PCB Anomaly detection provides real-time anomaly detection in printed circuit boards (PCB) by running with AI-driven vision systems. It connects multiple video streams from different construction site cameras to AI-powered pipelines, all operating efficiently on a single industrial PC. This solution improves PCB production and compliance by anomalies before they can impact operations.
It is a cloud-native application composed of microservices, using pre-trained deep learning models for video analysis. This sample application offers the following:
- High-speed data exchange with low-latency compute.
- AI-assisted anomaly detection in PCBs.
- On-premise data processing for data privacy and efficient use of bandwidth.
To see the system requirements and other installation procedures, see the following guides:
You can read the overview of the architecture and logic of the application.
The components and services are as follows:
- DL Streamer Pipeline Server is a core component of the app. It receives video feed from multiple cameras (four by default, simulated with a video recording). With pre-trained deep learning models, it performs real-time object detection, classification, and tracking. It recognizes vehicles in the parking lot and sends their 2D bounding boxes to Node-Red, through the MQTT Broker. It also adds the detected bounding boxes on top of the video input, consumed by the WebRTC Server.
- Mosquitto MQTT Broker is a message distribution service, passing data between these sends the raw coordinates of detected vehicles to Node-RED. The feedback it receives is moved to Grafana to display.
- WebRTC Server serves video streams processed by the pipeline for end-user visualization. It is supplemented by the Coturn signaling server and passes the feed for display in Grafana.
It also consists of the following third-party microservices:
- Nginx is a high-performance web server and reverse proxy that provides TLS termination and unified HTTPS access.
- MediaMTX Server is a real-time media server and media proxy that allows publishing webrtc stream.
- Coturn Server is a media traffic NAT traversal server and a gateway.
- Open telemetry Collector is a set of receivers, exporters, processors, connectors for Open Telemetry.
- Prometheus is a systems and service monitoring system used for viewing Open Telemetry.
- Postgres is an object-relational database system that provides reliability and data integrity.
- Minio is a high performance object storage that is API compatible with Amazon S3 cloud storage service.
