1. An information processing device comprising:
a processor coupled to a memory storing instructions for the processor to function as:
an acquisition unit configured to acquire point cloud data outputted by a measurement device;
a down-sampling processing unit configured to generate processed point cloud data obtained by down-sampling the point cloud data; and
an association unit configured to match the processed point cloud data with voxel data which represents a position of an object with respect to each voxel that is a unit area and thereby associate a measurement point of the processed point cloud data with the each voxel,
wherein the down-sampling processing unit is configured to change a size of a subsequent down-sampling based on an associated measurement points number which is the number of the measurement points associated with the each voxel.
