Abstract
The paper presents a new method that computer vision technology based on CCD is applied in testing the inner wall of tube. The existing edge detection method is analyzed. The precise extraction algorithm of cracking edge location based on spatial moment is derived in detail. By using software algorithms, the precise edge location can reach sub-pixel level; the crack length of artillery bore can be measured accurately.
