The digital image contains efficient and useful information which enables measurement and data acquisition. One of the methods that facilitate measuring and interpreting objects, using the image solely, is close-range photogrammetry. Among the various fields of science, whenever a precise measurement is required, this approach can be applied. One of these fields is Medical Sciences that due to ...

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...

Virtual 3D modeling is a very important and hot topic for researchers of Geomatics. Many scientists are working in this direction. All over the world, so many educational institutes are available with its own campus. Campus is the land on which Institute; College or University buildings are situated. In the modern digital era, the demand of 3D Campus is increasing. Virtual 3D model of campus gi...

This paper shows the current efforts in order to develop a digital photogrammetric softcopy kit which intends to provide a link between theory and practice in the field of Photogrammetry. These efforts have started in 2002, with the development of the first modules of the E-Foto kit: image viewer, project configuration, camera parameters, interior orientation and digital mensuration. The projec...

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...

This paper presents a basic theory of intelligent photogrammetry and corresponding physically independent agent systems named Photogrammetron. Intelligent photogrammetry is a fusion of ideas, techniques and applications from digital photogrammetry, active vision and intelligent agents, aiming at developing highly automatic and intelligent photogrametric systems. The tenet of intelligent photogr...

Airborne digital sensors are about to widen the choices in photogrammetry. The transition from analytical to digital photogrammetry is well advanced. Recent technology developments provide new solutions for high-resolution image acquisition for photogrammetric applications. These sensors are based on CCD-matrices as well as CCD-line sensors and fulfill both. The emphasis is placed on general pr...

Standard digital stereo photogrammetric systems are mainly designed to accomplish specific tasks and hence they may be regarded as problem oriented systems. However, for the solution of variety of conventional and non-conventional problems in computer vision and photogrammetry a vision based tool box may offer a great flexibility and adaptability for handling different tasks. In this paper the ...

The privacy of source code makes, in many situations, commercial application software unable to academic purposes. Such applicative programs are like “black-boxes”, allowing only data input and results output, as a function of the graphical user interface manipulation. It strongly hinders their application to education, since users remains alienated of what exactly is performed in the applicati...

This study aims to evaluate the reliability and establish procedures for the use of digital photogrammetry in anthropometric measurements of the human hand. The methodology included the construction of a platform to allow the placement of the hand always equivalent to a distance of the camera lens and to annul the effects of parallax. We developed a software to perform the measurements from the...
