An arrangement evaluation apparatus of a range sensor comprises an article arrangement unit which arranges an article model, a sensor arrangement unit which arranges a sensor model, a first plane group generation unit which generates a plurality of first planes including division lines obtained by dividing a virtual plane, a second plane group generation unit which generates a plurality of second planes by boundary surfaces of stripe pattern light projected from the projector model, an intersection line calculation unit which calculates intersection lines between the first planes and the second planes, and an intersection number calculation unit which counts the number of intersection points between the intersection lines and the surface of the article model.
