Application of Close Range Photogrammetry to Deck Measurement in Recreational Ships
In this article, we present results that demonstrate the utility of close range photogrammetry in the measurement of decks in recreational craft as an alternate measurement system to the one based on direct acquisition of coordinates. The areas of deck covered with teakwood for aesthetic or security reasons were measured. Both methods were compared in terms of precision of measurements, time co...
متن کاملHybrid Measurement Scenarios in Automated Close-range Photogrammetry
Automated close-range photogrammetric measurement has traditionally been associated with expensive specialist cameras and usually requires highly controlled image illumination conditions. In the past few years, however, there has been a significant amount of research into the development of automated routines and algorithms that support the employment of consumer-grade colour digital cameras fo...
متن کاملAn Application of Close Range Photogrammetry in Dolphin Studies
Dolphins are agile animals and are very difficult to measure at sea. However, for the conservation of threatened or endangered species, measurement may be vital because it allows a demographic analysis of the population. Hector’s dolphin (Cephalorhynchus hectori) is a rare species living only in coastal waters around New Zealand where it is studied from small boats. This paper describes a stere...
متن کاملAdvances in Close-Range Photogrammetry
This paper presents a general overview of notable developments in close-range photogrammetry (CRP) over the past four decades, during which time both automated processes were introduced and the full transition from film-based to digital imaging cameras occurred. With these developments and more recent innovations centred upon so-called structure-frommotion approaches to network orientation, alo...
متن کاملClose Range Photogrammetry for Measurement of Paintings Surface Deformations
The paper describes the first results about a study on the measurement of paintings surface deformation. The study was carried out using one ancient painting model made in a restoration laboratory and consolidated with the materials and dilutions most frequently used in the field of conservation. The restorers suppose deformations of the paintings surface from 0.1 mm to some millimetre when the...
