Abstract

fetched live from OpenAlex

Vehicles must be able to localize themselves in all environments (unmapped and mapped) including urban and indoor areas where Global Navigation Satellite Systems (GNSS) performance may degrade. The research and development in this thesis cover three major localization techniques that use an assortment of sensors to achieve this. In urban environments, an Inertial Measurement Unit (IMU) and GNSS fusion using the Extended Kalman Filter (EKF) is developed. For indoor environments, Light Detection and Ranging (LiDAR) Simultaneous Localization and Mapping (SLAM) and Radio Detection and Ranging (radar) SLAM systems are devised. Novel techniques are developed to tune EKF parameters using a Genetic Algorithm (GA) approach and to apply radar in a Rao-Blackwellized particle filter. The thesis presents in-depth explanations of experimental approaches as well as results that demonstrate a variety of localization systems performing high accuracy estimations in several experiments.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
