Abstract

fetched live from OpenAlex

This paper proposes a method to eliminate dynamic feature points in robot motion estimation for visual-inertial odometry (VIO) via a geometric feature matching confidence checking procedure utilizing the inertial measurement unit (IMU) data. The IMU motion model expressed in the camera frame of reference is used to estimate the fundamental matrix in this procedure. Thereafter, the estimated fundamental matrix is used to calculate the distance of the matched features to the epipolar line. Similarly the same distance is calculated using the fundamental matrix that is obtained by visual structure from motion. Then the two distances are compared to produce a feature-matching confidence measure that is used to decide whether the matched features are static or dynamic. Finally, we provide odometry simulation test results based on a real world dataset to show the effectiveness of the proposed method.

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.
