<P>PROBLEM TO BE SOLVED: To provide a guide line imaging device for generating image data with no overexposure and an unmanned carrier equipped with the guide line imaging device. <P>SOLUTION: A guide line imaging device configured as a guide line imaging device installed in an unmanned carrier which travels along a guide line laid on a road surface includes: imaging means for optically imaging an area including the guide line on an imaging surface to generate the image data of the area; one or more illumination means for illuminating the area to be imaged with the rays of light emitted from an emission surface; a first polarization filter 6 arranged on the imaging surface; and a second polarization filter 7 arranged on the emission surface. The guide line imaging device is characterized such that the vibrating direction of the rays of light L5 capable of transmitting through the first polarization filter 6 is made different from the vibrating direction of the rays of light L2(L3) capable of transmitting through the second polarization filter 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
