Abstract:
A method for measuring the distance of an object is provided that includes irradiating a plurality of light beams having predetermined wavelengths and then in a first round, picking up an image under irradiation of the plurality of light beams and in another round picking up the image without irradiation using a camera. The difference of the image between the first and other round is fed to an observation region part and to an irradiation angle computing part and then the distance to the object is computed.
