Abstract

A spatial-information generation apparatus according to an embodiment of the present invention includes a reference-plane acquirer, a simplification-section setter, and a shape simplifier. The reference-plane acquirer acquires, on the basis of a first spatial object related to a first space, first attribute information indicating attributes of the first spatial object, and first relation information indicating a relation between the first spatial object and objects of other constituent elements of the building, a reference plane object related to a plane of a part of the first space from the first spatial object and generates a shape of the reference plane object. The simplification-section setter sets a simplification section, which is a target to be simplified, in the shape of the reference plane object. The shape simplifier simplifies the shape of the reference plane object in the simplification section to thereby generate the reference plane object in the simplified shape.

3 . The spatial-information generation apparatus according to claim 2 , wherein, when the simplification section set by the first simplification section setting is simplified, the shape simplifier confirms whether an overlapping portion of a simplified reference plane object in the first space and a simplified reference plane object in the second space is present and, when the overlapping portion is present, further simplifies a shape of the overlapping portion to eliminate the overlapping portion.

4 . The spatial-information generation apparatus according to claim 1 , wherein, when simplifying the simplification section set by the first simplification section setting, the shape simplifier traces the simplification section in a direction decided in advance, recognizes a convex section or a concave section present in the simplification section and linearizes the convex section or the concave section to thereby simplify the simplification section.

The spatial-information generation apparatus according to claim 1 , further comprising a direction-axis acquirer that generates direction axes including orthogonal two axes on the basis of shapes related to third constituent elements, which are one kind of the constituent elements of the building, in the shape of the reference plane object and directions of the third constituent elements, wherein
when there is a third straight line, which is not parallel to both of the direction axes, connected to one ends of first and second straight lines parallel to either one of the direction axes in the shape of the reference plane object, the shape simplifier generates a first intersection and a second intersection, which are intersections of a straight line passing a midpoint of the third straight line and perpendicular to the first and second straight lines and extended lines of the respective first and second straight lines, connects another end of the first straight line and the first intersection, connects another end of the second straight line and the second intersection, and connects the first intersection and the second intersection, and deletes the third straight line from the first straight line to thereby change the shape of the reference plane object to a shape parallel to the direction axes.

7 . The spatial-information generation apparatus according to claim 6 , wherein the spatial-structure machiner calculates a ratio of a longitudinal width or a lateral width of a first divided piece among the plurality of divided pieces to a smallest longitudinal width or lateral width in the plurality of divided pieces and divides the longitudinal width or the lateral width of the first divided piece by the ratio.

8 . The spatial-information generation apparatus according to claim 6 , wherein the spatial-structure machiner divides a longitudinal width or a lateral width of the plurality of divided pieces on the basis of a designated unit area.
