Claim 13:
14. A method for generating synthetic imagery for training artificial intelligence models for security and screening applications, comprising:
building/assembling/storing a volumetric object library comprising firearms, explosives, incendiaries, narcotics, controlled substances, enclosures, vehicles, structures, animals, and human figures using a data management module that loads object data from a variety of 2D and 3D data as slices of real or virtual objects, surfaces, meshes, voxels, points, paths, lines, curves, 3D models, Computer-aided Design (CAD) files, or specified procedural geometries;
storing a material library to comprising a plurality of materials that may be virtually placed in interior volumes of items in said volumetric object library;
selecting one or more volumetric objects from the object library and selecting one or more materials from the materials library, virtually placing one or more said materials in said interior volumes of said volumetric objects, and generating a variety of scenes, wherein a scene management module packs or places objects into one or more enclosures randomly or using computerized instructions as part of a packing algorithm defined in a scene generation specification and wherein the scene management module is configured to use object layer data to alter material properties randomly or using specific algorithms;
loading and populating a scene from the volumetric objects in a scene file definition into an electromagnetic radiation simulation engine configured to handle the placement, orientation, sizing, motion, materials, and deformations from the scene file definition;
performing simulation of electromagnetic waves by the electromagnetic radiation simulation engine according to a supplied job configuration that details, wherein users may specify parameters regarding radiation energy, energy binning, frequency, amplitude, wavelength, propagation, absorption, reflection, and refraction of electromagnetic waves and particles with various bodies in a scene.
