| Abstract: | To satisfy the stringent requirement of measuring accuracy of fast charge coupled device(CCD) measurement system, a novel method is proposed based on improved algorithm Canny and Zernike moments of the subpixel image edge detection methods. The algorithm to using improved Canny operators to achieve coarse edge point positioning firstly, and the pixel coordinates of edge points and gradient direction are identified at the sane time, then according to the edge point is relocated with sub-pixel accuracy by mea... |
