檢查與提醒：一種結合參與式和經驗抽樣法的收集帶註釋之連續性移動數據方法

為了解決Backup Camera的問題，作者張修齊 這樣論述：

收集帶標籤的連續性移動資訊需要使用者付出相當的精力來標記一系列的移動資訊。我們提出了一個新的方法：“檢查與提醒”（CAR），一種結合了參與性（PART）和情境觸發採樣（ESM）的混合方法。 “檢查與提醒”具有使用者控制的優勢，又能減輕使用者在記錄移動時的負擔。同時，它具有ESM的情境觸發機制作為輔助，以提醒用戶標記。我們對9位參與者進行了CAR的初步評估，他們收集並標記了他們在15個工作日內的移動資訊。根據結果，與PART和ESM相比，參與者使用CAR收集了大量的帶有註釋的移動資訊。此外，與使用ESM相比，使用CAR的參與者的註釋率更高。我們的結果表明，結合了手動和自動記錄的混合方法很有希望

。我們未來的研究方向，會驗證這些結果並衡量與更多參與者合規相關的更多指標。

資源受限環境下的無線視訊監控系統設計與實作

為了解決Backup Camera的問題，作者劉彥泰 這樣論述：

目前大多數的網路監控系統使用有線網路以及單存取點的無線網路傳輸架構，在資源受限的情況下有線網路可能無法順利將網路線部署至目的地，而單存取點無線網路則容易受到訊號覆蓋率不足以及遇到鏈路故障時無備援選項可使用的問題， 同時為了降低建置成本，攝影機使用資源需求較低但壓縮率不佳的 MJPEG 編碼方式，同時降低每秒畫面張數來傳輸視訊。本文中我們將提出一種透過無線網狀網路進行視訊傳遞的視訊監控系統，利用無線網狀網路特性，可以在不需網路線的情況下快速部署攝影機。為了確保監控視訊能夠流暢的傳送至監控中心，攝影機利用視訊的動作向量來控制視訊位元率來減少網路壓力。我們使用低成本且易於使用的 Raspberry

Pi，運用圖形處理器以即時的方式將攝影機的視訊編碼為 H.264，並利用H.264 編碼過程產生的運動向量來辨識畫面動態事件來適當的調整編碼器位元率取得品質與流量之間的平衡。結果顯示，使用 Raspberry Pi 圖形處理器進行 H.264視訊編碼，CPU每分鐘僅平均使用 7.5%，記憶體僅使用2.0%，iv使用運動向量動態調整編碼器位元率於 3Mbps~500Kbps 時，相較固定3Mbps 可以減少不需要的網路頻寬，並減緩鏈路壅塞現象，讓監控中心可以順利接收影像；當發生鏈路壅塞或中斷時，無線網狀網路的鏈路調整功能可以自動切換到其他線路，讓視訊監控中心可以更可靠的接收攝影機的視訊。
