APPLICATION OF GLARE IMAGE TO VISUAL ENVIRONMENT DESIGN OF RESIDENCE

摘要

One of the most important factors for improving visual comfort is to decrease discomfort glare in our visual field. It is not an exception in design of housing. However, a luminance distribution in a house is often very complex. For this reason, we should develop a new estimation method of discomfort glare. Therefore, we have developed a convert system to obtain a glare image using wavelet transform from a luminance image. With use of this system, we can easily obtain equivalent value of UGR index in a complex luminance distribution. If we want to design a comfortable house, we should perform lighting simulation and obtain luminance distribution in a room. We can evaluate the results of simulation by using the glare estimation method proposed here. Now we have a means to reduce discomfort glare even in the design stage.
