Outline of Final Research Achievements

The purpose of this research is to develop advanced and fully-automated software for object recognition and modeling from massive laser scanned point clouds captured from large-scale equipment with current status to automatically construct “as-built equipment model” where each object in the equipment is semantically annotated. The software also aims for updating the as-built model continuously over time with minimum effort of additional laser scanning operation over long term, and for proposing a set of common and invariant primitive point clouds processing algorithms to support the recognition and modeling chemical plants, large-buildings, electric power plants etc.
