Sponsors
Written by Super UserFrom 2004 and 2007, the CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico) agency sponsored eproject E-foto. Nowadays, other institutions provide support to the project, mainly UERJ (State University Rio de Janeiro), with grants for thecnical support (PROATEC), undergraduate research and trainee. The Brazilian Army (Exército Brasileiro/ Diretoria do Serviço Geográfico) also have sponsored this project by a cooparation to the develpment of the photogrammetric module of the project SIG-Desktop.
We also are grateful to other institutions wich have provided support to us: Funcate, Instituto Militar de Engenharia , Instituto Brasileiro de Geografia e Estatística, Companhia de Pesquisa de Recursos Minerais, Instituto Municipal de Urbanismo Pereira Passos and TopoCart.
This module aims to reconstruct the internal geometry of the internal perspective rays of the camera, which does the image referencing (image plane) in relation to the camera (the camera optical axis). The Interior Orientation must be run for each photogrammetric images. To follow this tutorial you need the .epp file generated in the project management tutorial.
Phototriangulation is a technique for calculating and adjusting perspective center coordinates and sensor attitude angles at the time images were acquired. This allows the reconstruction of spatial (terrain) coordinates from imagery.
This module aims to achieve three-dimensional photogrammetric restitution of the land surface represented in a stereoscopic model.
This module allows users to extract a Digital Elevation Model from a set of imagery belonging to a photogrammetric project. In other words, it creates a 3D model of a section of land.
An orthoimage is, by definition, an image
