基于图像拼接方法的计量过程数字化记录

摘要

To remove the perspective error which recorded by single CCD, a new method based on SIFT was used, which provided an accurate mosaic image of indication of the standard and measured instrument. Finally, The experiment is presented to illustrate the effectiveness and versatility of our approach.%　　针对单幅CCD相机所获指针式表盘图像存在的视角误差问题，提出了基于SIFT(尺度不变特征变换)的图像拼接方法，将分别准确获取的标准器与被检器示值图像进行无缝拼接，并通过实验验证了方法的有效性和可行性。
