ABSTRACT
The historical structures and their heritages have been measured for documentation, touristic information
and three-dimesional (3D) visualization on virtual museum. Many of the historical structures have complex
details and difficult conditions to measureing of their all details. The proper measurement method should be
selected for fast, lowcost and high accuracy 3D modelling of a great number of historical heritages. The
image based methods of photogrammetry and dense point cloud are extensively used for three-dimensional
modelling thanks to its low cost and easy implementation. In this study, historical masonry arch
Dokuzunhan Bridge was measured for 3D modelling by using photogrammetry and dense point cloud
methods, and the results of the methods were compared. The results show that these methods are accessible
and affordable methods for 3D modelling of masonry arch bridges.
