Because of the complexity of the shapes of the structures of buildings, the glass curtain walls of such buildings have different geometries; some of these glass curtain walls have high reflectivity and can strongly focus incident solar light. Under ideal conditions, the solar radiation flux incident onto the glass curtain wall and the solar flux reflected from the glass curtain wall can be theoretically determined. When exposed to an intense light source, human eyes exhibit a visual masking effect when processing an image; the resulting noise level and signal-to-noise ratio in the image are studied. Using field measurements to measure the reflected sunlight of two types of glass curtain walls, the energy distributions of the light reflected from these two different glass curtain walls are determined. This paper focuses on analysis of the experimental results and the cause of the visual masking effect due to the reflection of sunlight from a glass curtain wall and on the method of quantitative calculation of the visual masking effect.
由于建筑物结构形状的复杂性，此类建筑物的玻璃幕墙具有不同的几何形状；其中一些玻璃幕墙具有高反射率，能够强烈聚焦入射太阳光。在理想条件下，理论上可以确定入射到玻璃幕墙上的太阳辐射通量以及从玻璃幕墙反射的太阳通量。当暴露在强光下时，人眼在处理图像时会表现出视觉掩蔽效应；对图像中产生的噪声水平和信噪比进行了研究。通过现场测量两种类型玻璃幕墙的反射太阳光，确定了这两种不同玻璃幕墙反射光的能量分布。本文重点分析实验结果以及玻璃幕墙反射太阳光导致视觉掩蔽效应的原因，并探讨视觉掩蔽效应的定量计算方法。
