摘　　要：图像拼接在天文图像处理、日常照片扩展、大型图像的获得等方面应用极其广泛,是地理、人文、科技发展的重要标志。本文采用基于特征的图像拼接算法,利用Canny算子进行边缘检测提取数字图像特征,通过图像预处理(去噪,边缘提取,直方图处理等)、图像配准、图像重构融合等操作,在Matlab平台下实现两幅大小一样、光照条件一致的灰度图像的拼接。Image mosaic is widely used in astronomical image processing,daily photo expansion and large image acquisition.It is an important symbol of the development of geography,humanities and science&technology.In this paper,based on digital image,Canny algorithm is used for edge detection.Through image preprocessing(denoising,edge extraction,histogram processing),image registration,transformation model establishing,unified coordinate transformation,reconstruction and fusion,the two gray-scale images are stitched in Matlab platform.

关 键 词：边缘检测 CANNY算子 灰度图像 图像拼接
