  • 國內橋梁建設多為鋼筋混凝土結構,經年累月的交通負荷早已對橋梁造成程度可觀的損傷。近年來橋梁生命週期在營運與維護階段日益備受重視,除了社會對橋梁維護意識的提升之外,民眾對老舊橋梁的安全疑慮也因各種天災而浮上檯面。因此在橋梁建設已幾近飽和的情況下,橋梁檢測的需求迫在眉睫。但受限於台灣公路橋梁數量繁多,因此國內在這方面大多選擇執行上較為簡單的橋梁D.E.R.&U.目視檢測法。

    針對D.E.R.&U.目視檢測法,因為在人員流動的不可預測性以及檢測結果在評斷上的主觀性,造成不同人員檢測水準參差不齊,需藉由教育訓練提升橋檢人員檢測水準同時,然而現今橋梁檢測教育訓練課程僅僅介紹規範內容以及劣化樣態照片呈現,以2D的平面照片呈現沒有辦法了解各個視角下觀察劣化樣態的情況,且課程形式傳統且枯燥,冗長的課程時間容易導致學員的專注力下降,且在沒有實際「看過」現場的情況下,學員無法僅以文字的敘述體會劣化樣態破壞程度的差異性。

    因此本研究,藉由擴增實境技術,開發橋梁檢測AR輔助應用程式搭配橋梁D.E.R.&U.目視檢測法供學員體驗使用。本研究蒐集不同等級之裂縫劣化樣態製作虛擬裂縫模型,藉由Google ARCore檢測平面技術,讓手機識別裂縫平面並在上面建立特徵錨點,藉此讓虛擬模型貼在真實裂縫案例旁輔以比對,檢測人員在判斷上能有個參考範例,而非純粹藉以經驗判斷。本研究期許藉由教育訓練的過程讓學員體驗AR技術帶來有別於傳統教學的感官衝擊並藉此提升課程趣味性,增加課程彈性與互動性,提高學員專注力與學習表現。


    The Increasing flow of traffic has led to severe damages to bridges. Meanwhile, the gradually higher awareness of bridge maintenance in society, the public concern about the problems of old bridges have been highlighted after several natural disasters. Under the situation of bridge construction is becoming increasingly saturated. Hence, the more demand for bridge inspection is imperative. Considering the efficiency of bridges inspection, the D.E.R.&U. Visual Inspection is the most common way to apply.

    For D.E.R.&U. Visual Inspection, the employee turnover is unpredictable, and rating results are subjective. Therefore, it is necessary to organize educational training to promote the proficiency of employees in bridge inspection. However, the general courses of educational training only introduce specification content and some deterioration photos to students in the class, which leads to students’ low concentration and confusion about the differences in the degree of deterioration without seeing the real scene.

    Therefore, to improve inspectors to achieve their skill to the same level as much as possible, this study developed the mobile application of bridge inspection, which based on AR technology, which is provided for students to use with a visual inspection. Through the technique of plane identification, which is from Google ARCore, the virtual model would be stuck to the surface beside the “real crack”, which provides a reference example for staff in judgment rather than totally in empirical observation. In summary, the process of educational training enables students to experience New Tech and rely on this innovation. It will be more interesting, highly interactive, and effortlessly appealing to students.
