摘要
为了克服全息和双目表面重建的某些弱点,利用光栅投影生成二维图像之几何特性,建立投影二维平面图像和三维空间图像的对应关系,并由此确定三维物体表面点的空间坐标,最后利用计算机图形学和虚拟现实的理论与技术绘制出三维物体表面。
A new method for 3D object reconstruction is proposed using theories and techniques of geometric projection,computer graphics and virtual reality. Firstly, 2D images are generated using raster projection. Then, the relations between the 2D images and the 3D images are built up using the properties of raster projections. The coordinates of the 3D surface points are determined with respect to the relations. Finally, the surfaces of 3D objects are constructed using the theories and techniques of computer graphics and virtual reality. The method of 3D object reconstruction from raster projection has the advantages of simple and easy implementation,and low cost equipments.
