Title:
POINT GROUP PROCESSING DEVICE, POINT GROUP PROCESSING METHOD, AND POINT GROUP PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/127528
Kind Code:
A1
Abstract:
This point group processing device includes: an input unit that receives three-dimensional point groups on the surface of an object; a clustering unit that performs clustering on the three-dimensional point groups and derives clusters that are three-dimensional point groups that represent a building; and a repetition determining unit that causes the clustering by the clustering unit to be repeated until a predetermined repeat ending condition is satisfied. The clustering unit changes the clustering size so as to be smaller at each repetition and performs clustering on three-dimensional point groups represented by the clusters obtained in the previous clustering.
