Abstract
The capability of a mobile robot to negotiate corridors is essential for autonomous navigation in an indoor environment. An approach is proposed for determining the corridor line locations and the vanishing point in a corridor environment using a single camera, based on hypotheses generation/verification and a feedback control strategy. A corridor line is the intersection line between a wall and the floor, which is, the farthest lateral position the autonomous robot can safely navigate in a corridor. There have been numerous approaches described in the literature which detect corridor edges and vanishing point; however, no solution has been reported to detect true corridor line locations in the presence of many spurious linear features around the corridor line. The proposed method consists of low, medium, and high level processing stages which correspond to the extraction of features, the formation of hypotheses, and the verification of hypotheses using a feedback mechanism, respectively. The system has been tested on a large number of real corridor images captured by a moving robot in a corridor. The experimental results demonstrated the reliability and robustness of the approach with respect to different viewpoints, reflection variations and different illumination conditions

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
