Procedimentos de processamento aerofotogramétrico utilizando o software E-foto em comparação com os cálculos realizados com o auxílio de uma planilha eletrônica

Abstract

The present project aims to demonstrate a brief history about photogrammetry as well as its concept and the procedures for the performance of rendering of photophotography. These are a flight over the city of Rio de Janeiro, on December 9, 1995. The photographs were supplied together with the e-foto software, which was used to carry out the processing of the photographs, these, which were the interior orientation and exterior orientation of each photo. After carrying out the processing of each of the aerial photos, the extraction of the pixel coordinates of each image was then started in the paint software, where they were inserted in a spreadsheet in the excel software in order to compare the results returned from the closed code (e- photo), with the results returned from the spreadsheet (excel). When performing these comparisons, it can be observed that the data return from the e-foto software was very satisfactory, since it has a closed code. The spreadsheet also showed efficiency, where it shows a number of equations necessary to present an approximate result to that of the e-foto software. It is worth mentioning that the electronic spreadsheet demonstrates how manual calculation is performed, thus making the user not dependent on closed source software to obtain results.
