Abstract

In order to solve the problem of speed matching between image data output and acquisition, it is convenient to provide simple and flexible transmission for high-speed digital cameras and image acquisition cards. This paper proposes a video processing module based on CameraLink interface technology. By making full use of the internal resources of FPGA, the algorithm is executed efficiently. The system not only supports the clock 85MHz, but also the acquisition cache is not less than 64MB. Real-time acquisition and processing of CameraLink with image characteristics of 200Hz/50Hz(16bit/8bit); Moreover, it supports two channels of 50Hz(8bit/8bit×3) CameraLink image output, and realizes the video conversion from CameraLink signal to SDI signal. The functional correctness and performance stability of the video processing module based on CameraLink proposed in this paper are verified through function and pressure tests.
