摘要

介绍一种新型的基于圆锥反射镜的内壁图像获取方法

用以检测4

0 mm孔径的内壁图像。在小孔内引入圆锥反射镜作为反射装置;采用工业CCD相机作为图像采集设备

用以获取反射镜上的反射图像;利用数字图像处理技术将圆环形图像变换为矩形展开图。方案简单新颖

具有可行性和实用价值

且获得图像分辨率高

由理论计算可达10μm级别。

Abstract

Introduce a new method for image acquisition of inside wall of 4

10 mm diameter holes. A cone reflector is placed inside the hole for the reflection and a CCD to acquire the reflection image. Besides

digital image processing technique is used in the image conversion. The method is innovative and easy to realize. It has high feasibility and practical value

besides

the image resolution is up to 10 μm level by theoretical calculation.
