【摘要】：随着互联网技术的大规模应用,红外传感器技术的进步以及计算机视觉和图像处理技术的发展,红外热成像视频监控技术也有了长足的发展。之前的研究是将采集的红外视频通过总线传递到主机上,这需要专门设计图像传输模块,同时对显示主机提出了较高的要求。这在使用过程中带来诸多的不便。本文提出将红外图像通过无线网络传输,并在安卓智能手机、平板上实时显示图像的方案和研究,将会红外视频设备带来智能化,便携化。课题的研究工作任务是设计能够将红外视频通过无线网络传输的红外成像系统,这通过FPGA板采集红外探测器信号并通过DSP主板网络传输信号实现。此外并编写Android应用程序在手机客户端用以接收及显示图像。研究的主要内容包括以下几个方面:(1)实现一个基于DSP+FPGA的视频监控服务器(DVS)的硬件设计包括绘制原理图以及设计PCB图,按照功能模块将系统划分为视频采集模块以及网络传输模块。其中FPGA主板负责视频采集,DSP主板负责网络传输。在这一步骤里,DSP,FPGA芯片与电源,时钟以及各种外设(网络,视频,I2C)以及存储模块(FLASH,SDRAM)相连,完成了视频监控服务器的硬件设计。(2)在电路板的基础上开发,使得系统可以采集红外图像的数据,软件在CCS开发环境下编写,以RF5架构为基础,由TCP/IP协议实现视频的传输,并通过网络输出发送至客户端。并编写PC客户端程序测试,是否能够达到网络视频输出。测试表明:红外图像能在PC端正常显示,这表明服务器端的设计满足设计要求。(3)编写安卓APP程序,利用TCP协议接收数据并使用Surfaceview控件显示视频,并从而将红外视频监控的应用扩展到安卓平台上。(4)对红外图像增强算法研究及测试其效果,并将其移植到Android平台。经过测试,系统功能正常,图像能够顺利在安卓设备上显示。本文实现了红外视频服务器的硬件设计,同时可以在安卓客户端显示红外图像,从而将红外热像仪的应用扩展到安卓平台。
[Abstract]:With the large-scale application of Internet technology, the progress of infrared sensor technology and the development of computer vision and image processing technology, infrared thermal imaging video surveillance technology has also made great progress. The previous research is to transfer the collected infrared video to the host computer through the bus, which needs to design the image transmission module specially, and put forward the higher request to the display host at the same time. This brings a lot of inconvenience in the process of use. In this paper, the scheme and research of transmitting infrared image through wireless network and displaying image in real time on Android smart phone and tablet will bring intelligence and portability to infrared video device. The task of the research is to design an infrared imaging system which can transmit infrared video through wireless network. The infrared detector signal is collected by FPGA board and transmitted through DSP motherboard network. In addition, the Android application is written to receive and display images in the mobile phone client. The main contents of this paper are as follows: 1) the hardware design of a video surveillance server based on DSP FPGA includes drawing schematic diagram and designing PCB diagram. According to the function module, the system is divided into video capture module and network transmission module. The FPGA motherboard is responsible for the video acquisition. In this step, the DSP FPGA chip is connected to the power supply, clock and various peripherals (network, video I2C) and memory module flash SDRAM. The hardware design of the video surveillance server is completed on the basis of the circuit board. The system can collect the infrared image data, the software is written in the CCS development environment, based on the RF5 architecture, the transmission of video is realized by the TCP/IP protocol, and sent to the client through the network output. And write PC client program test, whether can achieve network video output. The test results show that the infrared image can be displayed normally on the PC, which indicates that the design of the server can meet the design requirements. (3) the Android APP program is written, the data is received by the TCP protocol and the video is displayed using the Surfaceview control. Thus the application of infrared video surveillance is extended to Android platform, and the infrared image enhancement algorithm is researched and tested, and transplanted to Android platform. After testing, the system function is normal, the image can display smoothly on the Android device. In this paper, the hardware design of infrared video server is realized, and the infrared image can be displayed in Android client, so the application of infrared thermal imager can be extended to Android platform.
