Solution
The implementation of the Stream Analyze Platform utilized edge AI to transform the company’s quality control processes:
• Edge-Based AI Processing: By deploying the Stream Analyze Platform directly on the manufacturing floor through Raspberry Pi systems equipped with cameras and displays, real-time data processing was localized, minimizing latency and data transmission issues.
• Automated Neural Network Analysis: The platform utilized a neural network trained on product images to analyze each component in real-time, automatically comparing captured images against models of defect-free parts to identify any discrepancies.
• Dynamic Anomaly Detection Pipeline: Anomalies were detected through a systematic comparison of neural network outputs with actual images, followed by a sophisticated statistical analysis to validate any potential defects.
