【摘要】：随着科学技术的不断发展,家用型机器人被广泛应用于人们的日常生活中。与此同时,移动嵌入式视频采集设备以其方便、快捷的特性,成为视频采集的主流方式。近年来随着移动互联网的飞速发展,基于WIFI的定位技术以其部署成本低、定位精度高和易于扩展等优势,成为室内定位技术的研究热点。基于上述三种因素,本文设计一种基于WIFI定位的多移动机器人视频采集系统,其可主要用于室内的视频采集和安全防护中。整个系统通过对多个移动机器人定位以及多位置相关的视频联合显示,从而实现对所在区域完整的视频采集。基于上述应用需求,本论文设计的基于WIFI定位的多移动机器人视频采集系统,其能够使用多个移动机器人的摄像头采集待测区域的图像信息,并将这些视频数据通过WIFI无线通信方式发送到机器人控制端;机器人控制端可以实时显示多个移动机器人所采集的视频数据,并且可以通过按键实现对多个移动机器人的远程控制;另外,该系统还包括定位系统,其中定位技术采用基于WIFI信号强度的位置指纹匹配算法。与此同时,本文还针对WIFI位置指纹定位算法的不足设计改进方案,并将其用到了系统的定位模块中,以提高定位精度。该系统根据设计目标分成了三个模块:移动机器人、机器人控制台、WIFI定位系统。移动机器人总体采用Arduino控制板作为控制中心、WebCam摄像头作为采集设备、TP-Link WR703N路由器芯片作为通信模块;机器人控制台采用C#WinForm进行界面开发;WIFI定位系统采用Java语言开发,Mysql作为指纹数据库。这三个模块通过无线节点进行通信,紧密结合在一起共同组成了本文所要设计的系统。文章最后对系统的硬件和软件进行了整体测试,验证了机器人远程控制、视频图像采集、WIFI定位等功能,测试结果表明,达到了系统的设计目标和要求。
[Abstract]:With the development of science and technology, household robots are widely used in people's daily life. At the same time, mobile embedded video capture device has become the mainstream of video capture because of its convenient and fast characteristics. In recent years, with the rapid development of mobile Internet, WIFI based positioning technology has become the research hotspot of indoor positioning technology because of its advantages of low deployment cost, high positioning accuracy and easy to expand. Based on the above three factors, this paper designs a multi-mobile robot video acquisition system based on WIFI positioning, which can be mainly used in indoor video capture and security protection. The whole system realizes the complete video capture of the region by locating multiple mobile robots and displaying multi-position related video jointly. Based on the above application requirements, this paper designs a multi-mobile robot video acquisition system based on WIFI positioning, which can use multiple mobile robot cameras to collect the image information of the area to be tested. These video data are transmitted to the robot control terminal through WIFI wireless communication, which can display the video data collected by multiple mobile robots in real time. In addition, the system also includes a location system, in which the location technology adopts the position fingerprint matching algorithm based on the WIFI signal intensity. At the same time, this paper also designs an improved scheme for WIFI location fingerprint location algorithm, and applies it to the positioning module of the system to improve the positioning accuracy. The system is divided into three modules according to the design goal: mobile robot, robot console and WiFi positioning system. The mobile robot uses the Arduino control board as the control center and WebCam camera as the acquisition device TP-Link WR703N router chip as the communication module. The robot console uses C#WinForm to develop the interface of WiFi positioning system. Java language is used to develop MySQL as the fingerprint database. These three modules communicate through wireless nodes, and combine closely together to form the system designed in this paper. Finally, the hardware and software of the system are tested as a whole, and the functions of robot remote control, video image acquisition and WiFi positioning are verified. The test results show that the design objectives and requirements of the system are achieved.
