The AI Solution

Image Analysis

Tata Elxsi’s AI solution leverages advanced image analysis techniques to meticulously inspect components such as bearings and gears. By utilizing state-of-the-art algorithms, the system captures high-resolution images of each component, identifying even the smallest defects that might be missed by the human eye.

Automated Insights

The solution integrates powerful AI models like YOLO (You Only Look Once) and EfficientDet for real-time object detection and defect analysis. These models process the captured images swiftly, providing automated insights into the quality and integrity of each component. The AI can distinguish between different types of defects and assess their severity, ensuring that only components meeting the highest standards proceed further in the production line.

Custom Dashboard

A custom dashboard designed by Tata Elxsi presents these insights in a user-friendly interface. The dashboard allows quality control teams to monitor inspection results in real-time, review detailed reports, and track historical data for trend analysis. This centralized view simplifies decision-making and enables quick responses to any quality issues.
