The modern World is constantly changing and education is one of the last things that do not get obsolete. However, its techniques must be adapted to newer resources and environments. Particularly, Photogrammetry is a science that has suffered from so many abrupt changes in the last fifteen years. We have passed from an enclosed and convergent dynamic characterized by Stereoscopic Aerial Photogr...

In this research we define optimal methods for 3D representation of devastated architectural objects. Recording devastated objects consists of three phases: recording existing remains, recording collapsed parts of objects and combining these results into a complete model. Optimal method for recording existing remains depends on the specific site conditions. Criteria for choosing optimal method ...

OBJECTIVES We aimed to compare the standard methods of cephalometry and two-dimensional photogrammetry, to evaluate the reliability and accuracy of both methods. MATERIAL AND METHODS Twenty-six patients (mean age 25.5, standard deviation (SD) 5.2 years) with Class II relationship and 23 patients with Class III relationship (mean age 26.4, SD 4.7 years) who had undergone bilateral sagittal spl...

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...

We describe an interactive system to reconstruct 3D geometry and extract textures from a set of photographs taken with arbitrary camera parameters. The basic idea is to let the user draw 2D geometry on the images and set constraints using these drawings. Because the input comes directly from the user, he can more easily resolve most of the ambiguities and difficulties traditional computer visio...

The combination of scanning electron microscopy for high spatial resolution, images from multiple angles to provide 3D information, and commercially available stereo photogrammetry software for 3D reconstruction offers promise for nanometer-scale dimensional metrology in 3D. A method is described to test 3D photogrammetry software by the use of virtual samples-mathematical samples from which si...

Network orientation is a fundamental step in image-based 3D measurement. This paper aims to offer insights into network orientation by considering developments in analytical close-range photogrammetry during its evolution from a film-based to digital image-based measurement technology suited to full process automation. A brief mathematical background to orientation models derived via perspectiv...

The study utilises two emerging low-cost technologies, low cost Remotely Operated Vehicle (ROV) and underwater photogrammetry techniques (Structure from motion (SfM)) using off the shelf cameras, for 3D reconstruction of shallow hydrothermal vent sites around Paleochori Bay, Milos Island, Greece. Venting fields were Characterised through interactive bathymetry models produced from still images ...

This is a report on a methodological adaptation of the photogrammetric technique, which is used in other medical specialties, for use in analyzing respiratory movements. Photogrammetry and a model of photogrammetry designated biofotogrametria para análise da mecânica respiratória (BAMER, photogrammetric analysis of respiratory mechanics) were tested under previously described pathophysiological...

We review work on image-based 3D modelling. 3D modelling entails the availability of complete 3D coordinates, and yet obtaining the coordinates is one of the most difficult tasks. Resorting to using 2D images appears a promising means to achieve this task and has been much reported. Prevalent methods are the shape from shading, photometry, stereopsis, photogrammetry and the video approach. Shap...
