描述了一种用于在诸如足球场的超大规模空间中记录多个视频的系统。它克服了在大范围空间中记录同步多个视频和校准多个摄像头的困难的问题。该系统可以记录完全同步的多个视频，对同一时刻捕获的每一帧具有相同的时间戳。大尺度空间中的摄像机标定需要建立一个精确的3D世界坐标系，并定义多个地标。拟议的系统通过将校准板与3D激光测量仪器相结合来实现这一点。还描述了一种从多个视频合成新视角的方法，以及一些实验结果。本文所研究的技术是实现大规模空间虚拟现实的基础。
A system for recording multiple videos in a very large-scale space, such as a soccer stadium, is described. It overcomes the problems of difficulty in recording synchronized multiple videos and in calibrating multiple cameras in a large-scale space. The system can record completely synchronized multiple videos with an identical timestamp for every frame captured at the same instant. Camera calibration in a large-scale space requires setting up an accurate coordinate system of the 3D world and defining many landmarks. The proposed system does this by combining a calibration board with a 3D laser-surveying instrument. A method for synthesizing a novel view from the multiple videos is also described, along with some experimental results. The technique deserbed in this paper is essential to realize a virtualized reality in a large-scale space.
