Abstract

See full text

A material detection system mountable to a ground vehicle. The material detection system includes a first range determination system (RDS) that includes a first electromagnetic radiation (EMR) emitter configured to emit first EMR behind the ground vehicle within a first field of view (FOV), a first EMR receiver that is configured to receive first EMR reflections, and a first RDS processing device configured to generate first RDS data that identifies distances to reflective surfaces based on the first EMR reflections. A processing device is coupled to the first range determination system and is configured to determine, based at least in part on the first RDS data, that material exists on the road. The processing device is also configured to determine a location of the material, and cause the location to be communicated to a computing device that maintains a map that identifies locations of material larger than a predetermined threshold.
