Title: IMAGING UNIT AND METHOD FOR INSTALLING THE SAME
Abstract:
An imaging unit includes a light source, an imaging element to receive a light having entered an outer surface of the transparent plate-like member from a predetermined imaging area and transmitted through the transparent plate-like member and a light from the light source reflected by an attached matter on the outer surface, to capture an image of the predetermined imaging area and that of the attached matter, a mirror module fixed on the internal surface of the transparent plate-like member to fixedly support a reflective mirror to reflect the light from the light source, an imaging module to fixedly support the light source and the imaging element, fixed relative to the internal surface of the transparent plate-like member so that the imaging element captures an image in a certain direction, and a positioning mechanism to determine relative positions of the mirror module and the imaging module.
