Surface Inspection
Advanced Defect Detection on Challenging Materials
Overview.ai cameras excel at identifying and classifying a wide array of surface defects, even on challenging materials and under difficult lighting conditions.
Key Applications
Metal Stamping Inspection
Our AI Vision System excels in detecting and classifying multiple defects in metal stamping in a single pass. It addresses challenges such as identifying subtle defects like small splits, partial splits, pre-splits, necking, and surface irregularities on shiny metal surfaces. Traditional systems often miss these due to high reflectivity and the subtlety of the defects. The system's advanced segmenter and powerful AI ensure robust defect detection, significantly outperforming manual inspection methods and maintaining high-quality stamped components.
Underbody Overspray Detection
For automotive OEMs, our cameras effectively address issues with underbody overspray, particularly around mounting holes, which can impact quality and cause delays. The system identifies four types of defects: white streaks, black streaks, mist, and splatter, even under low contrast and glare conditions. With minimal training, the tool comprehensively captures all defects within regions of interest, and can integrate Node-Red logic to share x-y coordinates for easy defect tracking and correction.
Bearing Minor Defect Detection
Overview AI provides solutions for manufacturers of industrial-scale bearings, who struggle to identify extremely minor defects such as chips, scratches, and scrapes. These defects can vary significantly in location, orientation, and size, making consistent detection challenging for existing systems. Our cameras quickly create impact across all three defect types, proving robust to orientation and size variations, and can customize the approach to highlight impacted areas for scrapes versus exact x-y coordinates for chips.
Film & Material Defect Detection
For major film manufacturers, our cameras address the challenge of detecting fleeting wrinkles and defects on costly, continuously spooled TV product rolls. These issues are complicated by imperfect lighting and glossy surfaces, and defects can occur anywhere and disappear as the film rolls. Overview AI developed a segmentation recipe to detect defects before they disappear, even under difficult lighting and material conditions, and provides custom Node-Red logic and a dashboard to support operators in identifying critical inspection results and mapping multiple images to a single roll.
Medical Electronics Contaminant Detection
Our cameras assist in meeting strict requirements for medical electronics by identifying extremely fine contaminants, such as loose hair strands, even with overlapping color palettes. This capability addresses issues that previously led to negative customer feedback and extensive manual inspection. Overview AI trained a segmentation recipe to pinpoint contaminants and their exact location, incorporating Node-Red logic to set clear length and area thresholds to prevent overkill.
