全方位图像展开成全景和透视图的实现方法

Generation of Panoramic and Perspective Views from Omnidirectional Images

全方位视觉系统生成的全方位图像能获得水平方向3600环境信息,非常适合于某些有大视场需求的应用。该文介绍了全方位图像的特点、生成原理及其展开成全景图及透视图的具体实现方法。同时也介绍了以DirectShow为工具,全方位视频的展开实现方法。最后通过实验证明了全景图及透视图生成方法的有效性。

Omnidirecitonal images generated from omnidirecitonal vision system can obtain 360-degree horizontal view, so it＇s suitable for applications which need large field of view. This paper introduces the imaging process of the omnidirectional image, the generation of panorama and perspective images from omnidirecitonal images. The unwarping process of omnidirectional video based on DirectShow technology is also included. An experiment is presented to prove the method at last.
