A survey of column-leaning in Korean traditional wooden architecture structures using 3D scandata with a focus on the columns of the Sungryeoljeon in Namhansanseong

Colum-leaning in Korean traditional wooden heritage structures has been emphasized in various reports since the first survey report from the 1950s. Recent technological advancements have granted researchers to use 3D scandata to examine column-leaning. This paper discusses the methods of measuring and representing column-leaning in the Soongryeoljeon in Namhansanseong - a UNESCO designated World Heritage site - using 3D scandata.
