用简单旋转装置实现三维相机多视角数据采集

提出一种用简单旋转装置实现单视角三维相机对物体进行多视角表面数据采集的方法.论述了基于这一方法的多视角三维相机的构造,旋转装置参数的标定,以及不同视角采集的物体表面三维数据直接通过相应的空间坐标变换关系对齐复位的方法;推导了关于旋转角度的空间坐标变换函数,分析了由旋转装置引入的多视角数据对齐复位的误差,最后给出了实例并进行了讨论.本方法构成的多视角三维相机将具有系统简单,采集过程无需附加操作和特殊要求,可确定的对齐复位精度以及全自动化的快速采集复位过程等特点.

An Approach for Multiple-view Data Capture by a Single-view 3D Camera Using a Simple Revolve Device

An approach is proposed for multiple-view 3D capturing by a single-view 3D camera using a simple revolve device. In this article we discuss the structure of a multiple-view 3D camera based on our method, the configure calibration for the revolve device and the alignment of the object surface 3D data captured from different views directly through space coordinate transformation. We have also demonstrated the space coordinate transformation function with regards to the revolve angle. The alignment error caused by the revolve device is analyzed, and an example is given and discussed. The multiple-view 3D camera based on our method will have many advantages: simple system, no additional operation and special requirement when capturing, computable alignment precision, automatic and rapid capturing and alignment processing.
