Distributed Image Analysis from Digital Cameras at ELSA using the RabbitMQ Message Broker — •Michael Switka, Klaus Desch, Thomas Gereons, Dennis Proft, and Axel Spreitzer — Physikalisches Institut, Universität Bonn

For digital camera based imaging and image analysis a distributed data processing approach was implemented at the ELSA facility. We utilize the RabbitMQ message broker to share the high data throughput from image acquisition, processing, analysis, display and storage between different work stations to achieve an optimum efficiency of the involved hardware. Calibration of beam profile monitors using OpenCV machine vision algorithms allow us to perform qualitative beam photometry measurements. We describe the features and experience gained with the imaging system and present the architecture and applications, such as the programming and web interfaces for machine operators and developers.
