<p><P>PROBLEM TO BE SOLVED: To define the life of the outward appearance durability of the whole of a building to diagnose the deterioration in the appearance of the building. <P>SOLUTION: The appearance member of the building is separated into groups at each color phase. Color difference after a secular change to an initial stage is measured with respect to the member having a base color of each group and it is determined whether the measured color difference is +6(=ΔE) or above to diagnose the deterioration of the member having the base color. Further, with respect to a member having a color other than the base color, the color difference after a secular change to an initial state is calculated and it is determined whether the difference between the calculated color difference and the color difference of the member having the base color is +6(=ΔE) or above to diagnose the deterioration in the appearance of the building. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
