Abstract

fetched live from OpenAlex

Over the last few years, the Visual-Inertial navigation systems have attracted considerable attention mainly due to the higher accuracy that is promised by the so-called tightly-coupled scheme where visual and inertial data are integrated at a low level in a common estimation problem. However, the calibration parameters of the camera (e.g. intrinsic and extrinsic parameters) and of the inertial sensor (e.g. sensor's mounting mis-orientation) are often left to be calibrated offline that makes the developed navigation system far from an off-the-shelf product. In this work, an enhanced tightly-coupled Visual-Inertial navigation system, based on the Multi-State Constraint Kalman Filter scheme is proposed that includes the sensors' calibration parameters in the state list to be estimated along with the navigation states. Experimental results on the KITTI odometry dataset shows a considerable improvement in the odometry accuracy compared to the case where those values are obtained from the calibration file of the KITTI dataset.

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.
