  Negative Obstacle Detection System
Back | Next

The negative obstacle challenge is inherently challenging. At long range, the viewing geometry is so poor that even “obvious” obstacles like a 24-inch diameter pot hole are barely visible.



NREC is developing a perception system to accurately detect negative obstacles in the path of an unmanned vehicle (UGV). 

Successful autonomous navigation requires detection not only of stationary and moving positive obstacles (guard rails, vehicles, people), but also the detection of negative obstacles (holes and ditches) at ranges that are nearly impossible for ladar and difficult for cameras.

Advanced Negative Obstacle Detection System testing includes different scenarios and takes place at different times, night and day.  The goal is to learn to learn to detect negative obstacles more certainly and at a greater distance so that the UGV can travel on safer and faster paths.
