针对光学微扫描显微热成像系统微扫描过程中微位移位置不准确,空间分辨力低的问题,本文提出一种自适应零点定标方法.该方法将图像配准算法作为计算图像之间的微位移的工具,并利用几何原理进行微扫描零点位置的自适应标定.利用望远模式红外图像模拟自适应零点定标前后实际系统,采用不同重构方法进行了仿真研究;完成了自适应零点定标前后实际系统采集的欠采样显微热图像序列的重构对比实验.结果表明利用该方法完成自适应零点定位后,可有效提高过采样重构图像质量,提高了系统空间分辨力.此方法还可以应用到其他光电成像系统中.

In order to accurately calibrate micro scanning position and improve the spatial resolution of micro thermal imaging systems,the zero of micro scanning should be determined. The image registration algorithm was used to calculate the micro-displacement, and then a new adaptive zero calibration was presented based on geometric principle. Using telescopic thermal image to simulate the real system, different reconstruction methods were adopted to construct the simulation image and the real thermal microscope image before and after adaptive zero calibration. The results show that the method significantly improves the oversample reconstructed image quality, and increases the system spatial resolution. This method can also be used in other electro-optical imaging systems.
