VERFAHREN UND SYSTEM ZUR AUSRICHTUNG DREIDIMENSIONALER OBERFLÄCHEN

摘要

The invention relates to a method for aligning a three-dimensional surface representing a real object and a three-dimensional reference surface the method comprising the steps of providing a cloud of points representing the reference surface; obtaining a cloud of points representing the real surface; scaling the cloud of points of the reference surface for obtaining a sub-cloud of points; scaling the cloud of points of the real surface for obtaining a sub-cloud of points; determining the normal vector of each point of the obtained sub-cloud of points of the real surface; obtaining, among the points of the sub-cloud of points of the real surface, control points according to the determined normal vector of said points; obtaining, from the points of the sub-cloud of points of the reference surface, the points corresponding to the control points of the real surface; obtaining the motion that minimizes the distances between the control points of the real surface and the obtained correspondence points.
