Realtime state estimation for contact manipulation
… We propose a framework that combines tactile and visual sensing to improve the accuracy and robustness. Visual sensing is versatile and non-intrusive but suffers from occlusions and limited accuracy, especially with regard to tasks involving contact. Tactile sensing (including contact and force) …

Relative Pose Uncertainty Quantification Using Lie Group Variational Filtering
<p>The applications of visual sensing techniques have revolutionized the way autonomous systems perceive their environment on Earth. In space, the challenge of accurate perception has proven to be a difficult task. Due to adverse lighting conditions, high-noise images are common and degrade the …

Feasibility of active vision for inspection of continuous concrete pipes.
… hardware components of a prototype mobile remote visual sensing system have been designed and developed. The active vision system (AVS) operates within smooth-walled small-bore pipes (0.5m < d < 1.0m). The AVS consists of two distinct, but related hardware components, a controllable (pan and tilt) …

Bragg reflector geometries for colorimetric orientation and deformation sensing
… deployable, reliable, lightweight system that visually indicates potential alignment and structural integrity issues desirable. This thesis demonstrates the design of a system for visual deformation and orientation indication based on naturally occurring micro-scale surface geometries that show …

Development of Ground-Level Hyperspectral Image Datasets and Analysis Tools, and their use towards a Feature Selection based Sensor Design Method for Material Classification
Visual sensing in robotics, especially in the context of autonomous vehicles, has advanced quickly and many important contributions have been made in the areas of target classification. Typical to these studies is the use of the Red-Green-Blue (RGB) camera. Separately, in the field of remote …

Vision-based building energy diagnostics and retrofit analysis using 3D thermography and Building Information Modeling
… can take timely corrective actions. However, sensing what and where energy problems are emerging or are likely to emerge and then analyzing how the problems influence the energy consumption are not trivial tasks. The overarching goal of this dissertation focuses on understanding the gaps in …

Towards real-time light field processing for quantitative imaging and perception
… As a result, the adoption of SAPIV as a flow visualization technique was limited. Particle field reconstruction using LF or SA imaging succeeds by being able to systematically eliminate backscatter from illuminated particles in an experimental scene. A densely seeded PIV experiment can have a …

Machine Vision for Improved Human-Robot Cooperation in Adverse Underwater Conditions
Visually-guided underwater robots are deployed alongside human divers for cooperative exploration, inspection, and monitoring tasks in numerous shallow-water and coastal-water applications. The most essential capability of such companion robots is to visually interpret their surroundings and assist …
