摘要
嵌入式系统主要用于各种信号处理与控制,在图像处理方面的应用越来越广泛。近年来,嵌入式开发技术、网络技术和多媒体技术的发展使远程监控成为可能。目前嵌入式监控系统已经在社会生活的各个领域普遍应用。本课题是以电磁发射现场无线监控为背景设计的。以往采用的有线视频监控方式布线复杂,对场景的移动和监控距离也有一定的限制,针对这个问题,本文采用基于ARM的无线视频监控方案,并且加入保密算法,形成保密无线视频传输系统,达到了较好的监控效果,同时实现了保密通信。论文主要内容如下:
首先,在分析课题的研究背景及意义的前提下,对基于嵌入式图像传输系统的国内外发展现状及研究方向进行了综述,给出了本课题嵌入式图像传输系统的总体设计方案。
其次,给出了基于ARM9的无线视频监控系统的硬件设计。将视频监控系统分为了三个组成部分,分别确立了监控端、无线网络和客户端的设计方案。
再次,基于交叉耦合映象格子的混沌特性提出了一种新颖的图像加密方案,用Chebyshev映射提供交叉耦合映象格子的初值,并用所产生的时空混沌序列值对灰度图像和彩色图像进行迭代和置乱处理形成加密图像,通过解密算法得到相应的解密图像,仿真结果验证了算法的有效性和实用性。
最后,在硬件平台的基础上,给出了以ARM9为设计核心的软件设计,将加密方案应用于无线视频监控中,完成了视频图像采集传输程序的设计。本文取得了良好的无线保密视频监控效果,通过实验结果分析验证了设计方案的有效性和可行性。
Embedded systems could be used to process and control signals and have been widely used in image processing applications. In these years, the development of the embedded technology, network technology and multimedia technology makes it possible for remote monitoring. At present Embedded monitoring systems are generally used in all areas of our social life. This subject aims to design a scheme with the background of national defense scene monitoring, such as EML. Previous monitoring systems always use cable, it makes route complex, and there are some restriction in the moving of scene and the distance between monitoring. The paper adopts wireless monitoring scheme which based on ARM, and adds in the secure algorithm, so a secure wireless video transmission system is formed, At last we get a satisfactory result and realize the secure communication. The main contents of the paper are as follows:
First of all, under the premise of analysis research background and significance, the development and research of embedded image transmission system at home and broad are reviewed, and the overall design of the embedded image transmission system in this subject is given.
Second, the hardware design of this wireless video monitoring system based on ARM9 is given. Video monitoring system is divided into three components, the hardware design of monitoring side, wireless networks and client-side are established separately.
Again, we propose a new image encryption scheme based on the chaotic feature of cross CML(coupled map lattices), use chebyshev mapping to provide the initial value of cross CML and the generated spatiotemporal chaos sequences to encrypt source image by the process of iteration and permutation, and decrypt the image by the corresponding decryption algorithm. The simulation results indicate the effectiveness and superiority of this scheme.
Finally, under the background of hardware platform, we give the methods of software design which is designed with the core of ARM. The encryption scheme is used in wireless video monitoring, thus we complete the design of video image collection and transmission program. We access a good result with this wireless video security monitoring system, the result verify the effectiveness and feasibility of this design.
