Computer Vision in Industrial Optical Inspections:

Why Tailor-Made Software Wins Over Off-the-Shelf Solutions

In the world of automated industrial production, optical inspections with computer vision systems are essential to ensure product quality, compliance, and reliability. In high-criticality sectors like automotive or energy storage, where even the slightest imperfection can affect safety, inspection accuracy becomes a competitive lever.

When choosing vision software, many companies rely on established industrial suites. However, more and more operators are turning to tailor-made solutions: custom-developed vision systems designed to meet the specific needs of the production process.

Industrial Suites vs. Tailor-Made Solutions

Aspect Off-the-Shelf Industrial Suite Tailor-Made Solution
Stability High, tested in regulated environments High, if developed on solid specifications
Flexibility Limited: standardized configuration Maximum: open and modular architecture
Product Adaptability Partial: requires compromises or external adjustments Total: built around actual geometry and defectology
Artificial Intelligence Available but often not very accessible or customizable Integrated and adapted to defect type and process logic
Maintenance Centralized, bound to the supplier Customizable based on SLAs and internal skills
Integration with Business Systems Limited or sold separately Complete, with direct interfaces to MES, ERP, or local DBs

Practical Case: Visual Inspection of Battery Housings

A company specializing in metal housings for lithium batteries compared two solutions for the optical inspection phase:

Option 1: Industrial Suite

  • Recognizes known defects (scratches, oval holes)
  • Parameters can only be modified via standard interface
  • Every product variation requires external technical support
  • Limited learning capability for new defects

Option 2: Tailor-Made System

  • Algorithms specifically designed on real process images
  • Internal user interface for quick modifications
  • Modular pipeline with rapid expandability
  • Structured output for the MES system
Operational Result:
- 30% reduction in false rejects
- Greater operator autonomy
- Adaptation to special batches in under 24 hours

Responsiveness to Change: A Competitive Advantage

Production lines are increasingly dynamic. Part geometries, materials, and acceptance criteria change constantly. A rigid suite often hinders adaptation. A custom solution, instead, allows for quick and controlled interventions without starting from scratch each time.

Whoever Controls the Logic, Controls the Process

A tailor-made software is not just a technical system: it's a strategic asset. It allows you to define rules that reflect the production reality, generate targeted reports, and evolve the system autonomously over time.

Conclusion

Tailor-made solutions represent a choice of autonomy, responsiveness, and precision. When product quality depends on the ability to detect specific defects and quickly adapt to changes, a custom-built system proves to be the most robust and sustainable choice.
