dc.description.abstractIn civil and mining engineering areas, close range photogrammetry (CRP) has been used in recent years to investigate various aspects of rock faces such as geological structures, weathering, and crack propagations. The 3D models of CRP are efficiently used for the mapping and characterization of rock slopes on the cost-effective and less labor-intensive advantages of digital photogrammetry. The recent development of high-end equipment for remote sensing surveys in the field of digital cameras and photographing technology has also encouraged the spread of CRP to obtain accurate geomorphological data from the photogrammetric 3D images. The roughness of rock joint planes is a crucial factor to investigate the shear strength and the groundwater infiltration characteristics along the joint planes. In geological and geotechnical purposes, the degree of roughness is identified by roughness parameters and the values are obtained from observations using large and small scale profiles in laboratory and field conditions. As a representative parameter, the rock joint roughness coefficient (JRC) has been widely employed combined with its strength characteristics. In order to measure the surface roughness, manual measurements using a profile gauge have been traditionally taken in both laboratory and field investigations. This mapping process is quite labourious and involves risks during field work. For this reason, close range photogrammetry has advantages over the traditional mapping methods in reducing surveying time and minimizing possible risks involved in field work.
