摘要

开发了一种基于非制冷红外焦平面阵列的红外热成像系统。为降低成本

系统选用具有16 pixel×4 pixel输出像素的红外焦平面阵列探测器MLX90620进行红外辐射强度探测。为获得高分辨率、高质量的红外图像

提出一种将多项式插值与双线性插值相结合的算法

先利用多项式插值提升热像分辨率至64 pixel×16 pixel

再通过双线性插值算法扩充分辨率至256 pixel×64 pixel

对人体进行热成像实验表明:该算法在提高图像分辨率的同时

保留了更多的细节信息。

Abstract

An infrared thermal imaging system based on un-cooled infrared focal plane array technology is presented. To reduce costs

a 16 pixel × 4 pixel infrared focal plane array detector MLX90620 is used to detect the infrared intensity of radiation. An improved algorithm which combines bilinear interpolation and polynomial interpolation is used to get high quality and high resolution infrared image

and the image is interpolated by polynomial interpolation

to improve its resolution to 64 pixel × 16 pixel

then bilinear interpolation method is adopted to advance image resolution from 64 pixel × 16 pixel to 256 pixel × 64 pixel. Experiments on human body shows that the algorithm can not only improve image resolution

but also keep more details.
