柱面全景图像拼合及漫游算法研究

Research of image mosaic and navigation algorithm based on panoramic cylinder image

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.

The image-based modeling and rendering (IBMR) technique not only supplies the deficiency of the traditional geometry-based rendering techniques, but also creates more realistic images. This paper presents and realizes a new image algorithm, and then applies the Texture Mapping technology of OpenGL to glue a part of panoramic image as a texture image to the virtual visual space, which is (created) beforehand by using OpenGL. Finally, the navigation of a full view panoramic image of the virtual environment is got by changing the texture image.
