Abstract
A 3D information calculation apparatus includes processing circuitry that may receive first and second images of different first and second wavelength bands, respectively, at a same time and angle of view based on a subject being imaged while structured light of the first wavelength band is projected on to subject, receive third and fourth images of the first and second wavelength bands, respectively, at a same time and angle of view based on the subject being imaged while the structured light is not projected on the subject, calculate a first difference image of the first wavelength band based on subtracting the first and third images, calculate a second difference image of the second wavelength band based on subtracting the second and fourth images, calculate an extraction image based on subtracting the first and second difference images, and calculate a distance to the subject based on the extraction image.
