Abstract
Unmanned Aerial Vehicles (UAVs) require an accurate estimate of their state. Computer vision provides a number of benefits over conventionally used sensors, such as the Global Positioning System (GPS) or a Motion Capture System (MCS), in order to achieve state estimation and localization relative to a scene. Our work uses the output of an existing Visual Simultaneous Localization and Mapping (VSLAM) system which provides a scaled position measurement. We propose an observer design to estimate vehicle position and linear velocity. The observer fuses an accelerometer measurement from an Inertial Measurement Unit (IMU) and VSLAM system output. The observer depends on an attitude estimate from an Attitude and Heading Reference System (AHRS). A change of coordinates is used to transform the system into a Linear Time-Varying (LTV) form. Using these coordinates we consider the observability of the Visual Inertial Simultaneous Localization and Mapping (VISLAM) problem. Two observer designs are proposed and their performance is validated in simulation and experiment.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
