多路同步CCD相机PCI数采卡的驱动编程

Device Driver Programming of Multi-PCI Data Acquisition Cards for Synchronous CCD Cameras

文章介绍了机载偏振CCD相机中3路同步PCI数据采集卡的系统结构和工作原理,着重讲述了Windows2000环境下多路PCI卡的驱动编程方法。针对机载高速数据的实时性要求,介绍了如何用DMA技术、多线程和双缓冲技术解决每秒24M字节的多CCD相机图像数据传输与存储。

Structure of data acquisition and record system of the airborne polarized CCD cameras were introduced. Put emphasis on method of driver programming of the MultiPCI data acquisition cards under Windows 2000 circumstance. For the realtime requirement of airborne and high speed data acquisition,it also presents how to using DMA,MultiThread and double buffers technologies to solve the problem of CCD cameras image data transfer and storage at 24MB/s.
