It is important to know cutting and filling volumes in many survey, engineering and mining works. Volume calculation, generally, are completed with classic surveying methods. The trapezoidal method (rectangular or triangular prisms), classical cross sectioning (trapezoidal, Simpson, and average formula), and improved methods (Simpson-based, cubic spline, and cubic Hermite formula) have been pre...

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 ...

A procedure for an automatic search and measurement of artificial targets in digital images for elose-range photogrammetric applications is presented. Photographs taken with a sem i metric 6x6 camera were digitized by the "ASTROSCAN" at the Sterrewacht Leiden. The especially designed targets contain a circular barcode for automatic identification. It is shown that this procedure improves both p...

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...

Recently, the documentation and visualization of various cultural assets have been receiving attention. For example, a small Buddha less than 10 cm in height and located in the womb of a larger Buddha is considered as a cultural asset. In this study, the authors have considered the use of macro lens to perform digital very close range photogrammetry for small objects. It was demonstrated that a...

The objective of this study was to investigate the capabilities of low-cost digital cameras in volume determination. Low-cost digital cameras are capable of many applications including aerial photogrammetry and close-range photogrammetry. Low-cost digital cameras have the potential to be used in landslide monitoring and mapping. In this study, a low-cost digital camera was used as a tool to acq...
