Comprehensive Direct Georeferencing of Aerial Images for Unmanned Aerial Systems Applications [PDF]
Optical image sensors are the most common remote sensing data acquisition devices present in Unmanned Aerial Systems (UAS). In this context, assigning a location in a geographic frame of reference to the acquired image is a necessary task in the majority
