Associating 6 DoF sensor data to 3D scan view registration

Abstract

To make 3D scanning an attractive tool for incidental or inexperienced users, the process of scan view registration should be avoided or significantly simplified. If a 6 DoF sensor is attached to the object to be scanned, additional data about each of the 3D views can be supplied to the registration software as to provide initial relative placements of pair of views, thus making automatic matching feasible. This releases the user from the tedious manual registration process. A method to apply a 6 DoF device to 3D scanning is in development. To calibrate the sensor to the scanner, the equation of similarity matrices needs to be solved. We verified numerically that this leads to ambiguities if only one sensor-to-scanner association is measured. A method based on a geometric treatment is proposed to achieve an unambiguous association between the two devices. Initial numerical results are presented.
