高分辨カ红外热图像重建算法的进展及研究

由于探测器阵列有限以及像元尺寸对成像的影响，红外热成像系统的图像分辨力较低，往往难以满足实际应用的更高要求。本文介绍了国际上较为流行的两种提高红外热图像分辨力的方法：微扫描法和不受控的微扫描法，并提出用微扫描与基于Markov约束的Poisson-MAP超分辨力图像复原算法( MPMAP)结合重建高分辨力红外热图像的方法，模拟分析表明该算法具有提高热成像分辨力的效果。

Research and Recent Advance of High Resolution Infrared Image Reconstruction Technology

The finite detector arrays and finite individual detector sizes oi infrared imaging systems con?tribute to the nonideal sampling of the scene information. Aliasing will occur. This aliasing can significantly degrade the image quality, causing low resolution of acquired images. Two resolution improved techniques introduced here, are referred to as microscanning and uncontrolled-microscanning. On the basis of our study on image super-resolution, one new reconstruction technique using combination of microscanning and super- resolution algorithms was presented. The technique using MPMAP algorithm is demonstrated by experi?mental results and can significantly improve infrared system’s resolution.
