摘要
介绍了一种针对USB2.0高速线阵CCD图像采集的嵌入式实现方案,解决了系统的兼容性和小型化问题,使得这项技术能够在工业现场得到广泛的应用。在此基础上,给出了图象采集卡和图象采集终端的组成、图象采集和嵌入式硬件设计中需要注意的问题,以及图象采集卡软件、Linux下USB设备驱动、图象采集终端程序的设计与实现。通过试验数据,验证了嵌入式实现方案的可行性,使得设备小型化成为现实。该方案对现有的以PC机为主的图像采集系统进行了改进。
A scheme for implementation of high-speed linear CCD image sampling based on USB2.0 with embedded system is presented, problems associated with compatibility and miniaturization can be resolved, thus promoting the application of this technology to a wide fields in industry. Composition of image sampling card and image sampling terminal, some importance for designing the hardware of iamge sampling and embedded system , furthermore the designing and implementation of the software of image sampling card. USB drivers in Linux. the software of image sampling terminal are also given in this paper. By the examination data, the scheme of embedded system is feasibility, miniaturization is able to make ture. The scheme also improves on image sampling system based on PC with general adoption.
