Abstract
A distance measuring device with a patterned-infrared-light irradiator, a near-infrared-light camera, a visible-light camera, a first imaging section having spectral response characteristics in a wavelength band of visible light and a predetermined wavelength band of invisible light a second imaging section having spectral response characteristics in the wavelength band of the visible light, an invisible-light projector for projecting the invisible light of the predetermined wavelength band in an angle-of-view range of the first imaging section; an invisible-light-aided distance computing section adapted to conduct image processing of an image formed by and output from the first imaging section, a stereo distance computing section adapted to conduct stereo image processing of both the image formed by and output from the first imaging section, and an image formed by and output from the second imaging section, and a distance computation controller adapted to control computation conditions used for the invisible-light-aided distance computing section.
