UTILIZAÇÃO DA FOTOGRAMETRIA PARA LEVANTAMENTOS TOPOGRÁFICOS NA CONSTRUÇÃO CIVIL

Abstract

This work addresses the use of photogrammetry for topographic surveys in the construction. Such an approach is due to the fact that the use of aerial vehicles does not manned makes it easy to obtain data from large areas. The objective of this work is to evaluate the application of aerophotogrammetry techniques and compare it with conventional methods. This one purpose will be achieved through a study on photogrammetry and the realization of a topographic survey project using the image data obtained through a unmanned aerial vehicle. The study demonstrated that, compared to the total station, of aerial photography in topographic surveys tends to be more practical and agile in areas bigger, in addition to less labor and cost reduction as a consequence but not it has the millimeter accuracy that the use of the station provides us, but centimeter. THE case study proved the efficiency after data processing in the software in measurement and development of digital models.
