NBV-HRR: Next Best View Planning Network for Highly Reflective Region Restoration in Robotic 3-D Scanning
Bibliographic record
Abstract
Three-dimensional scanning of highly reflective surfaces is a challenge faced in industrial metrology. The high dynamic range (HDR) technique offers a solution by fusing images taken at various exposures. However, its effectiveness is limited in regions where reflectivity exceeds the camera's dynamic range. To address this issue, this article introduces a next best view (NBV) planning network for the restoration of highly reflective regions, named NBV-HRR. Unlike traditional NBV networks focused on complete shape reconstruction utilizing global features, NBV-HRR targets the restoration of localized regions lost due to reflection, utilizing both global and local features. To accurately evaluate each view, a cross-attention-based module is devised to fuse features of varying dimensions. For network training, a dataset containing 70 400 training samples was collected from over 1000 highly reflective industrial parts in both simulation and real scenes. Experimental results demonstrated that the proposed NBV-HRR network achieved an average restoration rate of 99.3% within three NBV predictions, significantly outperforming the HDR technique (83.7%).

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
