Method of Estimating Construction Year of Wooden Houses from Pictures of Exterior Appearance

Abstract

We studied a method of estimating construction years of wooden houses from pictures of exterior appearance. First, we performed estimation tests using wooden houses whose construction years were known to make sure the accuracy of the method. We confirmed that the construction year distribution of wooden houses could be estimated with an error of less than 5% pt by judging 5 or more people. Finally, we estimated construction year distribution by using this method around the strong ground motion observation points.
