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.
