Document Type and Number:
WIPO Patent Application WO/2019/175918
Kind Code:
A1
Abstract:
According to the present invention, a point data acquisition part (21) acquires a set of point data that indicate reflection points and have been obtained by a light sensor (41) that receives reflected light that is the result of radiated light beams being reflected at the reflection points. The point data are combinations of primary point data that indicates a primary reflection point that is a reflection point for a particular beam of light and secondary point data that indicates a secondary reflection point that is a reflection point for the particular beam of light and from which the intensity of reflected light is lower than from the primary reflection point. A fog specification part (22) specifies the thickness of fog on the basis of the distribution of the distances between the primary reflection points and the secondary reflection points of the point data included in the acquired set.
