【摘要】：近几年，随着移动互联网和移动智能终端的高速发展，室内定位方法的研究已经成为一个多学科交叉的热点前沿领域。它工作在特定的室内空间区域下，通过无线通信以及其他相关技术，可以通过终端设备实时获取用户当前的位置信息。国内外研究人员已经在该研究领域做了大量的工作，推动着室内定位方法与系统的发展。本论文在对现有室内定位方法进行深入分析的基础上，针对现有室内定位方法的一些不足，同时结合目前移动智能终端的发展现状，提出了一种只利用移动智能终端完成室内定位的方法，并提供两种不同的解决方案：(1)基于室外辅助的室内定位方法：该定位方法利用人们普遍使用的移动智能终端，以室外移动智能终端的高精度GPS经纬度坐标为基准，室内移动智能终端通过无线通信手段与其通信获得该坐标和RSSI值，再结合其他的一些信息完成定位。(2)基于惯性导航的室内定位方法：该定位方法将移动智能终端中内置的加速度传感器、陀螺仪和磁强传感器等惯性传感器的传感数据融合起来完成室内定位。本文还尝试将以上的两种方案结合在一起实现室内定位，实现两种方法的优势互补，以实现一种连续的、成本低和精度较高的室内定位方法。本论文的具体研究内容如下： (1)调研分析现有的室内定位方法，指出现有的室内定位方法存在的不足。 (2)针对现有室内定位方法的一些不足和当前移动智能终端的发展现状，提出一种仅利用移动智能终端完成室内定位的方法，以达到成本低、可大范围推广应用以及不需要前期大量调研工作的目标。 (3)在(2)中提出的方法的基础上，提供了两种不同的解决方案，，并选取现有的经典算法或改进现有的经典算法运用于这两种解决方案中。 (4)在Android移动平台上实现以上两种方案，并在教研楼内部构建实验场地，采集数据，分析并验证这两种方案的可行性和性能。
[Abstract]:In recent years, with the rapid development of mobile Internet and mobile intelligent terminal, the research of indoor positioning method has become a hot frontier field of interdisciplinary. It works in a specific indoor space area. Through wireless communication and other related technologies, the current location information of the user can be obtained in real time through the terminal equipment. Researchers at home and abroad have done a lot of work in this research field, promoting the development of indoor positioning methods and systems. Based on the in-depth analysis of the existing indoor positioning methods, this paper aims at some shortcomings of the existing indoor positioning methods, and combines the current development status of mobile intelligent terminals. This paper proposes a method to accomplish indoor positioning only by mobile intelligent terminal, and provides two different solutions: (1) Outdoor aided indoor positioning method: this positioning method uses mobile intelligent terminal which is widely used by people, and provides two different solutions: (1) Indoor positioning method based on outdoor assistant: this method uses mobile intelligent terminal which is widely used by people, Based on the high precision GPS longitude and latitude coordinates of the outdoor mobile intelligent terminal, the indoor mobile intelligent terminal obtains the coordinates and RSSI values by means of wireless communication. Combined with other information to complete the positioning. (2) Indoor positioning method based on inertial navigation: the positioning method will the acceleration sensor built into the mobile intelligent terminal, The sensing data of inertial sensors such as gyroscope and magnetic intensity sensor are integrated to complete indoor positioning. In order to realize a continuous, low cost and high precision indoor positioning method, this paper also tries to combine the above two schemes to realize indoor positioning, and realize the complementary advantages of the two methods in order to achieve a continuous, low-cost and high-precision indoor positioning method. The specific research contents of this paper are as follows: (1) the existing indoor positioning methods are investigated and analyzed, and the shortcomings of the existing indoor positioning methods are pointed out. (2) in view of some shortcomings of the existing indoor positioning methods and the present situation of the development of mobile intelligent terminals, a method of using only mobile intelligent terminals to complete indoor positioning is proposed in order to achieve low cost. It can be widely applied and does not need a large number of research work in the early stage of the goal. (3) on the basis of the method proposed in (2), two different solutions are provided, and the existing classical algorithms are selected or improved to be applied to these two solutions. (4) the above two schemes are implemented on Android mobile platform, and the experimental site is constructed in the teaching and research building, the data are collected, and the feasibility and performance of the two schemes are analyzed and verified.
