SYSTEM AND METHOD FOR COLLECTING AND GEOREFERENCING 3D GEOMETRIC DATA ASSOCIATED WITH A GPS-DENIED ENVIRONMENT

A system for georeferencing three-dimensional (3D) geometric data associated with a global positioning system (GPS)-denied environment. The system includes an apparatus couplable to a mobile platform and a computing system communicably couplable with the apparatus. The apparatus includes a processing circuit and a range sensor and/or a camera. The computing system includes a 3D generator module configured to generate a digital 3D model of the GPS-denied environment based on data acquired by the range sensor and/or the camera, a 3D survey control generator module configured to identify a survey control point within the GPS-denied environment and generate a 3D digital anchor within the 3D model of the GPS-denied environment, a georeferencing module configured to apply one or more non-rigid transformations to the 3D model of the GPS-denied environment, and a second processing circuit communicably couplable with the 3D generator module, the 3D survey control generator module and the georeferencing module.
