从地下室实验室看到的景观，美得令人屏息。这不是指那间一半位于地下的办公室里的小窗让人望见的景观，而是指计算机科学教授斯特吉尔斯·鲁迈利奥蒂斯在明尼苏达大学的华特图书馆里一边四处行走一边使用的智能手机屏幕上的厕面。在屏幕上，附近一条走廊的三维空间旁体地图已然成形。
The view from the basement laboratory is breathtaking.Not the one out the tiny windows of the half-underground office. It＇s on a smartphone that computer science Prof. Stergios Roumeliotis is using while walking around the University of Minnesota＇s Walter Library. On the screen, a three-dimensional map of a nearby hallway has taken shape. The map was made by holding the smartphone＇s camera while moving. The camera and the phone＇s motion sensor worked together to create a grid of data points that became a 3-D image.
