【摘要】：大幅面扫描仪作为一种常见的大型计算机输入设备，有着重要的市场和研究价值，追求高质量、高速度、高精度的扫描一直是它所追求的目标。本文通过介绍大幅面扫描仪的组成，并结合一些先进的技术，提出了一种可靠的高速大幅面扫描仪控制系统设计方案。在新的设计中，首先采用三层结构，，将耗时的数据处理放在嵌入式Linux层中进行，从而使得低配置的PC机也能够使用扫描仪进行扫描；其次采用高性能的GL847扫描控制器，为设计高质量、高速度的扫描仪打下了基础；再次引入并行的设计思想，使多路CCD控制器的扫描和图像数据的网络传输并行工作，从而弥补了长期以来采用串行扫描方式带来的速度低下的缺点。最后根据校正的理论，设计出一套适应该扫描仪系统的校正方法。实验证明，采用该设计方案的大幅面扫描仪在各项技术指标上都表现的比较理想。
[Abstract]:As a common large computer input equipment, large format scanner has important market value and research value. The goal of large format scanner is to pursue high quality, high speed and high precision scanning. By introducing the composition of large format scanner and combining some advanced technology, a reliable design scheme of high speed and large format scanner control system is presented in this paper. In the new design, a three-layer structure is adopted first, and the time-consuming data processing is carried out in the embedded Linux layer, so that the low-configuration PC can also use the scanner for scanning; secondly, the high performance GL847 scanning controller is used. It lays the foundation for the design of high quality and high speed scanner, and introduces the parallel design idea to make the scan of multi-channel CCD controller and the network transmission of image data parallel work. This makes up for the low speed caused by serial scanning for a long time. Finally, according to the correction theory, a set of calibration methods for the scanner system is designed. The experiment proves that the large format scanner with this design is ideal in every technical index.
