Surface Defect Detection: Scratch, Stain, Burr, Crack | EEK
How each defect family is imaged and judged: scratches, stains, colour difference, burrs and flash, cracks, holes, foreign matter, missing parts, wrinkles.
Stain Defect Visual Inspection
Stain defect visual inspection: for oil stains, water marks, fingerprints and process dirt on leather, fabric and foam surfaces, diffuse uniform illumination with grayscale/color difference comparison distinguishes natural texture from real stains, outputs OK/NG and marks positions.
View Inspection Highlights →Color Difference Defect Visual Inspection
Color difference defect visual inspection: for batch-to-batch color difference, splice color difference and uneven dyeing on leather, fabric and plastic part surfaces, colorimetric comparison is performed under a stable light source and white balance reference to define acceptable and non-conforming color difference.
View Inspection Highlights →Scratch Defect Visual Inspection
Scratch defect visual inspection: for linear scratches on surfaces such as metal, plastic, glass and coatings, low-angle light or stripe light highlights raised and recessed shadows, distinguishing machining marks from real scratches.
View Inspection Highlights →Damage and Hole Defect Visual Inspection
Damage and hole visual inspection: for punctures, perforations and missing material in film, non-woven fabric, foam and mesh fabric, transmitted backlight provides the highest contrast, distinguishing designed holes from real damage.
View Inspection Highlights →Crack Defect Visual Inspection
Crack defect visual inspection: for cracking, crazing and micro-cracks on the surfaces of composite materials, coatings, glass and metal parts, low-angle light or 3D height information forms a clear image, distinguishing parting lines from real cracks.
View Inspection Highlights →Fuzz and Yarn Breakage Defect Visual Inspection
Fuzz and yarn breakage visual inspection: for raising, fuzz and yarn breakage on knitted, woven and denim fabrics, diffuse light forms a clear image of fiber anomalies, distinguishing normal raising from real yarn breakage.
View Inspection Highlights →Skipped Stitch and Poor Stitching Visual Inspection
Skipped stitch and poor stitching visual inspection: for skipped stitches, loose threads and uneven stitch pitch in sewing, quilting and wrapping processes, diffuse light forms a clear image of stitch path direction, distinguishing designed stitch patterns from real skipped stitches.
View Inspection Highlights →Foreign Matter Defect Visual Inspection
Foreign matter defect visual inspection: for extraneous impurities, hair, metal chips and adherents on the surfaces of food, pharmaceutical, electronic and material products, diffuse light forms a clear contrast image, distinguishing material patterns from real foreign matter.
View Inspection Highlights →Wrinkle and Indentation Defect Visual Inspection
Wrinkle and indentation visual inspection: for fold wrinkles, compression indentations and temporary crease marks on soft materials such as leather, fabric and film, low-angle light forms a clear image of raised and recessed shadows, distinguishing design pleats from true indentations.
View Inspection Highlights →Out-of-Tolerance Dimension and Contour Abnormality Inspection
Out-of-tolerance dimension and contour anomaly inspection: for contour, hole diameter, spacing and form deviation of die-cut parts, film, stamped and machined parts, telecentric lenses and edge measurement are used to distinguish measurement error from true out-of-tolerance.
View Inspection Highlights →Burr and Flash Defect Visual Inspection
Burr and flash visual inspection: for excess material, overflow and burrs on the edges of injection-molded, die-cast, stamped and die-cut parts, low-angle light or 3D height information forms a clear image of edge anomalies, distinguishing material fuzz from true flash.
View Inspection Highlights →Missing Part and Extra Part Defect Visual Inspection
Missing and extra part visual inspection: for presence and count verification of parts on assemblies, modules and multi-part trays, template comparison by position number is used to distinguish overlapping occlusion from genuinely missing parts.

Inspection objects on the factory floor vary enormously; as long as the workpiece can be imaged clearly and "pass" and "fail" can be stated clearly, there is a chance of automating the judgement. Send us your workpiece for an actual test.
