摘要

我们提出了一种用于部署大规模投影式地板显示系统的校准方法。在我们的系统中,在体育馆等大型室内空间的天花板上安装了多台投影仪,以实现地板上的大投影面积。投影结果受到透视畸变和透镜畸变的双重影响。在本文中,我们使用投影机-摄像机系统,在每个投影机上安装一个摄像机,用“直线必须是直的”方法来校准我们的投影系统。与传统方法不同的是,该方法不使用任何校准板,也不要求投影与摄像机视场之间的重叠。

A Calibration Method for Large-Scale Projection Based Floor Display System
We propose a calibration method for deploying a large-scale projection-based floor display system. In our system, multiple projectors are installed on the ceiling of a large indoor space like a gymnasium to achieve a large projection area on the floor. The projection results suffer from both perspective distortion and lens distortion. In this paper, we use projector-camera systems, in which a camera is mounted on each projector, with the “straight lines have to be straight” methodology, to calibrate our projection system. Different from conventional approaches, our method does not use any calibration board and makes no requirement on the overlapping among the projections and the cameras' fields of view.
