Abstract
The registration of 3D points clouds is an important and challenging task in computer vision. In this paper we consider the problem of localizing a rover through 3D terrain registration in a natural environment. Two different local feature-based 3D terrain registration approaches are investigated: spin-image matching and point fingerprint matching. To overcome the huge memory storage problem of local features-based registration algorithms and improve the accuracy of the matching results, while reducing the computing time of the matching process, we developed an enhanced matching algorithm. The rover global localization scenario was conducted in the Mars Yard located at the Canadian Space Agency. The experimental results using natural environment data sensed by a high resolution and accurate 3D range sensor (LIDAR), demonstrate the effectiveness our enhanced matching algorithm

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
