基于彩色结构光的实时三维重建

REAL-TIME 3D RECONSTRUCTION BASED ON COLOUR-CODED STRUCTURED LIGHT

提出一种新颖的基于彩色结构光的实时三维重建方法RRCS(Real-time 3D Reconstruction based on Color-coded Structured light),利用投影在物体表面的彩色结构光的彩色信息,快速准确地还原相位,计算出物体的高度,最终重建物体的三维模型。针对RRCS的特殊性,设计了基于拓扑排序的解相位算法,以及针对点线的快速三角网化算法。实验结果表明,RRCS对设备的要求低,效果较好,具备基本的实时性能。

The paper proposed a novel real-time 3D reconstruction system based on colour-coded structured light （RRCS）. It retrieves phase quickly and correctly by using the colourful information of colour-coded structure light projected on the surface of object, and then calculates the height of the object in order to finally reconstruct the three-dimension model. In light of the speciality of RRSC, in the paper a phase shifting algorithm based on topological sorting and an algorithm of quick triangulated net building aiming at points and lines are also designed. Experiments indicate that RRCS has low requirement in hardware with good effect,it possesses basic real-time ability.
