Techniques for using 3D Terrain Surface Measurements for Vehicular Simulations
… is the development of techniques for using 3D terrain surface measurements for vehicular simulations. Contributions are made to vehicle model parameter identification, terrain filtering, and application-dependent interpolation methods for 3D terrain surfaces. Modeling and simulation are used …

Local Bundling of Disparity Maps for Improved Dense 3D Visual Reconstruction
… method for improved resolution of stereoscopic 3D terrain mapping by local dense bundling of disparity maps. The Unmanned Systems Lab (USL) at Virginia Tech is designing an unmanned aerial vehicle (UAV) first-response system capable of 3D terrain mapping in the wake of a nuclear event. The UAV …

Improving the Quality of Terrain Measurement
… and tire models has raised the requirements for terrain measurement capabilities. Inaccuracies that were once tolerable for measurement of general terrain roughness are no longer acceptable for these new applications. The techniques in this work seek to improve the quality of terrain measurement …

Improved Methods for Gridding, Stochastic Modeling, and Compact Characterization of Terrain Surfaces
Accurate terrain models provide the chassis designer with a powerful tool to make informed design decisions early in the design process. During this stage, engineers are challenged with predicting vehicle loads through modeling and simulation. The accuracy of these simulation results depends not …

High Speed Navigation of UGVs in Rough Unknown Terrains
The traversal of rough a priori unknown terrain by an Unmanned Ground Vehicle (UGV) at high-speed requires the assessment of terrain in front of the vehicle as well as algorithms to select a speed based on the identified terrain. Current techniques are either susceptible to miss-classification, do …

Multi-scale representations of virtual 3D city models
Virtual 3D city and landscape models are the main subject investigated in this thesis. They digitally represent urban space and have many applications in different domains, e.g., simulation, cadastral management, and city planning. Visualization is an elementary component of these applications. …
