本文使用數位攝影機配合影像處理技術對振動台試驗之量測進行研究，透
過非接觸量測方式可將儀器本身對試驗的影響降至最低。近年來數位技術解析
度已足夠用來量測一般變位，搭配自動化程式進行讀點，可避免人工讀點導致
的誤差及節省時間。研究結果顯示本方法之量測距離不若傳統之位移計有其限
制，且不限於單一方向之量測，只要在試驗過程中拍攝，經處理後即可取代多
組位移計及加速度計，此外亦可進行邊坡角度之量測，因此利用本方法來進行
振動台動態量測會較傳統方法來得簡單且多樣化。本文亦對振動台試驗中之量
測結果與承受振動之壁體彎曲變形理論進行比較，結果尚稱一致。

A newly developed non-touch system accompanied by digital camera
technique and image processing in the present study can reduce the influence
of testing apparatus on experimental results. In recent years the precision
of digital technology has constantly risen and digital instruments
measure deformation well. This system run by an auto computer program,
can prevent reading errors originating from equipment operators and minimize
running time. The results reveal that the system can measure better
than conventional displacement gauges, and it has the advantage of replacing
multiple-gauges and can use various direction measurements. After
successfully applying the system slope measurement, further applications
of the system will be more versatile and simpler. The testing results in the
laboratory are in accordance with those of the flexural wall theory due to
cyclic loading.
