Survey on Coverage Path Planning with Unmanned Aerial Vehicles
2019
Drones
Preserved Fulltext
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. ...
