3D Modeling of Mufti Abdullah Sıddık Mosque using Wearable Mobile LiDAR

Atilla Karabacak — 2023-03-31

Mobile LIDAR, which can be attached to any moving vehicle, started to be used after 2000. In recent years, Wearable Mobile LiDAR (WML), which can be carried by wearing it on a person, has started to be used. WML is used for mapping and 3D modeling of interior and narrow places that cannot be reached by any vehicle and only one person can enter. In this study, 3D model and orthophoto of Mufti Abdullah Sıddık Mosque located in Mersin University Çiftlikköy campus were produced. With WML, data were collected in a short time like 13 minutes in the field and the produced orthophoto and 3D models were produced within the error limit. When the system is used fast and based on Ground Control Points (GCP), it gives results within the error limits. This study demonstrates the usability of WML in structure modeling and mapping.

3D Laser Scanning and Photogrammetric Measurements for Documentation of the Facades of Mardin Castle, Türkiye

Lale Karataş — 2023-03-31

Mardin Castle is a cultural heritage of approximately 900 years and is located in the 1st Degree Archaeological Site. The castle has an east-west extension and contains Roman-Byzantine artifacts as well as many structures from the Islamic period (Mervani, Akkoyunlu, Artuklu).The entire length of the building is approximately 850 m when viewed from the south side at a right angle. Architectural documentation of the façades of such a gigantic building is a subject that requires a long time and effort with traditional methods and has a high risk of error. The main purpose of this article is to document the ruins of the southern facade of the Mardin castle and the rocky cliffs with architectural drawings. For this purpose, it has combined different analytical and investigation techniques such as terrestrial laser scanning, photogrammetry and observational analysis. In the study findings, facade surveys of the facade of the castle were obtained. The results of the study confirm that methods such as terrestrial laser scanning technology save a great deal of time and effort spent in the process of documenting huge structures such as castles.

Analysis of 3D Laser Scanning Data of Farabi Mosque Using Various Softwaren

Shah Wali Nazari — 2023-03-31

Three-dimensional laser scanners, which offer an alternative solution to traditional measurement methods, have enabled geomatics engineers to have much higher confidence in the accuracy of their measurements. When high-resolution data used in many different measurement applications, including 2D and 3D drawings, calculations such as area and volume calculations, and topographic measurements are evaluated, it is understood that the resolution and efficiency provided by traditional measurement methods are far inferior. Obtaining data about objects and gaining information about objects by evaluating this data in a computer environment, obtaining 3D images of objects one-to-one is an important issue today. As a result of the development of computer technology and laser scanning systems over time, Terresterial Laser Scanners (TLS) have rapidly begun to be used today. With the TLSs, the 3D geometric and visual information of objects can be obtained accurately, quickly, one-to-one and at low cost. In this study, the 3D model of the exterior of Farabi Mosque located on the Farabi campus of Bülent Ecevit University was obtained and evaluated in different softwares. After a successful merging of the data model, due to the limited functions of Faro Scene 2019 software, area calculation, mesh creation, and volume calculation operations were performed on the cloud data using Autodesk Recap 2020 V6.0, Gexcel Reconstructor 2020 V4.2.0, and Meshlab 2020.07 software, and operations were carried out on cloud data that looks close to reality.

Application of Terrestrial Laser Scanning (TLS) Technology for Documentation of Cultural Heritage Buildings and Structures: A Case Study Sarı İsmail Sultan Tomb

Sena Köse — 2023-03-31

Türkiye is a very rich country in terms of historical artifacts. It is extremely important to document these artifacts in order to preserve them and transfer them to future generations. In documentation studies, Terrestrial Laser Scanning (TLS) method has started to be preferred with the developing and advancing technology. In this study, the usability of the data obtained by the TLS technique in the documentation of cultural heritage was investigated. The study area, Sarı İsmail Sultan Tomb, was scanned with a terrestrial laser scanner using TLS technique, the scan data were combined in a commercial software and a 3D model of the cultural heritage was created.
