Automatic 3D model acquisition using surface scanners


The models produced by means of the available 3D-surface scanning technologies are considered accurate enough for most applications. Unfortunately, the acquisition of complex objects is still a demanding and human-intensive process that cannot be performed by non-specialists.

Among the open problems, one of the most difficult to grasp is planning the acquisition session, i.e. choosing a set of scanner positions to view the whole surface of the object.

Another human-intensive phase is surface registration, and a painful one if large objects are being imaged.

This research addresses both issues of registration of range maps and sensor planning, in the context of 3D model acquisition.
