基於人臉辨識的自動化測溫點名系統
為了解決Django model filter 的問題,作者許曄律 這樣論述:
COVID-19在全球以極快的速度傳播,嚴重的疫情已對人類的生活模式產生重大影響,民眾須在盡量減少人與人之間接觸的情況下維持日常生活,這進一步增加了對「非接觸式系統」的需求。但在學校或補習班這種場所,須先確認身分才能讓學生進入課堂教室,這樣的流程一般多以人工方式進行,但這種方法除了效率低以外,也容易由於工作人員的疏失而產生冒名頂替、代為簽到的狀況,再加上疫情緣故需要量測體溫,大幅提升了點名執行者的工作負擔,進一步地降低了點名效率,同時也可能導致人群群聚於門口,對於疫情防控更加不利。因此本論文提出並實作了一個基於人臉辨識的自動化測溫點名系統。本論文提出的系統,於伺服器端實現了人臉辨識點名機制,
並於客戶端透過封裝與藍牙結合智慧型手機與感測器,完成點名測溫裝置,並利用智慧型手機的運算能力,在客戶端先為伺服器篩選可用影像。另外,亦實作了易於使用者管理資料與查看點名結果的網頁。根據實驗結果,證實我們提出的方法可有效提高點名測溫的效率,在人臉辨識上也具有穩定的高準確度,同時此人臉辨識系統亦可使用證件照作為註冊影像,有利於大規模註冊。
設計與實作門禁管理系統用於COVID-19防疫情境
為了解決Django model filter 的問題,作者施博翔 這樣論述:
由於新冠肺炎疫情期間的相關規定,管理單位勢必得對出入口的通行人員之健康狀態嚴格把關。然而,透過駐點人員管理的作業模式不僅增加管理方的人事成本,對於通行人員也造成些許不便。本研究的目的用於簡化疫情期間企業管理單位業務流程,對以往的門禁通行管理程序進行更新,針對疫情時下的市場需求提出一個新型的門禁管理資訊系統。本系統將辨識技術用於人員身分確認及口罩配戴檢測,同時以傳感器偵測人員體溫,並透過管理平台即時監控人員通行情況,用以提升疫情期間管理業務流程之效率。此外,本系統也針對人員的通行數據進行額外處理及分析,設計了一個社群連結距離的評估方式,目的是為了匡列可能帶有確診風險的通行人員,進一步提供疫情調
