In modern manufacturing and the shift toward Smart Factories, quality control and assurance (QC/QA) play a vital role. However, manual inspection methods rely heavily on experienced operators, while traditional Deep Learning solutions require large amounts of defective samples along with complex calibration.
To meet the demand for automated quality inspection in manufacturing plants, ESTEC has partnered with Toshiba to offer and deploy the AI Visual Inspection (AIVI) solution in Vietnam. Powered by Non-Defect Learning, this solution enables model training based exclusively on standard (OK) product data, detecting surface anomalies without relying on large defect datasets. By combining Toshiba's AI technology with ESTEC's system integration capabilities and extensive deployment experience across various industrial sectors, the AIVI solution aims to enhance visual inspection efficiency and optimize quality control processes in smart plants.

1. Current Challenges in Visual Inspection
Manufacturing enterprises often face major obstacles:
- Time- and Data-Intensive Process: Requires collecting and labeling large volumes of both defective (NG) and good (OK) product images. In practice, defects are rare, making NG data collection prolonged and difficult.
- High Expertise Required: Demands specialized AI engineers to fine-tune parameters and detection thresholds.
- Integration and Footprint Obstacles: Bulky dedicated inspection equipment is hard to integrate into existing production lines, resulting in high maintenance and calibration costs.
2. Key Advantages of AI Visual Inspection (AIVI)
Non-Defect Learning Approach
Requires Only Good (OK) Product Data: The system learns exclusively from acceptable samples to build a standard baseline model, significantly shortening training time and accelerating deployment.
Automated Threshold Optimization – Reduced False Alarm Rate: The technology automatically identifies areas prone to false alarms and performs supplementary training to optimize detection thresholds—ensuring real defects are never missed while minimizing false positives.
Intuitive Interface – Ease of Operation
Visual Workflow: Model creation, parameter configuration, result checking, and accuracy verification are all managed visually directly on screen.
No AI Expertise Needed: On-site operators can easily manage the system without programming skills or complex AI knowledge.
Flexible Integration & Space-Saving Design
Cost-Effective Hardware Setup: No need for expensive dedicated equipment; the solution can be retrofitted using standard commercial cameras, lighting systems, and computing hardware.
Compact Footprint: Fits seamlessly into space-constrained areas without disrupting existing production lines or incurring specialized hardware maintenance costs.

3. Practical Applications
Weld Inspection (Automotive & Motorcycle Parts): Welds often exhibit slight variations in surface finish even among acceptable products. The solution provides accurate real-time assessment and timely alerts for corrective action, powerfully supporting junior or less-experienced staff.
Automated Visual Inspection: Replaces repetitive manual defect screening, reducing workload pressure, minimizing fatigue-induced errors, and comprehensively boosting productivity.
4. Business Benefits
Defect Reduction: Early detection of flaws directly on the production line.
Reduced Inspection Workload: Optimizes quality control human resources.
Enhanced Process Efficiency: Ensures stable accuracy and shortens inspection cycle times.
