【摘要】：现代社会人们已经越来越离不开室外导航,以GPS为代表的卫星定位和导航给我们的出行带来了极大的便利。受限于信号遮挡和GPS的定位精度,GPS无法满足室内场景的高精度定位需求。基于室内定位与导航,我们可以追踪室内人员和货品的去向,可以开发出休闲益智的游戏,可以确保某些危险环境下工作人员的人身安全,等等。可以说室内定位技术对于提高人们的生活品质有着巨大的推动作用。因此,国内外研究人员对室内定位的研究一直很火热,也涌现出大量的室内定位技术方案。小到各个高校,大到诸如谷歌、诺基亚等著名公司,都在努力研究出实用的室内定位产品。本文最初的构想是结合VR设备获取玩家的坐标,根据该坐标来检测玩家的位置和运动状态。该应用场景对于定位的精度要求很高。在分析了国内外定位技术和定位方法的优缺点的基础上,本文选取了超声波和红外线技术作为定位方案,结合超声波和红外线器件的特点提出了本文所采用的的定位方案和具体定位算法。在室内实际环境中,对室内定位系统进行了安装和布置,对其进行了系统性的测试。本文给出了超声波与红外线室内定位系统方案,设计了定位系统硬件。根据定位算法和数据处理方法,编写了定位系统所需的软件和显示程序。在实验室内环境下对定位系统进行了合理布置安装,测试了系统的各项性能指标,对该超声波与红外线室内定位系统的误差来源进行了分析。为了提高系统的定位精度,根据误差来源采取了一些补偿措施。通过测试本定位系统,结果表明基于超声波和红外线的室内定位效果显著,其定位精度较理想。本文所述的定位系统解决了现有的一些难点与问题,在实际的室内场景进行了安装部署与反复测试,实现了对运动对象的轨迹追踪和室内定位,对今后室内定位的发展方向和具体实施具有一定的参考价值。
[Abstract]:In modern society, people are more and more inseparable from outdoor navigation. Satellite positioning and navigation, represented by GPS, bring great convenience to our travel. Limited by the signal occlusion and GPS positioning accuracy, GPS can not meet the high accuracy of indoor scene positioning requirements. Based on indoor positioning and navigation, we can track the whereabouts of indoor personnel and goods, can develop leisure puzzle games, can ensure the safety of workers in certain dangerous environments, and so on. It can be said that indoor positioning technology to improve people's quality of life has a huge role in promoting. Therefore, researchers at home and abroad have been very hot on indoor positioning, and a large number of indoor positioning technology programs have emerged. Colleges and universities, as well as famous companies such as Google and Nokia, are working on practical indoor positioning products. The initial idea of this paper is to obtain the coordinate of the player with the VR device, and to detect the position and motion state of the player according to the coordinate. The precision of this application scene is very high. On the basis of analyzing the advantages and disadvantages of domestic and foreign positioning technology and positioning methods, this paper selects ultrasonic and infrared technology as the positioning scheme. Combined with the characteristics of ultrasonic and infrared devices, this paper puts forward the location scheme and specific location algorithm. In the actual indoor environment, the indoor positioning system is installed and arranged, and it is systematically tested. In this paper, the scheme of ultrasonic and infrared indoor positioning system is presented, and the hardware of the system is designed. According to the localization algorithm and data processing method, the software and display program of the positioning system are written. In the laboratory environment, the positioning system was reasonably arranged and installed, the various performance indexes of the system were tested, and the error sources of the ultrasonic and infrared indoor positioning system were analyzed. In order to improve the positioning accuracy of the system, some compensation measures are taken according to the error source. By testing the positioning system, the results show that the indoor positioning effect based on ultrasonic and infrared is remarkable, and the positioning accuracy is ideal. The positioning system described in this paper has solved some difficulties and problems, has been installed and deployed in the actual indoor scene and repeatedly tested, and has realized the track tracking and indoor positioning of moving objects. It has certain reference value for the development direction and concrete implementation of indoor positioning in the future.
