Abstract:
1. A transparent body detection system comprising: an image acquisition unit acquiring a vertical polarization image and a horizontal polarization image by acquiring an image of a first region, the image including a transparent body having characteristics in which a polarization direction of transmission light changes; a placing table on which the transparent body is to be placed; a polarization filter disposed opposite to the image acquisition unit across the placing table and at a position including a second region, an image of the second region including at least the transparent body in the first region and being acquired; an image processing apparatus detecting the transparent body based on distribution of vertical/lateral polarization degree of a vertical/lateral polarization degree image based on the vertical polarization image and the horizontal polarization image; and a light shielding member shielding indoor light from directly irradiating the transparent body when the transparent body is placed on the placing table under the indoor light.
