Claim 4:
5. The point cloud analysis device according to claim 1,
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 first error and a second error, the first error being an error between a quadratic curve model obtained from a point cloud included in the first region and a point cloud included in the second region, and a second error being an error between a quadratic curve model obtained from the point cloud included in the second region and the point cloud included in the first region, and
the degree-of-division-boundary determiner determines the degree of division boundary based on a model approximation error that is the greater of the first error and the second error.
