AI-Powered Machine Vision for Dent, Scratch, Hole, and Painting Defect Detection
Large electrical control panel boxes—used across automotive plants, power distribution rooms, manufacturing units, and industrial automation systems—must meet strict quality standards before they are commissioned or delivered to customers. Any visual defect on the outer enclosure such as dents, scratches, cracks, uneven paint, rust spots, welding defects, or misaligned doors can compromise durability, weather resistance, safety, and brand perception.
Manual inspection of large panel boxes is labor-intensive, inconsistent, and prone to human oversight, especially when the enclosure size is large (20 to 20 feet.), surfaces are reflective, painted, or textured, and the production throughput is high.
Intelgic solves this problem with a fully automated machine vision and AI-based inspection system that detects surface anomalies with high precision, regardless of surface texture, color, or lighting variations.
Understanding Large Control Panel Outer Surface Inspection
Outer surface inspection focuses on identifying visible defects on the external structure of the panel box
- Dents
- Scratches
- Cracks and weld cracks
- Paint defects (shade variation, peeling, improper coating)
- Deformations
- Uneven edges
- Pinholes & surface pits
- Misalignment between doors
- Gaps and uniformity between doors or covers
- Rust / corrosion marks
- Logo or label placement errors
These issues often arise during sheet-metal fabrication, bending, welding, powder coating, transportation, or assembly. Without automation, inspecting large surfaces uniformly is extremely challenging.
Why Automated Outer Surface Inspection Is Essential
Large Surface Areas
Large electrical enclosures have big, flat, and curved surfaces. Manual inspection often misses micro-defects and inconsistently scans the whole surface.
Human Limitations
Surface defects like tiny scratches or micro dents become hard to detect under factory lighting, viewing angles, and fatigue.
High Customer Expectations
OEMs in automotive, rail, power, and industrial automation expect near-flawless finish for their panels.
Compliance & Safety
Any structural deformation or crack can lead to long-term issues in sealing, safety, or mounting stability.
Near-Zero Defects
Modern factories are moving toward automated QC, traceability, and standardized output.
