Paper Abstract

The keys to realize the on-line measurement of revolving body's profile based on the digital image measuring method are the calculation accuracy and speed of the sub-pixel edge detection algorithm. In this paper, several kinds of sub-pixel edge detection algorithms are studied. Based on this study, a new sub-pixel edge detection algorithm named mixed algorithm is developed. The experimental results confirm that the new algorithm is stable and reliable. It can not only advance the calculating speed, but also extend the accuracy of position to better than 0.01pixels.
