Local Bundling of Disparity Maps for Improved Dense 3D Visual Reconstruction
… 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 is a …

Adaptive Learning Terrain Estimation for Unmanned Aerial Vehicle Applications
<p>For the past decade, terrain mapping research has focused on ground robots using occupancy grids and tree-like data structures, like Octomap and Quadtrees. Since flight vehicles have different constraints, ground-based terrain mapping research may not be directly applicable to the aerospace …

OTMS: A Novel Radar-Based Mapping System For Automotive Applications
… roadways. In this paper, we propose an on-board terrain mapping system (OTMS), which is an automotive radar-based system that extends the automotive safety goals to include mapping and vehicle-to-X communications. The proposed system utilizes a 94 GHz 3-dimensional (3D) pulsed radar to sense the …

Evaluating Interferometric Synthetic Aperture Radar Coherence for Coastal Geomorphological Changes
… interferogram from which surface displacement or terrain measurements are made. The similarities between both SAR signals is captured in the coherence and its magnitude is determined by the spatial separation between acquiring antennas and the changes (if any) to the physical characteristics of …

Sensor Fusion and Obstacle Avoidance for an Unmanned Ground Vehicle
… analyzes the development and implementation of terrain mapping, path planning and control algorithms on an unmanned ground vehicle. Data from GPS, IMU and LIDAR sensors are fused in order to compute and update a dense 3D point cloud that is used by an implicit terrain algorithm to provide …

Re-presenting Groote Schuur: Exploring phenomenological notions in architecture and landscape
… element strikes a specific relationship to the terrain, mapping the histories and topographic changes that have shaped the site. The richness and complexity of these devices comes from being essentially relevant to the site, as adjectives and maps describing its variations, measuring its slopes, …

Modeling, Approximation, and Control for a Class of Nonlinear Systems
… which could have potential applications in terrain mapping algorithms. The second topic delves into estimation and control of history dependent differential equations. This study is motivated by the increasing interest in estimation and control techniques for robotic systems whose governing …

3-D Point Cloud Generation from Rigid and Flexible Stereo Vision Systems
… become a concern. Deciding if an area of terrain has a level enough slope and a wide enough area to land a Vertical Take Off and Landing (VTOL) UAV or if an area of terrain is traversable by a ground robot is reliant on data gathered from sensors, such as cameras. 3-D models, which can be …

Sequential Motion Estimation and Refinement for Applications of Real-time Reconstruction from Stereo Vision
This paper presents a new approach to the feature-matching problem for 3D reconstruction by taking advantage of GPS and IMU data, along with a prior calibrated stereo camera system. It is expected that pose estimates and calibration can be used to increase feature matching speed and accuracy. Given …
