摘　　要：在整个光子晶体光纤熔接机的实时控制系统中,三维对准是非常关键的一步,三维对准的前提就是要对光子晶体光纤(Photonic Crystal Fiber,PCF)截面进行图像截取。本文介绍了基于ARM920T的嵌入式Linux下利用USB摄像头采集PCF截面图像的硬件、软件设计过程,最终实现了在目标板上图像的采集和处理。In the whole Real-time Control System for Photonic Crystal Fiber Fusion Splicer, three-dimensional alignment isa very important step, the premise of three-dimensional alignment is to obtain the cross-section image of Photonic Crystal Fiber. Hardware and software of gathering image data via USB camera based on Linux and ARM920T is proposed in thispaper. Finally, we successfully get the image data and process the image on the target board.
