Rock mass structural characterization via short-range digital photogrammetry

Because of the important role of rock mass structural properties on its mechanical behavior, determining the qualitative and quantitative properties of has been a subject of intense research. In this regard, numerous techniques such as scanline surveying, cell mapping, and geologic structure mapping have been proposed. However, applying such field surveying techniques for rock mass properties i...

Digital Terrestrial Photogrammetry with Photo Total Station

Terrestrial photogrammetry is engaged in measurement, contour delineation or 3D reconstruction with photos captured by a camera located on the ground. Terrestrial photogrammetry has gained wide applications in many fields such as 3D building reconstruction, heritage protection and so on. In this paper, a new instrument named photo total station system has been adopted and meanwhile based on thi...

Application of Digital Photogrammetry in Geotechnics

Acquiring geometric data, such as coordinates, displacements or deformations, has always been a way to verify mathematical modelling in civil engineering. The introduction of finite elements methods further reinforced this trend. This paper reports on two applications of photogrammetry to soil and rock mechanics in order to provide an accurate and dense description of the deformation fields of ...

Accident Reconstruction via Digital Close-range Photogrammetry

With the ever wider adoption of spatial information analysis, there has been an increasing awareness of the importance of 3D data acquisition systems to support traffic accident reconstruction and forensic analysis. In an application such as accident reconstruction, GIS and CAD systems have limited utility without the underlying data. Digital close-range photogrammetry displays many attributes ...

Digital Orthoimages in Architectural Photogrammetry Using Digital Surface Models

The paper describes a new approach for the generation of architectural orthoimages using digital surface models, based on a CAD model of the object. The model is supposed to consist of surface elements, plane or curved. All surface elements of the CAD model are orthogonally projected onto the reference plane. For each grid element the elevation above or below the reference plane are calculated ...
