PROBLEM TO BE SOLVED: To provide an apparatus, a program and a method for processing three-dimensional data, wherein point group data obtained by a three-dimensional measurement instrument can be easily processed. SOLUTION: The three-dimensional data processing apparatus 1 includes a storage part 11, an arithmetic processing part 12, a display part 13, and an input part 14. The arithmetic processing part 12 includes: a distance image generation part 23 for generating a distance image 19 from point group data 5; a spherical surface image generation part 24 for generating a spherical surface image 18 from the point group data 5; and a coordinate calculation part 25 for calculating the three-dimensional coordinate value (x, y, z) of an optional measurement point of a measurement target 6 by using at least the distance image 19. A pixel of pixel coordinates (l, o) on the spherical surface image 18 and a pixel of pixel coordinates (m, n) on the distance image 19 are related to each other at the rate of one to one on a scanning position (i, j) of the three-dimensional measurement instrument 2.
