文章摘要
提出一种全景视频增强现实系统的建设方案。将全景视频采集装置放置在真实世界中采集视频,然后通过计算机处理生成全景视频并显示出来,使观光者通过佩戴显示设备,在其他地方观看向全景视频中添加了虚拟信息的场景。解决了系统中全景视频拼接中算法复杂度高且拼接后的视频存在拼接裂缝和"GHOST"现象,以及三维注册易受环境与目标跟踪检测算法耗时严重影响的技术难点。通过对ARToolKit二次开发,将3DMax生成的虚拟信息叠加到Ladybug拍摄后拼接的兰州市金城关全景视频中进行仿真实验。仿真结果表明,全景视频拼接方法在实时性方面表现优异,有效地抑制了拼接裂缝和“GHOST”现象,增强现实三维注册方法对于全景视频的局部增强效果表现优异。
Abstract
This paper proposes a construction scheme of panoramic video augmented reality system. The panoramic video collection device is placed in the real world to capture video, and then processed through the computer to generate panoramic video and display, so that visitors wear the display device, in other places to watch the panoramic video to add a virtual information scene. The scheme solves the problem of high complexity of the algorithm in the panoramic video splicing system and the existence of stitching cracks and “GHOST” phenomenon. The scheme also solves the technical difficulty that the 3D registration is susceptible to environment and target tracking detection algorithm is time-consuming. Through the secondary development of ARToolKit, the virtual information generated by 3DMax is superimposed on the panoramic video of Lanzhou Jincheng Pass, which is shot and spliced by Ladybug, to carry out the simulation experiment. The simulation results show that the panoramic video stitching method is excellent in real-time performance, effectively restraining the existing stitching cracks and "GHOST" phenomenon, and the enhanced reality 3D registration method is superior to the local enhancement effect of panoramic video.
