摘　　要：目的:为了获取多光谱图像数据,实现对多光谱CCD相机图像信号进行显示、存储和回放,并以此为依据对相机的功能和成像质量进行检测,我们设计了一套多光谱CCD相机专用的图像采集系统。方法:系统硬件采用CPLD与FIFO相结合的方案对相机输出的数字图像数据进行整合和缓存,结合基于PCI总线的Camlink图像采集卡,使用Streams5图像采集软件,最终实现了多光谱图像数据的采集。结果:该系统四个通道可以同时同步采集四个谱段的多光谱数据,每个谱段图像宽度为3072个像素,10bit位宽。结论:该系统运行稳定,各项性能指标符合相机要求,已经应用于某多光谱相机的研制。Objective：A digital imageacquisiton system was designed for the multispectrum CCD camera. The system could test the function and performance of the camera by real time displaying ,recording and storing. Method：CPLD and FIFO were used for the pretreatment of image data. PCI based Camlink image recording card combined with Streams 5 recording software implemented the acquisition of large high speed image data.Result： the system could record 4 spectral iamge data at the same time ,and each channel cover 10 bit 3072 pixels .Conclusion： The system run steadily and the performance quietly meet the requirement of the camera. Then the system had been applied in the development of the multispectrum camera.
