说明：  基于图像的绘制技术不仅可以弥补传统基于几何绘制技术的不足,而且能给出更丰富的图像显示. 文中从实际应用出发,提出并实现了图像拼接新算法,并在此基础上,利用OpenGL的纹理映射技术,将全景 图像作为纹理图像映射到由OpenGL预先构造出的虚拟视点空间上,并实现了虚拟场景的全景漫游.
(Image-based rendering technology not only can make up for the traditional geometry-based rendering technology insufficient, and can give a richer image display. Text starting from the practical application of proposed and implemented a new algorithm for image mosaic, and on this basis, the use of OpenGL texture mapping technology, panoramic image as a texture image is mapped to the pre-constructed by the OpenGL virtual viewpoint space, and to achieve a virtual panoramic scene roaming.)
