THREE-DIMENSIONAL MODEL GENERATING DEVICE, METHOD OF DETERMINING STRUCTURAL MEMBER, AND PROGRAM

摘要

In order to automatically determine a structural member that is included in a structure and has flat surfaces, an input unit is configured to input three-dimensional point group data of the structure, a flat surface extraction unit is configured to extract the flat surfaces of the structure based on the three-dimensional point group data, a grouping unit is configured to group the flat surfaces into flat surface groups based on an angle of each of the flat surfaces with respect to a reference direction and a distance between the flat surfaces, a connection relationship extraction unit is configured to extract a connection relationship between the grouped flat surface groups, and a determination unit is configured to determine the structural member that the structure is constructed from based on the extracted connection relationship.
