基于CameraLink标准的多路红外图像采集处理系统

摘要

Aiming at the requirement of image collection and processing for long wave linear 5 k ×6 detector device,a multipath,large data amount ,high-speed and real-time image collection and processing system was designed and implemented.Image collection interface is five routes parallel CameraLink protocol and image acquisition card choo-ses 3 Xcelera-CL_PX4 in DALSA.Firstly,five routes image data are collected,which the data of every route are 1024 ×8889 ×16bit.Then,the images are processed by joint,non-uniformity correction,histogram equalization.The experimental results demonstrate that the system is stable and reliable for multipath,high resolution and real-time processing system,and the system has been applied to NETD and MTF testing system.%针对长波线列5k ×6探测器组件的图像采集处理要求，设计并实现了一种多路、高速、大数据量的实时图像采集显示处理系统。图像采集接口为5路并行标准CameraLink协议，采集卡选用3块DALSA公司的Xcelera－CL＿PX4。实验中，采集5路每路1024×8889×16 bit大小的图像数据，进行图像的拼接、非均匀性校正、直方图均衡等处理。实验表明，对于这种多路、大分辨率图像的实时处理，该系统是稳定可靠的，并且已成功应用于某成像N E TD和MTF测试系统中。
