THREE-DIMENSIONAL LIDAR-BASED CLEAR PATH DETECTION
First Claim
1. Method for detecting a clear path of travel for a vehicle, comprisinggenerating a datastream corresponding to a three-dimensional scan of a target area surrounding the vehicle from a vehicle LIDAR system;
- estimating a ground plane for a present vehicle location using the datastream corresponding to the three-dimensional scan of the target area surrounding the vehicle; and
comparing the datastream corresponding to the three-dimensional scan of the target area surrounding the vehicle with the estimated ground plane to detect a clear path of vehicle travel.

Abstract
A method for detecting a clear path of travel for a vehicle includes generating a datastream corresponding to a three-dimensional scan of a target area surrounding the vehicle from a vehicle LIDAR system, estimating a ground plane for a present vehicle location using the datastream corresponding to the three-dimensional scan of the target area surrounding the vehicle, and comparing the datastream corresponding to the three-dimensional scan of the target area surrounding the vehicle with the estimated ground plane to detect a clear path of vehicle travel.
