玻璃幕墙的几何形状对反射太阳光引起的视觉掩盖效应的量化研究

Quantitative analysis of glass curtain wall reflection of sunlight caused the visual masking

由于建筑物外形结构的复杂性,出现了不同几何形状的玻璃幕墙,这些玻璃幕墙对入射太阳光有高的反射率和强的聚焦性。在理论上,推导出理想情况下,太阳光直射玻璃幕墙的辐射通量和玻璃幕墙对入射太阳光的反射通量;人眼成像过程中产生视觉掩盖效应时,整幅图像的含噪声水平和信噪比。通过实地测量的方法,分别测量出两种类型玻璃幕墙反射太阳光时,反射光线的能量分布情况。分析试验结果,得出玻璃幕墙反射太阳光造成人眼视觉掩盖效应的结论。

Because of the complexity of the shape structure of building,the different geometry of the glass curtain wall,the glass curtain wall with high reflectivity and strong focus on the incident solar. In theory,on the ideal condition,deduced radiation flux of incident solar to glass curtain wall and reflected flux of incident solar on glass curtain wall; visual masking effect of human in the process of image,the image containing noise level and signal to noise ratio. By the methods of field measurements,respectively to measure two types of glass curtain wall reflection of sunlight,the energy distribution of reflected light. Analysis of the experimental results,the glass curtain wall reflection of sunlight made the human eye visual masking effect.
