Computer vision for industrial defect detection

I4.0 computer vision has gone a long way since the early 2000s but discriminating OK from NOK parts on the shop-floor is still a demanding task – Read along to learn about challenges and solutions.

Semantic image segmentation for defect detection and quality inspection

Semantic image segmentation identifies object boundaries on a per-pixel basis. One obvious application in manufacturing is the detection and size measurement of defects. Given stable imaging conditions and advanced pre- and post-processing tools a suitable neural architecture can detect minute defects also under difficult conditions – e.g.. on reflective, contaminated surfaces.<br /> With our TensorFlow-based d-vision library we have realized cloud-based and on-premises image segmentation solutions for different customers. We use a public dataset to discuss typical challenges, workflows, and performance KPIs.
