PROBLEM TO BE SOLVED: To facilitate grasping of finished shapes newly completed or scaffolding materials having disappeared within a prescribed period.SOLUTION: A structure state grasping support device 10 is equipped with first conversion means that converts a structure point group model 30a representing a structure 90 in a group of points into a first structure voxel model 30a representing the structure 90 in voxels, second conversion means that converts a structure voxel model 30b representing the structure 90 at a point of time different from the case of the structure point group model 30a into a structure voxel model 30b representing the structure 90 in voxels, and extracting means that extracts voxels 38 that exist in the structure voxel model 30b but not in the structure voxel model 30a by taking the difference between the structure voxel models 30a and 30b.SELECTED DRAWING: Figure 9 |
