摘要
舰船在海上航行主要依赖GPS、雷达以及相应的综合导航系统进行导航,而使用视频设备进行导航的很少。运用OSGART增强现实组件把视频信息与基于地理信息的虚拟环境相结合,通过对摄像机地理空间的三维标定,构造出一个在地理空间、视觉空间和物理空间统一的合成环境平台。这个平台通过虚拟三维信息标注、视频信息与相应的虚拟海洋环境信息融合为航行导航手段。这种基于增强现实的导航方式与现在的GPS和雷达导航方式相比较,具有自然直观,空间立体感强及方便想象等特点,实验结果表明了系统的可行性。
For ship navigation,GPS,radar and marine integrated navigation system are mainly used,but vision systems can also be helpful,although they are not widely used.By using OSGART to combine vision information,through camera calibration in geographic space,with virtual marine environment based on GIS,a synthetic environment that integrates the real world and virtual world,unified in the spaces of geography,vision and physics is established.The video information and marine environment information together form an augmented 3D navigation environment,which gives more natural,intuitive telepresence than conventional methods.The feasibility of the method has been verified by experiments.
