PROBLEM TO BE SOLVED: To provide a topography information acquisition device that is capable of attaining an effect allowing for an accurate and efficient preparation of a three-dimensional map for a deficient amount unacquirable by a UGV.SOLUTION: A topography information acquisition device 1 comprises: an area identification section 100 that refers to a preliminary prepared three-dimensional map as to a part of topography in a predetermined area, and identifies, of the predetermined area, a complete area having the three-dimensional map completed, and an incomplete area having the three-dimensional map non-prepared; a topography gradient estimation section 101 that estimates a topography gradient in the incomplete area on the basis of the three-dimensional map; and a topography data acquisition section 11 that optimizes a topography data acquisition condition on the basis of the incomplete area and the estimated topography gradient in the incomplete area, and acquires topography data in the incomplete area.
