图像拼接的预处理算法研究

Research on Pretreatment Algorithm in Image Mosaic

在基于图像的虚拟现实中,为了加快相邻图像的拼接速度,提出了对图像进行灰度化,然后将灰度图投影,进行粗略匹配的预处理算法。实例表明,该算法可以有效地实现图像预定位,缩小图像拼接时的搜索范围,提高拼接速度。

A pretreatment algorithm of image-based virtual reality is suggested to speed up the rate of image stitching in this paper. The algorithm first grays the image, the grayscale image is projected and then pretreatment algorithm is used to match the image roughly. It is proved via the examples that the algorithm can effectually pre-orientate the image, reduce the range of search in the image stitching, and speed up the rate of image stitching.
