The Absolute Line Quadric and Camera Autocalibration

, 2004
We introduce a new geometrical object providing the same information as the absolute conic: the absolute line quadric (ALQ). After the introduction of the necessary exterior algebra and Grassmannian geometry tools, we analyze the Grassmannian of lines

Autocalibrating vision guided navigation of unmanned air vehicles via tactical monocular cameras in GPS denied environments

, 2018
This thesis presents a novel robotic navigation strategy by using a conventional tactical monocular camera, proving the feasibility of using a monocular camera as the sole proximity sensing, object avoidance, mapping, and path-planning mechanism to fly and navigate small to medium scale unmanned rotary-wing aircraft in an autonomous manner.
