眩光测量系统
摘要：
本发明能以低成本测量眩光评价中所需的眩光。眩光测量系统(1)具备：摄影机(2)，其以能够在水平面内旋转的方式被进行支撑；以及处理装置(4)，其基于所述摄影机(2)的摄影图像(7)计算出等效光幕亮度，并基于该等效光幕亮度计算出眩光等级(GR)值，所述摄影机(2)安装有超广角镜头(10)，并且在按照与所述超广角镜头(10)的视场角(α)相对应的每个角度在所述水平面内进行旋转的位置上进行摄影，所述处理装置(4)根据摄影图像(7)合成以眩光测量方向(C)作为中心的合成图像(30)，并基于该合成图像(30)计算出等效光幕亮度，并基于该等效光幕亮度计算出所述眩光测量方向(C)的眩光等级(GR)值。
摘要（英）：

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.
