Navigation of Mobile Robots in Natural Environments: Using Sensor Fusion in Forestry
Jürgen Rossmann, Petra Krahwinkler, Christian Schlette
Navigation using GPS is a common strategy which cannot provide
the desired accuracy in forests. In the forestry of North Rhine-
Westphalia (Germany) algorithms are developed to delineate
single trees from remote sensing data. These generated tree maps
can be used to create a virtual testbed. Different kinds of sensor
data can be merged to form a “visual GPS” system which
improves accuracy for the navigation of autonomous vehicles in
the forest. Algorithms were developed, which provide localization
results accurate enough to allow navigation to a single tree. Full Text
