A wearable system that learns a kinematic model and finds structure in everyday manipulation by using absolute orientation sensors and a camera
… a kinematic model of the wearer via body-mounted absolute orientation sensors and a head-mounted camera. With Duo, we demonstrate the significant benefits of endowing a wearable system with the ability to sense the kinematic configuration of the wearer's body. We also show that a kinematic model …

Determining Feasibility of a Propulsionless Microsatellite Formation Flight Mission
… COTS magnetorquer boards to command satellite orientation, a scenario in which two 3U CubeSats are initially deployed from the ISS NanoRacks at an altitude of 400 km. They are then commanded to achieve a relative separation of 1 km and hold the spacing to demonstrate the capability of formation …

Relative orientation with limited control in close range Photogrammetry
… of control points as required for a conventional absolute orientation procedure. The thesis investigates the replacement of the traditional control network by a few control distances measured between well-defined artificial markers or natural feature points. The measured distances must then serve …

Mathematical Advancements in Geometric Algebra for 3D Registration Problems
… begins by applying 3D Euclidean CMs to the Absolute Orientation problem in 3D registration with known correspondences, demonstrating that the proposed solution offers a viable and efficient alternative to traditional LA methods. It then extends this approach to the Iterative Closest Point …

Manifold Optimization for Robotic Perception
… rotation averaging, which aims to estimate the absolute orientation, given a set of relative orientations that are in general incompatible. It stems from the fact that if the rotations containing nonconvex constraints were solved first, then the remaining problem involving structure and …

The Application and Analysis of Automated Triangulation of Video Imagery by Successive Relative Orientation
… of images using an automated approach. Automatic orientation of strips of video frame imagery would facilitate the construction of three dimensional models with less demand on a human operator for tedious measurement. Often one has no control points, so only relative orientation is possible. The …

Geo-referencing and mosaicing agricultural field images from a close-range sensing platform
… digital compass was used to provide the absolute orientation of the camera, which can be used to geo-reference a single image. The calibration of both camera and compass was introduced, and necessary parameters for geo-reference were estimated. Based on the angles, positions and optical …
