Abstract:

The use of photogrammetry has been increased along the time, mainly due to the development of digital computers and photogrammetric algorithms. The E-FOTO project is being developed in the laboratory of photogrammetry of the UERJ. The E-FOTO main goal is to provide a GNU-GPL Educational, Digital Photogrammetric Workstation. This work presents a set of comparisons of the computations of photogrammetric parameters such as both interior and exterior orientations for a block of 1:30.000 digitized-frame imagery. 3D stereoscopic measurements of a set of photogrammetric testing points were also performed accordingly. The ERDAS LPS photogrammetry Suite was used as a basis for the comparisons of the results of the E-FOTO project. The results have shown so far the potential of use of the E-FOTO DPW software solution.
