Análisis técnico comparativo entre los métodos topográficos tradicionales y el método de aerofotogrametría con vehículo aéreo no tripulado

Abstract

The present study aims to apply the traditional topographic methods and the aerial photogrammetry method with UAV to obtain the topography of the park of study and reflection Latitude 0º, comparing the mentioned techniques to determine the advantages and disadvantages as well as the accuracy of the aerial photogrammetry in the project. The study was carried out as part of a linking project between Parque de studio y reflexión Latitud 0º and Escuela Politécnica Nacional, to deliver the topographic map. The data collection was performed with total station and GPS, in addition to capturing aerial photographs with the Phantom UAV 4. The processing of the photographs was done in Agisoft Photoscan to obtain a point cloud for export and complete the survey in Civil 3D AutoCAD with the data collected with traditional methods and thus obtain a digital model to generate the level curves. The conclusions written in the comparative technical analysis were made during the topographic survey, finding the advantages and disadvantages that were found in each section of the project. The comparative precision analysis was done in the area where a dense number of points were found, comparing the surfaces generated with each method. The topographic map was made use of the processed data of the methods and the writing to delimit the park of study and reflection Latitude 0 ° according to the present writings.
