Application of a direct georeferencing method of drone images for smart farming
In smart farming, information collected by autonomous devices needs to be related to its exact field location, that is, georeferenced. In this work, we study the applicability and accuracy of a simplified direct georeferencing method of drone images for

Calibration and accuracy assessment in a direct georeferencing system for UAS photogrammetry [PDF]
Unmanned aerial systems (UASs) have been already proven to be useful in fields and disciplines such as agriculture, forestry, or environmental mapping, and they have also found application during natural and nuclear disasters. In many cases, the environment is inaccessible or dangerous for a human being, meaning that the widely used technique of aerial
