【摘要】 随着DSP技术、电子技术和网络传输技术的飞速发展,对基于DSP的视觉监控系统的软、硬件研究已成为当今监控领域的一个重要研究方向。本文依托河南省自然科学基金攻关项目“双目视觉监控系统研制”,分硬件和软件两个方面对基于DSP的视觉监控系统进行了探讨研究,主要包括:(一)DSP+FPGA的单目视觉监控系统的硬件设计视觉监控系统的实际应用对系统的实时性提出了越来越高的要求。针对此要求,从模块化设计思想的观点出发,设计了一种基于TMS320C6201 DSP和ACEX1K100 FPGA的单目视觉监控硬件系统。(二)双目视觉监控系统通道切换算法设计双目视觉监控系统应具有按照要求在各个监控现场自由切换的功能。针对此要求,设计了一种双通道视频软件切换算法,使得输出的双通道视频在一个监视器上实现单独和同时显示的自由切换,并在DM642开发平台上实现了这一功能。(三)基于DM642的网络视觉监控系统的研究与实现将现代计算机网络技术和传统的视觉监控系统相结合,实现远程视觉监控,这大大拓展了视觉监控系统的应用范围。本文深入细致地分析研究了JPEG图像压缩算法后,将DM642开发平台通过Ethernet和PC机相连,构成了远程视觉监控网络系统,并在此系统上实现了实时视频的压缩编码、解码以及网络传输功能。更多还原

【Abstract】 With the rapid development of DSP, electronic and network transmission technique, research on the hardware and software of visual surveillance system has become an important research topic in the surveillance field. More consideration on the design of hardware and software of DSP system is required according to complex real-time application. This thesis, taking the key scientific and technological project of Henan province“The development of the binocular vision surveillance system”as the research background, devotes main efforts to the research of the vision surveillance system based on DSP in the aspects both hardware and software, mainly including:1. Hardware system design of monocular visual surveillance system based on DSP and FPGAThe actual application has set higher and higher real time demands for the visual surveillance system. To meet such a demand, a monocular surveillance hardware system based on the combining TMS320C6201 DSP with ACEX1K100 FPGA is designed from the viewpoint of the module.2. Design of channel switch algorithm of binocular visual surveillance systemWith respect to the different demands in the different surveillance scene, binocular visual surveillance system should have the channel free switch function in actual application. To meet such a demand, a dual channel switch algorithm is designed, which has the function that each of the two images from the dual channel can be displayed alone or both of the two images can be displayed in a monitor. At the same time, the function has been implemented on the DM642 developing platform.3. Development of the network visual surveillance system based on DM642By combining the modern computer network technology with the traditional visual surveillance system, the remote visual surveillance can be realized, which extends the surveillance system application. After analyzing JPEG image compression working principle, a remote visual surveillance system is constructed by combining DM642 developing platform with PC through the Ethernet. At last, video coding, video decoding and network transmission are realized on the system in this thesis.更多还原
