Claim 0:
1. A point cloud analysis device comprising:
a region-of-interest determiner configured to set a plurality of regions of interest obtained by window-searching a wire model including a quadratic curve model representing a cable obtained from a point cloud consisting of three-dimensional points on an object, the region of interest being divided into a first region and a second region; and
a boundary point detector configured to:
compare information on the first region with information on the second region based on a point cloud included in the region of interest and the quadratic curve model for each of the plurality of regions of interest,
determine, based at least on a distance between the wire model around the region of interest and the region of interest using a predetermined machine learning, a degree of division boundary representing a degree to which a division position between the first region and the second region of each of the plurality of regions of interest is a branch point of the cable, and
detect a division boundary point that is a branch point of a cable represented by the wire model based on the degree of division boundary determined for each of the plurality of regions of interest.
