用未定标相机构造三维模型

Creating 3D Models with Uncalibrated Cameras

我们提出了一种新的基于图象的造型方法。与传统的需要精确定标的体积建模方法不同,这种方法只需要弱定标。这种方法有三步,首先是灭点进行摄像机定标,然后用空间雕刻算法得到三维模型,最后用视点相关的合成方法改善结果。

In this paper, we describe a new image based modeling method. Unlike traditional volumetric methods which need precise camera calibration, this method just uses weak calibration. The method takes three steps: first, use vanishing points to calibration; second, use space carving algorithm to get 3D model; last, use view dependent synthesis method to improve the result.
