Abstract
A range image obtaining system for a track includes a laser slit light source disposed within a plane perpendicular to a tread of a rail and emits laser slit light within the plane; a two-dimensional image imaging device which is disposed to have an angle with respect to the plane perpendicular to the tread of the rail and obtains a light sectioning image generated from the laser slit light; and an image signal processing device for generating a range image based on a distance from the two-dimensional image imaging device based on the light sectioning image.
