Classification: CPC G | IPC G

Claim 3:
4. The point cloud analysis device according to claim 2,
wherein the boundary point detector includes a divided region error estimator and a degree-of-division-boundary determiner,
the divided region error estimator estimates a region-of-interest error, a first error and a second error, the region-of-interest error being an error between a quadratic curve model obtained from the point cloud included in the region of interest and the point cloud included in the region of interest, the first error being an error between a quadratic curve model obtained from a point cloud included in the first region and the point cloud included in the first region, and the second error being an error between a quadratic curve model obtained from a point cloud included in the second region and the point cloud included in the second region, and
the degree-of-division-boundary determiner determines the degree of division boundary based on a model approximation error that is a difference between the region-of-interest error and an error based on the first error and the second error.
