設計與實作應用於西瓜採集無人機系統之人工智慧電腦視覺系統

為了解決Stationary的問題，作者馬約瑟 這樣論述：

本文設計和實現了一種用於採集、導航和檢測西瓜的計算機視覺系統的,該系統使用無人駕駛飛機且無需人工干預。該系統實現了單板計算機Nvidia Jetson Nano和為圖像傳輸樣式(Pix2Pix)而創建的捲積神經網絡。這些元素整合在一起用於檢測,姿態估計和導航以達到目標。所有流程均由狀態機管理,該狀態機負責激活或停用在後台運行的不同流程步驟。ROS平台用於創建不同進程之間的數據交換。無人機使用稱為mavlink的標準化協議來將單板計算機與飛行計算機進行通信。ROS環境中的mavros用於解釋兩個元素之間的所有數據。無人機的目標是創建一個無監督的系統以快速便捷的方式處理繁重的任務,例如西瓜收穫。

用於檢測的神經網絡結構經設計可達到30幀FPS,可在配套計算機中滿足較高的可靠性,較低的內存使用以及快速判斷來滿足這三個條件,這些條件對於實現自主飛行是必不可少的。

應用HHT於水位自動資料檢核系統

為了解決Stationary的問題，作者蕭武賢 這樣論述：

臺灣地區河川水位變化頻繁，由於水位資料需要現地監測取得，但現地可能有各種狀況，如儀器故障、傳輸異常及人為疏失等干擾，皆會影響其數據真實性，因此原始資料必須先執行品管檢核程序，將異常且不合理數據過濾排除，以利提供於水文研究分析較準確之數據使用。本研究所建立之自動化檢核程序利用希爾伯特-黃轉換(Hilbert-Huang ransform, HHT)達到檢核之目標，此方法為黃鍔博士於2009年所提出之時頻分析法，將訊號進行拆解並且分析各自瞬時頻率與振幅能量之相互關係。首先使用整體經驗模態分解法(Ensemble Empirical Mode Decomposition, EEMD)進行拆解，瞭解

此訊號之組成要素因子，為有限個本質模態函數(Intrinsic Mode Functions, IMF)以及一個剩餘函數(residual)，為達到辨識出異常值特徵，因此需最大程度表現出水位變化之突波(spike)與異常值的IMF分量，故而僅選擇第一個IMF分量進行希爾博伯特轉換(Hilbert Transform, HT)，轉換後可取得其時間-振幅能量關係圖，觀察該分量之振幅起伏對應真實水位情況，可知道其異常值之振幅數值，當振幅數值越大就可能有異常值出現，反之則為趨向合理情況，藉由觀察各點之振幅數值大小，設定一閥值作為過濾異常值之判斷依據，將超過閥值的點位過濾並排除，而選定閥值大小能控制品管

檢核結果，故可調節不同閥值進一步左右篩選結果，以此達到自動化檢核水位資料之目的。本研究使用傳統人工品管檢核作為標準取得該閥值，利用此閥值完成自動化檢核之最終篩選依據。為降低人工檢核時之人為因子影響結果，故而選定以與人工品管檢核結果約95%相似，若較保守設定其閥值，可盡量避免破壞原始數據之真實物理意義，篩選結束後仍可使用人工檢查確保其數據正確。依據品管檢核的結果得知，可發現自動化檢核可篩選出幾乎全部的異常值，將人工觀察到之明顯突波異常值，能盡量過濾剃除，並且對篩選結果以線性內插進行資料補遺，讓水位資料以連續且完整狀態呈現。自動化檢核程序相比人工檢核程序，能縮短檢核時間且節省檢核人員精力，提供更為

穩定運作之水位品管檢核程序，亦可更為靈活地根據不同篩選需求調整過濾門檻。
