PROCESSING APPARATUS FOR THREE-DIMENSIONAL DATA, PROCESSING METHOD THEREFOR, AND PROCESSING PROGRAM THEREFOR

摘要

According to one embodiment, a three-dimensional data processing apparatus includes: an acquiring unit configured to acquire point group data measured by a three-dimensional measuring instrument that emits a beam for scanning from one position in a space in which a target object exists; a discriminating unit configured to discriminate a region unirradiated with the beam in the space on a basis of the point group data; a coordinate integrating unit configured to integrate, into one global coordinate system, respective local coordinate systems at a plurality of the positions at each of which the three-dimensional measuring instrument is placed; and an extracting unit configured to extract an overlapping region formed by integrating, into the global coordinate system, the unirradiated regions discriminated in the respective local coordinate systems.
