A Research on 3D Reconstruction Based on Structured Light

三维重建是计算机视觉领域中的研究热点,为了实现纹理较少的物体的三维重建,给出了一种通过在物体表面投射结构光的双目立体视觉系统设计与实现:首先,单个摄像机通过机器臂水平移动一定距离形成虚拟的双目立体视觉系统,简化了标定过程,然后投射规则结构光增加物体表面纹理,提高左右图像立体匹配效率,最后,结合系统标定获得的相机参数利用视差原理得到三维空间坐标。实验结果表明,这种系统标定简单,可以完成纹理较少的物体三维重建。

3D reconstruction plays a role in the field of computer vision. A binocular stereo vision system is designed to reconstruct the less texture of 3D object by projecting structured light on the object surface. In the process of the reconstruction, firstly a robot arm moves a single camera horizontally to form a virtual binocular stereo vision system, which simplifies the calibration process. Then the regular structure light projects on the object surface to increase the texture and improve the efficiency of stereo matching. Finally the three dimensional coordinates are obtained by the data of calibration and parallax principle. The experiment of results show that this system calibrate simply and can reconstruct the less texture of 3D object.
