基于多视图的三维模型采集系统的研制

研制了一种基于多视图的三维模型采集系统,该系统用三维扫描和立体视觉技术,利用一台相机,结合必要的机械结构即可完成三维模型的采集工作。实验研究结果表明:该系统在圆周方向的测量平均偏差Rr=0.94,在长度方向的测量平均偏差Rl=0.87,符合一些3D打印逆向工程领域的精度要求,与传统的三维模型采集系统相比较,该系统成本较低,可以完成较高精度的三维模型采集工作,为深入研究三维模型采集系统奠定了良好的基础。

Research on 3D Model Acquisition SystemBased on Multiple View

A new 3D model acquisition system is designed based on multiple view used the technology of 3D scanner and stereo vision, 3D model collection can be conducted using one camera combined with basic mechanical system. 3D model acquisition system was used for calibration experiments and the experimental results shown that the mean deviation in circumferential direction Rr=0.94 and in line direction Rl=0.87 which can meet the accuracy requirement in 3D printing reverse engineering areas. 3D model acquisition system based on multiple view can perform high accurate collecting task at low-cost compared to traditional system. This achievement was the foundation work to the depth study of 3D model acquisition system.
