摘　　要：为提高已研制光学微扫描显微热成像系统的空间分辨力,基于改进的频域图像配准技术和凸集投影超分辨力算法,提出了显微热成像系统光学微扫描超分辨力图像处理方法。给出了该方法的原理及步骤,采用不同重构方法行了仿真研究,给出了评价参数和结论。利用光学微扫描显微热成像系统采集低分辨力显微热图像序列进行了超分辨力处理实验,实验结果表明本文提出方法的有效性,光学微扫描显微热成像系统的空间分辨力得到提高从而可满足需要高分辨力显微热分析的场合。该方法还可以应用于其它不可控光学微扫描成像系统中,具有广泛的应用前景。In order to improve the spatial resolution of the designed optical plate rotating microscanning thermal microscope imaging system,based on the improved frequency-domain image registration techniques and projections onto convex sets（POCS）,a method of optical microscanning superresoluion reconstruction for the thermal microscope imaging system was presented.The working principle and the method were analysised.Different reconstruction methods were applied to reconstruct the visible image,moreover the evaluation parameters were given.Results of simulation and real thermal microscope images processing showed the availability of the method.The image spatial resolution and quality were improved and the detail was more.The system can be applied into many systems which need high spatial resolution minute thermal analysis.The algorithm can also be applied into the uncontrolled optical microscanning imaging systems and has wide application prospect.
