Method for construction of three-dimensional digital model of physical surface i.e. casing, of statue, involves applying transformation between rotating component and translation component to one of mottled points

摘要

The method involves calculating a relative rotating component of a scanner between two positions at acquisition instants of a pair of stereoscopic images associated with mottled points from data provided by an inertial unit of the scanner. Coordinates of a characteristic point are determined from the mottled points. A translation component between the mottled points is determined from the coordinates of the characteristic point. Transformation between the rotating component and the translation component is applied to the other mottled point during recycling phase of the mottled points. Independent claims are also included for the following: (1) a compute program comprising a set of instructions implementing a method for construction of a three-dimensional digital model of a physical surface (2) a three-dimensional digitization system comprising a CPU on which the computer program is implemented.
