摘　　要：显微热成像技术根据温度变化对细微目标进行热成像,是国内外光电成像领域重要的研究方向。由于加工技术精度有限,前期研制的光学微扫描显微热成像系统存在扫描位置误差,该误差使基于微扫描图像直接融合形成的图像质量下降。提出一种结合图像预处理思想、微扫描原理和通过计算像素相关度进行微扫描图像插值重建的算法。仿真及实验表明:方法能改善图像重构质量,提高系统的空间分辨力,还可应用于其他带有微扫描的光电成像系统以提高其系统性能。The thermal microscope imaging technology can obtain non-contact imaging for fine target objects according to temperature changes,which is an important research direction in the field of photoelectric imaging technology.Due to the limited accuracy of the processing technology at present,the scanning position error will occur during the operation of the optical micro-scanning thermal microscope imaging system developed in the early stage.It will have a certain effect on the subsequent image embedding reconstruction,and the resolution of the reconstructed image is decreased.To solve the problem,a method of micro-scanning error correction by combining image pre-processing thought,micro-scanning principles,and calculating pixel-correlation is proposed.The results of simulation and experiment show that this method can improve the quality of image reconstruction and the spatial resolution of the system.The method can be directly applied to other photoelectric imaging systems to improve its performance.
