Background Digital photogrammetry provides measurements of body angles or distances which allow for quantitative posture assessment with or without the use of external markers. It is becoming an increasingly popular tool for the assessment of the musculoskeletal system. The aim of this paper is to present a structured method for the analysis of posture and its changes using a standardized digit...

Background Scoliosis patients typically undergo numerous spinal radiographs and exposed to relatively high doses of ionizing radiation. This has raised concern regarding the effects of this repeated exposure. Additionally assessment of spinal deformities using surface topography of the back is currently considered essential. Digital Photogrammetry can contribute in non-invasive measurements of ...

Digital photogrammetric methods have made their way also into architectural applications which is traditionally a rather conservative branch. Beside the programs and techniques that have been adopted from aerial photogrammetry mainly low-cost systems are used for architectural and archaeological applications. New strategies for data acquisition, restitution and presentation of the digital data ...

The paper presents some applications realised with the digital stereoscopic navigation system on two architectural subjects and particularly on documentary photograms of mural paintings. The system StereoSpace is a three-dimensional stereoscopic navigator, specifically thought to be used in digital photogrammetry.

Three dimensional architectural models are more and more important for a large number of applications. Specialists look for faster and more precise ways to generate them. This paper discusses methods to combine methodologies for handling data acquired from multiple sources: maps, terrestrial laser and additional measurements, together with digital images for the purpose of generating the 3D vis...

Abstract Most parts of the Earth’s surface are situated in deep ocean. To explore this visually rather adversarial environment with cameras, they have to be protected by pressure housings. These housings, turn, need interfaces world, enduring extreme pressures within water column. Commonly, a flat window or half-sphere glass, called flat-port dome-port, respectively is used implement such kind ...

Photogrammetry and laser scanning, thanks to significant development in last years, are comparable surveying techniques to generate without object contact and with a precision commensurate with scale Digital Terrain Models (DTMs), a fundamental tool to detect, classify and monitoring landslides. The traditional way to survey the territory for landslide detection purposes is aerial or, in some c...

Classical methodologies used in data collection for architectural documentation are studied (surveying topographic, photogrammetry, manual methods, etc). Different aspects are analysed in order to select the most suitable approach, always taking into account the specific determining factors. The suggested technique is in line with the so-called close range photogrammetry by simple methods. Its ...

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 ...

A convenient 3D measurement using amateur digital camera is enormously expected from various fields according to appearance of the high resolution amateur cameras since pixel numbers of amateur digital cameras are amazingly increasing by modern semiconductor and digital technology. In these circumstances, software for low-cost digital photogrammery “3DiVision” was designed to perform convenient...
