Surface Defect Detection Systems
ThreeDots Surface Defect Detection Systems combine high-resolution line-scan and area-scan cameras with AI deep learning algorithms to inspect 100% of manufactured surfaces at full production line speed. Systems detect sub-millimetre scratches, dents, porosity, cracks, coating flaws, and color anomalies on metal, plastic, glass, and textile surfaces.
Engineered around your production requirement — Real-time optical surface flaw, scratch, crack, and color variance inspection using AI deep learning vision models.
