A system for creating a three dimensional model of an environment includes a LIDAR scanning system to scan an environment to provide an image of a scene of the scanned environment, a geo-locator to tag a plurality of points within the image with geo-reference points and a labeler to label features of interest within the image of the scene and to identify possible access paths within the three dimensional model of the environment from the features of interest potentially providing an access path for a target drone.

LIDAR site model to aid counter drone system

A system comprising includes a plurality of three dimensional line-scanner LIDAR sensors disposed to provide a set of fanned beams that travel from one horizon into the air to the other horizon arranged to provide a light fence to detect an object that breaks the light fence and a sensor processor connected to the plurality of three dimensional multi-beam line-scanner LIDAR sensors to establish a vector of travel and a velocity of the object that passes through the multi-beam light fence at the location of where the beams are broken.

A method, performed by a computer having a processor and system memory, for calibrating a tie height of a ballast profiling rail vehicle having a remote sensing system, includes traversing the rail vehicle along a first calibration section of railroad track at a calibration speed, detecting, using the remote sensing system, a plurality of height to tie measurements in the first calibration section, establishing a rolling median average of the height to tie measurements, and determining a calibration tie height relative to the rail vehicle based upon the rolling median average.
