Automated defect detection

Automated defect detection uses cameras and AI to inspect products and surfaces for flaws, scratches, cracks, dents, missing parts, and contamination, in real time, with no manual checking. Ultralytics YOLO models detect, localize, and classify each defect in a single pass as parts move down the line.

It depends on the data, but recent peer-reviewed studies report 84-99% accuracy with YOLO models tuned to a specific task, for example 99.4% on fabric, 98.8% mAP on PCBs, and 98.2% on semiconductor wafers. The Ultralytics Platform supports active learning, so accuracy keeps climbing as new defect types appear.

Published 2024-2026 studies apply Ultralytics YOLO to steel and metal surfaces, printed circuit boards, semiconductor wafers, welds, textiles, solar panels, aluminum castings, ceramics, batteries, and pharmaceutical packaging, anywhere visual quality control matters.

Yes. Rule-based machine vision struggles with variable, subtle, or previously-unseen defects. Ultralytics YOLO26 learns from your own examples to recognize scratches, hairline cracks, white spots, and missing components across changing lighting and part variation, reaching 98%+ mAP on several published benchmarks.

Fast enough for the line. YOLO26 processes a frame in about 1.7 ms on a modern GPU; published inspection systems report 186 frames per second on fabric and 2.3 ms per weld.

Yes. Most inspection deployments run on-premises because production data is sensitive and factory networks are unreliable. Ultralytics YOLO26 exports to 19 formats, including TensorRT for NVIDIA Jetson, OpenVINO for Intel CPUs, and Hailo accelerators, so models run line-side with no internet connection required.

Less than you might expect. Published defect-detection models train on a few thousand labeled images, for example the bridge-crack study used a 4,029-image dataset. The Ultralytics Platform handles annotation and training, and pretrained YOLO weights mean you fine-tune rather than start from scratch.

Collect images of your good and defective parts, annotate them, and train, all in one place on the Ultralytics Platform. For production deployment, enterprise licensing covers commercial use and keeps your code and data private.
