| 摘 要： | 红外热波无损检测中，红外热波空间序列图像间的变化主要是位移和小幅度旋转。针对该特点，在可能的旋转角度范围内，利用傅里叶变换的相位相关技术判定旋转的角度和平移量，实现图像的配准，然后实现图像的拼接。实验结果表明，该方法能够对重叠面积较小的图像序列实现快速拼接。

| Abstract: | In the field of infrared thermal wave nondestructive inspection, changes among infrared thermal wave serial images mainly include offset and rotation of small angles. Based on these features, the technology of phase correlation in FFT is used to determine the angle and offset within the possible rotation angle scope. Therefore, image registration is realized, and the images are mosaiced. The experiment result shows that serial images with little overlapping can be mosaiced efficiently. |
