Abstract: A glare measuring system is configured to have an imaging camera which is supported to be rotatable within a horizontal plane, and a processing device which calculates equivalent veiling luminance on the basis of a pickup image of the imaging camera and calculates the value of a glare rating GR on the basis of the equivalent veiling luminance. The imaging camera has a super-wide-angle lens mounted thereon, and picks up an image in a position which is rotated within the horizontal plane by every angle corresponding to the angle of view α of the super-wide-angle. The processing device combines pickup images to generate a composite image in which a glare measurement direction is set to the center of the composite image, calculates equivalent veiling luminance on the basis of the composite image, and calculates the value of the glare rating in the glare measurement direction.

Abstract: The luminance measuring apparatus for measuring the luminance of a road has an image pickup unit for picking up an image of the road, an input unit for inputting information concerning the road as an imaging target, and a luminance measuring unit for defining a luminance measurement target field A on the basis of the information input from the input unit and measuring the luminance within the luminance measurement target field A on the basis of an image picked up by the image pickup unit. The luminance measuring unit divides the luminance measurement target field A of the pickup image into a grid having a predetermined number of lattice intersection points MP in an equivalent of plan view, and allocates measurement points of luminance to the respective lattice intersection points MP.
