Original Abstract Submitted

An object of the present invention is to provide a data compression device, a data compression method, and a program capable of thinning out a point group acquired by a 3D laser scanner without affecting the creation of a 3D model. A data compression device () according to the present invention is a data compression device which compresses three-dimensional (3D) point group data indicating 3D coordinates of points on a surface of an outdoor structure acquired using a 3D laser scanner while moving including: a point group deleting part (at least one of and ) which thins out the 3D point group data according to an arbitrary criterion and calculates scan lines deleted through the thinning-out of the 3D point group data; and an extraction processing part () which creates a 3D model from the thinned 3D point group data while skipping the deleted scan lines which are stored.
