Surface Defect Detection Model of Motor Commutator Based on Semantic Segmentation
Bibliographic record
Abstract
The surface defect detection of industrial parts is very important in industrial automation production, but there are problems with the small number of defect samples and the small-scale defect. To solve the above problems, this paper proposes a surface defect detection model of motor commutator based on semantic segmentation. The model is divided into two parts: segmentation network and classification network. First, the segmentation network uses an encoder-decoder to better capture small targets. The encoder uses an improved lightweight network MobileNet V3 as a feature extractor. Effectively learn the optimal features from a small number of samples, and improve the segmentation accuracy of the network. Then the classification network uses the segmentation results to make predictions, and the segmentation results provide interpretability for the prediction of the classification network. Experiments show that the proposed model has good generalization ability on a small number of samples, can effectively detect small-scale defect, and has high accuracy.

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.
