考量CSI相位偏移偵測與校正之室內定位演算法
為了解決Aoa wifi 的問題,作者林聖曄 這樣論述:
通道狀態資訊(Channel StateInformation, CSI)可用於室內定位,起到監視人們生活的作用。它使用Wi-Fi多通道訊號,不受光源、聲音干擾,並具備優異的角度、距離感測能力。本文研究中心頻率5.22GHz,頻寬20MHz,56子載波的CSI量測值。在9個不同位置,收集實驗室中57個位置傳送的CSI訊號。在本研究中,我們發現隨機π跳動問題,使得每根天線的相位可能出現±π偏移,這主要是硬件的鎖相環造成的。由於相位的不同,三根天線之間有四種可能的相位差組合。為了估計使用者的位置,我們把CSI量測值轉化為熱力圖作為深度學習網路模型的輸入,來解決本問題。為了克服多路徑效應,經由多訊
號分類(Multiple Signal Classification, MUSIC)計算出到達角(Angle of Arrival, AoA)與飛行時間(Time of Flight, ToF)的熱力圖。然而,由於ToF量測平台存在延時偏移,在本研究中,把熱力圖最大值對應的距離平移到信號強度(Received Signal Strength Indicator, RSSI)對應的距離,再以接入點(access point, AP)的位置為中心,朝向為AoA參考方向,把極坐標轉為直角坐標。由於每根天線可能有π相位偏移,三根天線之間有四種相位組合,所以每筆資料的Rx有四張熱力圖。本文以卷積神經網路
(Convolutional Neural Network, CNN)、殘差神經網路(Residual Neural Network, ResNet)等神經網絡組成的深度學習網路(Deep Learning based wireless localization, DLoc),用訓練出的模型對不同位置的預測準確度,來探究AP數量、相位校正等因素對深度學習效能的影響,並與深度卷積網路(Deep Neural Network, DNN)和SpotFi的方法在校正π相位偏移的效能上作對比。
融合WiFi訊號強度與人體姿態估計進行兩階段定位系統
為了解決Aoa wifi 的問題,作者鄭和軒 這樣論述:
由於近年來人們對於定位的重視,全球定位系統(Global Positioning System, GPS)已被廣泛使用於我們生活中的應用,卻礙於建築物的干擾訊號傳播導致GPS在室內定位並不準確,因此如何在室內達到高精度定位成為人們重視的研究議題,傳統的方法是以訊號強度為基礎如:藍牙、Wi-Fi、ZigBee,通過三邊測量估算裝置位置,然而,基於訊號的定位方法容易因為室內環境的多路徑干擾,導致環境中的訊號分佈變動性大,產生高定位誤差,而近年來深度學習的蓬勃發展使研究人員藉由成熟的影像辨識技術對行人進行位置估計與室內定位,卻無法得到設備資訊以識別人員身份,為此我們提出了一種基於Wi-Fi與影像的
高精度人員室內定位方法。室內定位系統分為兩階段定位,第一階段通過使用智慧型手機收集三台Wi-Fi基地台兩個頻段2.4GHz及5GHz的訊號接受強度,並以機器學習方法進行粗精度定位預測,接著在第二階段分析監視攝影機捕捉的人員畫面,並以姿態估計模型提取影像中行人們的腳點座標,再藉由直接線性轉換與線性回歸模型得到影像人員的位置,最後與第一階段的Wi-Fi定位位置進行匹配,完成可識別人員的室內定位系統。本研究採用的實驗場域具備多遮蔽物及訊號干擾,因此我們收集2.4GHz及5GHz兩個頻段的訊號接受強度,減少2.4GHz的訊號干擾以實現更高的Wi-Fi定位精度,Wi-Fi的平均定位誤差達1.4公尺,並分
析兩個頻段的定位表現。在影像定位方面我們則提出兩種用於影像中的行人腳點提取方法,並以機器學習模型減少因為鏡頭扭曲與直接線性轉換造成的誤差,結果表明我們改善後的腳點提取方法能夠降低50%的定位誤差,也指出通過機器學習模型預測的定位結果比僅以2D線性變換的誤差減少約0.4公尺,達到誤差0.4公尺的高精度室內定位。
