human bodies. Because infrared grey scale images have lower contrast and the grey scales of the images of different parts of a human body are different, the pseudo-color images obtained by the infrared thermal imager are processed by using an adaptive threshold processing method. The processing results are of great convenience for analyzing the location and size of lesions.
