基于透视反求的基本体素三维重构关键技术研究*

研究了在一幅简单的透视图像中进行三维重构的方法。在对透视图像进行三维重构的过程中，从透视学的角度出发按照透视元素、基本体素、组合体素来逐步进行反求研究。在对透视元素点、线、面的透视反求中，从图形学的角度对其进行了基本的反求研究；对于有一定几何特征的基本体素BOX、圆球、圆柱、圆锥进行了详细的透视反求，给出了其相应的算法原理，并做了验证。

Research on 3D Reconstruction Based on Perspective

Present a new method which is used to reconstruct 3D models from a single perspective image. In the progress of reconstruction, from the perspective view, the perspective element, basic unit, and combined unit are researched. In the research of the perspective element (point, line, plane), from the graph point, the basic conclusion is given. The basic unit(BOX, sphere, column, taper) in detail is studied, and the correlative arithmetic is presented and validated.
