“…In the literature, refinement usually depends on application of the well-known iterative closest point (ICP) algorithm [6,14,42]. ICP starts from an initial transformation estimate, and uses this to map points from one scan (the ''moving'' scan) onto the second scan (the ''fixed'' scan) in order to establish temporary correspondences between points in the two scans.…”

“…Being particularly legible and effective, this method or its improved variants [2][3][4][5][6][7] are widely used in localization problems. Based on a similar idea, Menq et al [8,9] developed an optimal match scheme that aligns the measured data with the design surface for the precision measurement of the surface profile. To improve the computational efficiency of the transformation matrix, a modified algorithm is then proposed based on the technique of pseudoinverse.…”

“…Normally, it is treated as solving a non-linear optimization problem. Various optimization methods such as the Newton method and NewtonRaphson method are usually used to solve it [8,10,18,19]. When a good initial value is available, the result of this iterative approach is of high accuracy.…”

“…In industrial automation, a workpiece is typically localized by finding the optimal registration of some measured points onto a given CAD model [19], [31], [33]. The general scheme iteratively improves on a transformation in order to minimize some least-squares error function and also on the registration of the measured data points.…”
