| 摘 要： | 图像配准常常是作为其他图像处理应用的前处理步骤使用的,往往用于图像的对准、目标识别与定位。介绍了在MATLAB系统中,如何应用MATLAB的IPT函数对图像进行配准的方法:首先用人机交互的方法在待配准图像与基准图像之间进行图像配准所必需的匹配控制点的选取,然后用这些匹配控制点来计算两图像的某种空间几何变换关系,最后利用这个空间几何变换关系对待配准图像进行几何变换,获得配准结果。实验表明,该方法实现容易,且非常有效。

| Abstract: | As a preprocessing step of image processing,image registration is applied to image comparison,object recognition and its orientation.A practical approach based on using the IPT functions in MATLAB is introduced in this paper.At first,the registering control point pairs between input image and base image are chosen by using of man-machine interactive interface.Then the space geometry transformation is calculated with the registering control point pairs.Finally,the input image is transformed and registered with the space geometry transformation.The easiness to be implemented and efficiency of the image registration approach described in this paper are proved in practice. |
