Sistema de planificacion de vuelos para la reconstrucción 3D de edificios a partir de imagenes aéreas

Abstract

The drone industry has grown notably during the last years. There are many applications that can be carried out in different fields, with special interest in architecture and civil engineering, where from three-dimensional models of buildings, built from images taken by drones, you can perform tasks like diagnosis, monitoring, documentation and surveillance of these. The technique used to make three-dimensional models from photographs is known as photogrammetry. Currently one of the techniques most used for three-dimensional reconstruction of buildings is laser scanning, however, it is much more expensive than the first and it's harder to do. The present project argues the development of a system that allows to plan the route of a dron around any building avoiding any type of obstacles, the algorithm used to obtain this route will be based on the optimization algorithm of Branch and Bound. The objective will consist in find the most optimal result, in other words, the shortest route. In addition, the zones of this route will be defined where the necessary photographs will be taken to perform the three-dimensional reconstruction of buildings. Finally, a file will be created to carry out the mission, this file will contain the differents commands of navigation and sensor activation. To accomplish this, a WPF (Windows Presentation Foundation) desktop application that simplifies and accelerates the process has been developed, with an attractive and user-friendly interface.
