Abstract
Inaccurate sensor data, such as by caused by reflections, may skew ground profile estimations that identify a profile or plane associated with a surface, such as a roadway. Correcting a ground profile that was based on inaccurate sensor data may include determining a location at which a slope of the ground profile meets or exceeds a maximum slope, determining a line associated with the location and having a slope of a magnitude equal to the maximum slope, and using the line to determine a subset of sensor data points that lies outside a region defined by the line. The subset of sensor data points that lies outside the region may be excluded from the set of sensor data points used to generate ground profile(s) and a new ground profile may be determined using the set of sensor data points, less the subset of sensor data points.
