【摘要】 增强现实是把计算机生成的虚拟图像或其它信息叠加到用户所看到的真实世界中的一种技术,是虚拟现实领域的一个难点热点。ARToolKit为增强现实技术的应用提供了一种方便快捷的开发工具,但其不足之处在于它是基于计算机视觉的注册方式,不适合户外增强现实系统的开发,需要做进一步的改进。论文利用ARToolKit在室内实现了管网三维可视化的增强显示,取得了满意的效果;根据户外的实际,提出了以全球定位系统载波相位差分(GPSRTK)和惯性导航系统(INS)相结合进行精确定位、以电子罗盘和倾角计相结合测定视线方向的混合注册方法;对利用ARToolKit建立户外地下管网增强现实系统的框架及功能作了进一步的探讨。更多还原

【Abstract】 Augmented Reality(AR) is a technology that overlays virtual image and information generated by computer on real world and it is a new area in the research of virtual reality.ARToolKit provides a convenient and quick tool to develop AR application,but its registration methods is based on vision and is not suitable for outdoor AR application.So,ARToolKit should be improved.This paper performes augmented visualization of 3D pipeline indoor with ARToolKit,and puts forward a hybrid registration based on RTK GPS,INS and angle trackers in outdoor AR system.This paper also describes the frame and application of outdoor 3D pipeline augmented reality system.更多还原
