RANGE FINDER AND METHOD

A linearly polarized light projector system projects linearly polarized light onto a subject. While polarizing filters are used for removing light specular-reflected on the subject, a reflected image after removal of the specular-reflected light is captured by image input systems different in view point. Even in the case where the subject is glossy, the number of points for measuring the shape of the subject is increased and range images improved in measurement accuracy can be acquired collectively.
