Deviation Analysis of Historical Building Basedon Terrestrial Laser Scanner Dataand 3d Mesh Model
(2022) Sayar, Recep; Güleç Korumaz, Saadet Armağan
The useof Terrestrial Laser Scanner (TLS)technologiesin cultural heritage studies has becomemore common day by day. In addition to documenting a historical buildingwith high accuracy, TLS technologiescan obtain detailed data about the structurebeing studied by analyzing point cloud. Laser scanning data is seen as a non-contact and effective analysis method in determining the formal deformations that occur due to various reasons, especially in historical buildings. With this method, it is possible to determine how much the object deviates from a reference 3D model or plane and with this analysis, deformation maps can be prepared. With the help of these maps,intervention decisions can be made. Within the scope of the article, laser scanning data of Selime Sultan Tomb located in Güzelyurt Selime Townin Türkiye, one of the important settlements of Cappadocia, wereacquired.By comparing the 3Dmesh model prepared with base on pointdata, the morphological differencesand deviations of the tomb were determined and mapped.
Lidar To Hbim for Analysis of Historical Buildings
(2021) Özeren, Ömer; Korumaz, Mustafa
The design, documentation and construction processes in Architecture, Engineering and Construction industries (AEC) have been undergoing majör changes in recent years with Building Information Modeling (BIM). The use of BIM togetherwith 3D laser scanning (LIDAR) technologies has brought great innovations by going beyond traditional methods in studies carried out in historical environments. With the developed of used technologies together with Heritage Building Information Modeling (HBIM), efforts documentation and rehabilitation of historical buildings have rapidly increased in the last ten years, especially in European countries. This article provides a framework for the implementation of LIDAR to HBIM related to heritage buildings in Turkey. An approach is carried out a process that is a workflow from document historic structures with 3D laser scanning and subsequently generation of a HBIM model. The process of producing an different detailed of HBIM models for provide the documentation and restoration needs of historical buildings from point clouds and processed point clouds for using different platforms was carried out as a case study.
Terrestrial Laser Scanning With Potentials and Limitations for Archaeological Documentation: a Case Study of the Çatalhöyük
(2021) Güleç Korumaz, Saadet Armağan
The evolution of digital technologies has impacted the documentation of cultural heritage. One of the steps that have passed considerable change is maybe the stage of data collection field. Today many different technological tools may be found at affordable prices. The suitable method for cultural heritage documentation should be chosen considering the needs of research, analysis and conservation. There is no definite way in order to determine which survey technique is the most suitable one in any situation. Digital photogrammetry, total station, GPS, texture mapping, laser scanning techniques are mostly preferable when high accuracy needed and can be supported by traditional tools like rectified photographs and stereophotogrammetry. In recent years, laser scanningshows great versatility for capturing any type of shape and speed of data acquisition. However in some cases, Terrestrial Laser Scanning (TLS) can have some limitations. In this study, Çatalhöyükarchaeological area was documented with TLS and experiences were shared as potentials and limitations of TLS for archaeological documentation.
