【摘要】：近幾年，隨著移動互聯(lián)網(wǎng)和移動智能終端的高速發(fā)展，室內(nèi)定位方法的研究已經(jīng)成為一個多學(xué)科交叉的熱點前沿領(lǐng)域。它工作在特定的室內(nèi)空間區(qū)域下，通過無線通信以及其他相關(guān)技術(shù)，可以通過終端設(shè)備實時獲取用戶當(dāng)前的位置信息。國內(nèi)外研究人員已經(jīng)在該研究領(lǐng)域做了大量的工作，推動著室內(nèi)定位方法與系統(tǒng)的發(fā)展。本論文在對現(xiàn)有室內(nèi)定位方法進(jìn)行深入分析的基礎(chǔ)上，針對現(xiàn)有室內(nèi)定位方法的一些不足，同時結(jié)合目前移動智能終端的發(fā)展現(xiàn)狀，提出了一種只利用移動智能終端完成室內(nèi)定位的方法，并提供兩種不同的解決方案：(1)基于室外輔助的室內(nèi)定位方法：該定位方法利用人們普遍使用的移動智能終端，以室外移動智能終端的高精度GPS經(jīng)緯度坐標(biāo)為基準(zhǔn)，室內(nèi)移動智能終端通過無線通信手段與其通信獲得該坐標(biāo)和RSSI值，再結(jié)合其他的一些信息完成定位。(2)基于慣性導(dǎo)航的室內(nèi)定位方法：該定位方法將移動智能終端中內(nèi)置的加速度傳感器、陀螺儀和磁強傳感器等慣性傳感器的傳感數(shù)據(jù)融合起來完成室內(nèi)定位。本文還嘗試將以上的兩種方案結(jié)合在一起實現(xiàn)室內(nèi)定位，實現(xiàn)兩種方法的優(yōu)勢互補，以實現(xiàn)一種連續(xù)的、成本低和精度較高的室內(nèi)定位方法。本論文的具體研究內(nèi)容如下： (1)調(diào)研分析現(xiàn)有的室內(nèi)定位方法，指出現(xiàn)有的室內(nèi)定位方法存在的不足。 (2)針對現(xiàn)有室內(nèi)定位方法的一些不足和當(dāng)前移動智能終端的發(fā)展現(xiàn)狀，提出一種僅利用移動智能終端完成室內(nèi)定位的方法，以達(dá)到成本低、可大范圍推廣應(yīng)用以及不需要前期大量調(diào)研工作的目標(biāo)。 (3)在(2)中提出的方法的基礎(chǔ)上，提供了兩種不同的解決方案，，并選取現(xiàn)有的經(jīng)典算法或改進(jìn)現(xiàn)有的經(jīng)典算法運用于這兩種解決方案中。 (4)在Android移動平臺上實現(xiàn)以上兩種方案，并在教研樓內(nèi)部構(gòu)建實驗場地，采集數(shù)據(jù)，分析并驗證這兩種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.
