Abstract:

Aiming at characteristic of mass data of image out from high-frame camera,a high-speed real-time image acquisition and processing system based on CameraLink interface was designed and implemented.The FPGA chipset EP3CF484 accomplished image acquisition and image pro-processing,and the high performance DSP chipset TMS320DM642 accomplished more complex image processing.The design idea,hardware architecture,and functionality of the system were introduced,and then the design method for each functional module of the system was described.The experimental results demonstrate that the system can reach 500 frames per second for real-time image acquisition and processing.At the same time,the system can complete the video interface conversion from CameraLink signal to SDI (Serial Digital Interface) signal.

Key words: image processing, image acquisition, real-time processing, DSP, FPGA
