摘　　要：简述了全景图像的成像原理。用小波变换方法对图像进行处理,小波分解后,保留局部图像的所有信息,即局部图像的低频成份和三个高频成份,而对其他它区域进行特殊处理,然后再对这些信息进行编码。该方法在处理全景图方面简便易行,在保留局部图像的所有信息的情况下,提高了压缩比。In this paper, the principle of image formation of the panoramic picture has been introduced. Image processing is based on wavelet transforming method. After wavelet decomposition, all the messages of local image are preserved, i.e. the low-frequency component and three high-frequency components of local image. And for other areas the special processing is made. Then these information is encoded. The method is simple and easy in dealing with the panorama. In the case of preserving all the message of local image, it improves the compression ratio.
