本文提出了一种基于光条纹的三维重建方法，用于从真实的物体重建三维模型。建议的系统包括一个光平面投影仪，相机和立方体框架与LED连接。与其他光条纹系统一样，通过将光平面投影到帧内的对象上来解决对应问题。然而，我们只使用交比和消失点来建立物体的世界坐标，而不需要相机的内外参数和光源的位置。因此，所提出的系统不校准相机和光源。此外，计算的3D点数据不需要配准过程，因为数据是基于统一的世界坐标直接测量的。实验结果证明了测量的准确性和结果的一致性，而无需了解相机和光源参数。
This paper presents a new approach based on light striping for reconstructing a 3D model from a real object. The proposed system consists of a light plane projector, camera and cube frame with LEDs attached. As in other light striping systems, the correspondence problem is solved by projecting light plane onto an object inside a frame. However, we use only cross-ratios and vanishing points to set up the world coordinates of the object, while the intrinsic and extrinsic parameters of the camera and the position of light source are not required. As such, the proposed system does not calibrate the camera and the light source. Furthermore, the computed 3D point data does not require by registration process because the data is directly measured based on unified world coordinates. Experimental results proved the accuracy of the measurements and consistency of the outcomes without any knowledge of the camera and light source parameters.
