Multi-ccd Scanner Data Collection System Develop Based On Linux

In this paper, the object of study is multi-CCD large format scanner designed by a company. This large format scanner makeup with multi-CCD components and it widely used in printing, mapping and other fields.Research with multi-CCD scanner's key technology, this thesis presents a multi-CCD scanner data collection structure based on Linux. This article discusses the multi LM9833 chip's USB driver design with LIBUSB on Linux system, collection system data transfer on network, multi-CCD LM9833 chips'control by embedded control panel, the collection and cutting of image data and solution of the image horizontal dislocation. Base on those discussed, programming content development and the final on-line debugging, we complete the multi-CCD scanner data collection structure based on Linux.
