三维虚拟仪器馆快速构建方法研究
|
摘要
针对当前虚拟仪器馆三维数字化建设成本高、周期长等问题,提出了一种基于普通相机的三维虚拟仪器馆快速构建方法。首先按照摄影测量三维立体视觉要求,采集具有高重叠度的大量影像;然后以多视影像密集匹配构建仪器馆三维模型,并在此基础上实现三维虚拟仪器馆的在线发布;最后以武汉大学摄影测量仪器馆为例,采用该方法搭建了网上三维虚拟仪器馆,服务于新生的专业认知教学、虚拟实验教学和摄影测量与遥感科普,具有推广应用价值。
In view of the current situation that virtual instrument museum of 3D digital construction has high cost, long construction period and so on, we put forward a rapid construction method of 3D virtual instrument museum based on general camera. Firstly, we collected a large amount of images with high degree of overlap according to photogrammetry 3D stereovision requirements. And then, we constructed 3D model of instrument museum based on multi-view image dense matching, and realized online publication of 3D virtual instrument museum. Finally, taking the photogrammetric instrument museum of Wuhan University for example, we used this method to construct an online 3D virtual instrument museum, which served the freshmen's professional cognitive teaching, the virtual experiment teaching, the popularization of photogrammetry and remote sensing, and possessed of popularization and application value.
