Nowadays, high speed cameras are used in the big physics experiments as part of the diagnostics as well as a part of the control system. However, some of these processes imply real-time image analysis, which is challenging taking into account that the throughput associated with the frame rate and resolution of this kind of cameras can reach up to 500 MB/s. The solution proposed in this paper is an image acquisition and real-time processing system for CameraLink compliant cameras. The main contribution of this work is the use of areaDetector[1] for the control of the system as well as image post-process and storage. areaDetector is a module for the Experimental Physics and Industrial Control System (EPICS)[2] that provides general purpose interfaces for image acquisition systems used by a wide range of cameras. The integration of acquisition and processing systems with EPICS enables them for being controlled in a distributed way, with the benefits of using a tool widely used in the big physics experiments. EPICS and areaDetector facilitate distributed image processing, ideal for complex algorithms or to apply multiple processing algorithms simultaneously. The acquisition and pre-processing of the image is done in a FlexRIO card, a device based on Field Programmable Gate Arrays (FPGA) using PXIe technology. The use of this kind of reconfigurable hardware allows the implementation of deterministic high performance algorithms for image processing achieving real-time requirements. As an added value, it has been proved the possibility of including an image hardware timestamping using a clock implemented in the FPGA and synchronized with the Precission Time Protocol version 2 (PTPv2) [3]. The proposed system is based on an already defined methodology which allows an easy implementation of data and image acquisition systems. The hardware and software elements used in the system are part of ITER catalog for the Fast Plant System Controllers in PXIe form factor[4, 5]. The system validation has been done using a CameraLink compliant framegrabber fed with images from databases of real nuclear fusion experiment.
