In the case of shoe midsoles produced through a foam mold process, shape differences occur even between the same parts owing to the characteristics of the production method. Thus, the automation of shoe manufacturing is hindered. To solve this problem and register, the non-rigid registration that allows stretching can be used. To implement the matching algorithm, approximate matching using the second moment of inertia and precise matching using MBA(multi-level B-spline approximation) are used. In particular, we propose the method of repeatedly performing low-resolution MBA to minimize the impact of noise. Finally, the registration error and required time are measured to determine whether the algorithm is suitable for use in real-time processes.
