Development of a 3D endoscope system with higher function

研制了一种集环形光束装置和CCD摄像机于一体的三维内窥镜。通过对环形光束装置中使用的锥面反射镜的顶面进行评定，可以生成高质量的光学剖面图。利用亚像素处理成功地提取出了隐藏在像素之间的信息。结果表明，该测量系统的分辨率可达10μm。通过对环形光束的几何变化的关注，明确了三维内窥镜的轴向调整方法。在软件方面，实现了对缺陷检测的三维观察、展开图形和强度分布的检测。为了实现高精度的测量，三维内窥镜在环梁装置中引入了旋转机制。

A 3D endoscope incorporating a ring beam device and a CCD camera has been developed. By evaluating the top of the conical mirror utilized in the ring beam device, optical sectioned plane with high quality can be generated. It was successful to pick out the information hidden between pixels using a sub-pixel processing. As a result, the resolution of this measurement was attained to 10μm. It has been made clear an axial-adjustment method of the 3D endoscope by making attention with geometric variation of the ring beam. Regarding the soft ware, it was realized to inspect the flaw detection using a 3D view, a developed figure and an intensity distribution. To achieve high accuracy measurement, the 3D endoscope has introduced the rotating mechanics in the ring beam device.
