Design And Implementation Of Embedded Network Image Acquisition System

With the rapid progress of multi mediate technology and computer networks, the research and realization of image acquisition have been highlighted in embedded systems. Currently, using its powerful processing capability and overall interface to design the image acquisition card, the equipments of image acquisition system are mostly based on personal computer, and the application is very extensive. However, because of his huge size, high costs, in convenience. In many outdoor occasions, Personal computers are not suitable for the images acquisition, in such environment, the dedication to design of a portable image acquisition system became necessary for the market.In this thesis, the feasibility of realizing an embedded network image acquisition system is investigated, A scheme of embedded network image acquisition system based on Intel XScale IXP425 Processor is designed, including the design of hardware and software architecture , the configuration design of hardware platform and software platform, the design of management of web, the design of system function module. In the whole design the flexibility of image acquisition is considered sufficiently, so the whole system can be used as a general image acquisition platform. This platform can be used to realize any compressing algorithms or protocols. This system has an excellent expansibility and is easy to be developed secondly.At the end of this thesis , the testing of the entire embedded network image acquisition system is demonstrated. The experiments show that this system can reach those function required initially. And the results prove that the design is correct.
