Development of a 3D digital model using photogrammetry with drones

Being construction one of the sectors in which more is invested and that, according to the OECD (Organization for Economic Cooperation and Development), contributes 13% of GDP worldwide, curiously it is also one of the activities that shows lower rates of productivity in the last 25 years according to a study prepared by the McKinsey Global Institute (2017).In different stages of construction, drones and aerial photogrammetry have been implemented as a working tool to achieve higher levels of productivity in field information gathering processes in a faster, more accurate and economical way, in some cases.The purpose of the project developed in this book is to elaborate a 3D digital point cloud model of the Campus of the University of Sonora, Central Regional Unit, and compare it with one elaborated before the beginning of the COVID-19 pandemic, with the objective of determining if by means of these images it is possible to identify if there were or not affectations to the university infrastructure during that lapse.
