Survey on Coverage Path Planning with Unmanned Aerial Vehicles

Tauã Cabreira, Lisane Brisolara, Paulo R. Ferreira Jr.
2019 Drones  
The surveyed coverage approaches are classified according to a classical taxonomy, such as no decomposition, exact cellular decomposition, and approximate cellular decomposition.  ...  We address simple geometric flight patterns and more complex grid-based solutions considering full and partial information about the area of interest.  ...  Thus, more sophisticated approaches based on approximate cellular decomposition have been proposed for coverage with UAVs.  ...
