In close-range images, normally a large number of geometrical features is available. For photogrammetrists, the detection of shapes such as straight lines is very useful. These features are very helpful for further photogrammetric work, such as sensor calibration, image orientation, DTM generation etc. Hough Transform (HT), is such a powerful tool for detecting predefined shapes (i.e. lines, el...

In this paper, we show that a 3D laser scanner tracking system can be efficiently used in a projective mode similar to photogrammetry-based methods. The best of both laser ranging and photogrammetry can be combined to incr...

Abstract. Civil infrastructure Structural Health Monitoring (SHM) and its preservation from deterioration is a crucial task. In general, natural disasters like severe earthquakes, extreme landslides, subsidence or intensive floods directly influence the health of civil structures such as buildings, bridges, roads, dams. Evaluation inspection defects damages aforementioned help to preserve them ...

We describe an innovative system designed for museums to create, manage and present multimedia based representations of museum artefacts in virtual exhibitions both inside and outside museums. Our system creates digital surrogates through a novel stereo photogrammetry system with little user interaction. The resulting 3D objects are refined using state-of-the-art 3D modelling software configure...

The use of consumer grade digital cameras for spatial measurement has rapidly increased over the past decade and is accepted in many industrial applications but also in diverse fields ranging from medical science to architectural work. Their uncertain internal geometry can be partially resolved by calibration. Research recent conducted at Loughborough University indicated the potential of consu...
