The 3D coordinates of measured point is embodied in 2D image coordinate of the optical characteristic point via the visual measurement system. Based on the gray square weighted centroid localization algorithm
the paper presents bicubic interpolation gray square weighted centroid localization algorithm
increases the number of effective pixels around the optical characteristic point imaging center
and reduces noise error via the gray square weighted
improves the imaging center location accuracy of optical characteristic point
realizes the accurate location of the optical characteristic points. Results indicate application of the proposed algorithm to location
the standard tolerance along the direction of x is 0.0022 Pixel
the standard tolerance along the direction of y is 0.0023 Pixel
compared with the others
the standard tolerance is minimum and discrete to a lesser degree distancing ideal image point
that is
the proposed algorithm has higher location accuracy. The maximum tolerance along the direction of x is 0.008 Pixel
the one along the direction of y is 0.007 Pixel
compared with the other two algorithms
the maximum tolerance is minimum.Results indicate that the stability of the proposed algorithm is better. (2013) Trans Tech Publications
