对立方体全景图、鱼眼图和球形全景图的生成算法进行研究,设计这三种全景图之间相互转换的算法,同时设计向全景图添加文字的算法。该系统实现立方体全景图、鱼眼图和球形全景图之间相互转化的功能,实现向全景图所构建的三维空间里的任意位置任意方向添加字幕的功能,字体、字号、颜色是可以根据系统选择的,可导入字幕文件,根据字幕文件格式自动向帧序列图像里添加文字。
A Kind of Adding Text System Based on Panorama
Studies the algorithms for the generation of cubic panorama, fisheye image and spherical panorama, and designs the conversion algorithms of the three kinds of panorama, moreover, designs the algorithm of adding text to panorama. The system provides a function that cubic panorama, converts fisheye image and spherical panorama each other, moreover, it achieves to add text to panorama in any direction and space which is built based on the panorama, the typeface, size and color of text can be selected by operation system. It can add text to the sequence of panorama frames by text file automatically.
