METHOD FOR DIAGNOSING OUTER COAT DISCOLORATION
To provide a method for diagnosing outer coat discoloration of a building that identifies the brightness of an outer coat more accurately from an image of the outer coat of the building taken with an imaging device and can accurately diagnose deterioration of the outer coat from the brightness.SOLUTION: A discoloration diagnosis method calculates the brightness of a second roof 21 and the brightness of a standard plate 9 as evaluation brightness from an image of the standard plate 9 together with the roof 21 of a second building 20 different from a first building 10 captured with an imaging device 6. The evaluation brightness of the standard plate 9 is substituted into a function F of a pre-calculated correction coefficient K and the evaluation brightness of the second roof 21 is corrected by an obtained correction coefficient KB of the evaluation brightness of the second roof 21. The discoloration of the second roof 21 is diagnosed from the corrected evaluation brightness of the second roof 21.SELECTED DRAWING: Figure 2
【課題】撮像装置により撮像された建物の外皮の画像から、より正確に外皮の明度を特定し、この明度から外皮の劣化を正確に診断することができる建物の外皮の退色診断方法を提供する。【解決手段】この退色診断方法では、第１建物１０と異なる第２建物２０の屋根２１とともに標準板９を、撮像装置６で撮像した画像から、第２屋根２１の明度と、標準板９の明度とを、評価明度として算出する。標準板９の評価明度を、予め算出した補正係数Ｋの関数Ｆに代入し、得られた第２屋根２１の評価明度の補正係数ＫＢで、第２屋根２１の評価明度を補正する。補正した第２屋根２１の評価明度から、第２屋根２１の退色を診断する。【選択図】図２
