Abstract:
A three-dimensional image capturing device, comprising:a plurality of laser devices that radiate pulse modulated laser beams for a distance measurement in order to detect distance information related to a topography of a measurement subject; an imaging device that accumulates a signal charge corresponding to a quantity of light received at said imaging device; and a laser radiating control processor that controls said plurality of laser devices to radiate said pulse modulated laser beams in a predetermined order, each laser device of said plurality of laser devices being disposed at predetermined intervals, each illuminating area of said laser beam radiated from said each laser beam overlapping each other at the distance of said measurement subject, said laser radiating control processor controlling said plurality of laser devices to radiate said laser beams in a predetermined order consecutively, so that consecutive said laser beams compose a single pulse beam for said distance measurement.
