| 摘 要： | 提出面向应急系统的一种路途全景图像与GE相结合的虚拟环境构建方法。以汽车为移动平台,利用摄像机和GPS设备采集数据,通过视频拼接生成路途全景图像,根据GPS位置信息生成三维景物立面,再以路途全景图像为纹理对景物立面进行贴图,最后把生成的虚拟模型导入Google Earth。实验证明该方法简单实用,对硬件以及网络环境要求低,且具有较强的扩展能力,能够在一定程度上提高指挥员应急指挥和处置能力。

| Abstract: | An emergency system oriented virtual environment reconstruction method based on route panorama and Google Earth is proposed.First video and GPS data are captured on a moving platform.The route panorama is generated from the video.The 3D scenes facade is reconstructed according to GPS information and is rendered with route panorama as the texture.The virtual environment is completed by loading the model to Google Earth.The experiments show that the method is simple and practical.The method has low requiremen... |
