  • Three-dimensional modeling of the Kubbe-i Hasiye Shrine with terrestrial
           photogrammetric method

    • Authors: Fatih PULAT; Murat YAKAR, Ali ULVİ
      Abstract: Natural and unnatural structures, which are the subject of our cultural heritage, are in constant danger of extinction as a result of both man-made destruction and natural events such as natural disasters, rains and strong winds. Therefore, it is necessary to take very good protection measures in order to keep cultural assets alive and transfer them to future generations. In the light of today's technology, different techniques have been developed to take these protection measures. One of these techniques is terrestrial photogrammetry technique. With this technique, all the details of the building are measured and a three-dimensional visual model of the building can be created thanks to the pictures of the building. Thus, by recording all the features of the building such as detail dimensions, shape, size, type of building material, necessary interventions can be made in case of any structural deterioration, modification and repair that may occur in the building. In this study, it is aimed to measure the Kubbe-i Hasiye tomb located in the center of Tillo district of Siirt province, photogrammetrically, and to make a three-dimensional modeling with the pictures taken of the tomb by making three-dimensional modeling. As a result of the measurements made on the model obtained as a result of the study, precision was obtained in the reference intervals determined and the amount of error was determined below 2 cm.

  • 3D modeling of historical artifacts with terrestrial photogrammetric
           method: Roman sarcophagus and tomb stele example

    • Authors: Gizem BAŞ; Aydan YAMAN
      Abstract: Many societies, civilizations and states have lived on the lands of Anatolia, the cradle of cultures and civilizations, from the past to the present. Each of these civilizations and states has left many works. It is very important to protect the material and moral works left to us, and transfer them to the next generations. Documentation studies should be carried out for this purpose. There are many methods for performing documentation work. The most important of these methods is the studies in the field of photogrammetry. With the photogrammetry method, the objects are modeled in three dimensions (3D) and recorded in the computer environment, and these data can be used at any time for the repair or reconstruction of the work in case of any deformation. The concept of 3D is the concept that emerges by knowing the width, height and height dimensions of the objects. One of the methods that can be used to model objects in 3D is the terrestrial photogrammetry method. With the terrestrial photogrammetry method, after the necessary data are collected from the objects, a 3D model is obtained using various software in the computer environment. In the modeling phase, it is very important to find the appropriate software. In this study, it was aimed to model the sarcophagus and tomb stele from the Roman period in Aksaray Museum using two different software. Agisoft Metashape and Pix4d software were preferred for 3D modeling. The results obtained from the software was compared in terms of the number of photos and the number of point clouds used and location accuracy. It has been observed that the error values found by the square mean error method in Agisoft software are lower than in the Pix4d software. It was observed that the Pix4d software produced more point clouds while modeling. An equal number of photographs were used in modelling.

  • 3D modeling of historical theodolite with photogrammetric techniques and
           accuracy analysis

    • Authors: Muhammed Enes ATİK; Zaide DURAN, Mustafa YANALAK, Dursun Zafer SEKER
      Abstract: As historical artifacts are the common heritage of all humanity, preserving historical artifacts is very important in keeping the cultural heritage alive and passing it on to generations. Creating scale models of these works and transferring them to digital media is a useful method for reproduction and documentation. In this study, an experiment on 3D modeling of historical artifacts exhibited in the Museum of Geomatics Engineering Department of Istanbul Technical University using photogrammetry and 3D scanning methods is presented. Theodolite (19th century) in the museum were modeled in 3D using photogrammetry and 3D scanning methods, and accuracy analysis was performed. For real values, length measurements were made with calipers over the models. According to the results obtained, the accuracy is 7.3 mm photogrammetric model and 1.3 mm for the 3D scanner model.

  • The production of line-drawing and 3D modeling of historical Mehmet Ali
           Bey Fountain with SFM approach

    • Authors: Naci YASTIKLI; Zehra ÇETİN, Erdal ASAMAKA
      Abstract: Historical and cultural artifacts provide information about ancient life, language, religion, literature, traditions and architecture. Documentation of cultural artifacts is of great importance in terms of protecting and transferring them to future generations. In recent years, Structure from Motion (SfM) can be used to generate dense point cloud, ortho-image, line-drawings, and 3D models in addition to the classical terrestrial photogrammetry methods. The fast documentation and archiving studies can be carried out by SfM approach using low-cost cameras with cost effective project budget. In this study, it is aimed to produce line-drawing, ortho-image, and 3D models of Mehmet Ali Bey Fountain by using SfM approach. The Mehmet Ali Bey Fountain is one of the registered historical structures in the "Monuments" class among registered immovable cultural assets throughout Turkey, located in the Abbasaga District of Besiktas/Istanbul from the Ottoman Sultan II. Mahmut period. The installation and measurement of the control points were conducted, and the image acquisition was performed with convergent image acquisition method. The 3D point cloud generation of Mehmet Ali Bey Fountain was performed after image orientation steps. The productions of 3D model, ortho-image, and line-drawing have been carried out successfully using the produced point cloud. In this study, all processes for the documentation of historical structure were carried out using “Agisoft Metashape Professional” and “Autocad” software. The analyzed measured distances between the GCPs and corresponding distances from 3D model (standard deviation of the differences is 0.5 cm) proved the success of the SfM method for documentation of registered historical artifacts and cultural heritage.

  • The digital memory for the cultural heritage in the 21st century

    • Authors: Lale YILMAZ
      Abstract: The concept of memory has been redeveloped since the beginning of the 20th century. Social memory is directly related to the cultural heritage, which includes memory, and the protection and transfer of heritage. Technological applications that ensure sustainability of tangible and intangible cultural heritage in the 21st century are included in cultural institutions and internationally UNESCO projects. In this study, it was aimed to evaluate the concepts of memory, about the using in the international and historical documents of the cultural heritage. In the study, the concept of memory was focused in terms of cultural heritage, and the technological applications developed against the loss of information and documents of universal value were examined. The Memory of the World Register developed by UNESCO in 1997, is within the scope of documentary heritage. From Turkey, Observation and Earthquake Research Institute Kandilli Observatory Manuscripts, Hittite Tablets, Süleymaniye Library Ibn-i Sina Manuscripts Collection, Evliya Çelebi Travel Book, Kultepe Tablets, Divan-ü Lügâti’t-Türk and Piri Reis’s Map, Karatepe Tablets recorded in the list. As a result of the study, the importance of transferring information and documents that have universal value as a world heritage to digital media has been emphasized and the aspects of the using technology in culture have been evaluated.
