Abstract
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 three-dimensional (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 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 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.
