摘要
介绍了Camera Link接口的工作原理及Camera Link协议的主要内容,阐述了Camera Link硬件接口电路的设计方案.接口电路为图像采集卡的前端部分,主要功能为低压差分信号(LVDS)至CMOS/TTL(LVCMOS/LVTTL)信号的转换,相机控制和图像采集卡与相机间的串行通信.系统以FPGA为主控制器,通过实验实现了上述功能,完成了Camera Link接口相机图像的采集和显示.
The principle of Camera Link interface and the protocol of Camera Link were introduced. The design idea of Camera Link interface circuit was presented. The interface circuit is the front part of image acquisition card, which makes a signal transformation from LVDS to CMOS/TTL and the serial communication between camera and image acquisition system. FPGA was taken as the main controller in the system. Those functions were finally realized in the experiment, completing the acquisition and display of images via the Camera Link interface.
