Object modelling by registration of multiple range images
Yang Chen,Gerard Medioni +1 more
TL;DR: A new approach is proposed which works on range data directly and registers successive views with enough overlapping area to get an accurate transformation between views and is performed by minimizing a functional which does not require point-to-point matches.
