Terrestrial Laser Scanners (TLS) have gained momentum in identifying cracks and deformations. Although TLS efficiency has been recognized over time, the scan data quality is contingent upon various parameters (e.g., material type and scan settings), which impacts the use of TLS. To address this barrier, this study investigates the measurement accuracy in the context of crack analysis in foam board and common building materials (concrete, wood, and masonry) by conducting a set of controlled experiments with different scan settings (e.g., scan dis-tance and angle of incidence). The findings of this study provide practical contributions to using TLS for crack identification, specifically addressing the effect of different parameters on point cloud data quality and proposing boundary ranges for different scan settings regarding different building materials and crack widths to facilitate TLS planning.

Investigation of Terrestrial Laser Scanning Reflectance Intensity and RGB Distributions to Assist Construction Material Identification Hassan, Muhammad Usman; Akçamete Güngör, Aslı; Akgül, Çağla (2017-07-07) t: Terrestrial Laser Scanning (TLS) allows collection of dense 3D point cloud data that captures a structure's as-is conditions. The geometric information from the collected data could be used to generate a 3D-model of the structure. However, the generated model usually lacks functional information - a basic requirement for a semantically rich information model. Some of the functional information (such as cost, mechanical and thermal performance) could be derived if the material used in a particular geometr...
Effect of production parameters on porosity and hole properties in laser sintering rapid prototyping process İlkgün, Özkan; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2005) Selective laser sintering (SLS) is a rapid prototyping method in which three-dimensional objects are constructed by sintering thin layers of a variety of powdered materials via laser beam. In SLS, as in most other Rapid Prototyping methods, the produced parts exhibit varying degrees of intrinsic porosity due to the discrete nature of layer-by-layer production. Selective scanning and discrete bonding of individual particles or clusters of particles impart local porosity, which is mostly an undesired trait as...
Effect of synthesis parameters on the surface morphology of conducting polypyrrole films Kaynak, A (1997-03-01) Surface morphology of polypyrrole films was investigated by using atomic force and scanning electron microscopy techniques. Synthesis parameters such as dopant concentration and synthesis time and subsequent heat treatment were found to affect the surface morphology of electrochemically synthesized polypyrrole films. Mean height, root-mean-square roughness, and nodule diameter increased with increasing dopant concentration and synthesis time. Lightly doped, semiconducting films had smoother surface morpholo...
A Graph Signal Filtering Based Approach for Detection of Different Edge Typeson Airborne LiDAR Data Bayram, Eda; Vural, Elif; Alatan, Abdullah Aydın (2017-09-12) Airborne Laser Scanning is a well-known remote sensing technology, which provides a dense and highly accurate, yet unorganized point cloud of earth surface. During the last decade, extracting information from the data generated by airborne LiDAR systems has been addressed by many studies in geo-spatial analysis and urban monitoring applications. However, the processing of LiDAR point clouds is challenging due to their irregular structure and 3D geometry. In this study, we propose a novel framework for the d...
Effect of Sn Alloying on the Diffusion Bonding Behavior of Al-Mg-Si Alloys Atabay, SILA ECE; Esen, Ziya; Dericioğlu, Arcan Fehmi (2017-07-01) Effect of Sn as an alloying element on the diffusion-bonding behavior of Al-Mg-Si alloy has been studied by means of differential scanning calorimetry (DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM) and mechanical testing of the diffusion-bonded joint. XRD results revealed the formation of Mg2Sn and (Sn) phases during solidification following induction casting. DSC results showed local liquid (Sn) formation during the bonding process for Sn-containing alloys, where its amount was found to...
