| Abstract: | Unlike traditional perspective projection, fisheye projection can construct a virtual environment with special effects such as wide view and global view. This paper, based on the concepts of two kinds of fisheye projection and latitude-longitude projection image, implements the algorithm to produce angular fisheye projection from latitude-longitude projection image. The algorithm has a viewing capability of three-degree-of freedom in terms of camera rotating and continuous zooming. Finally, our experimental results show the features of virtual environment based on fisheye projection. |
