地震工程實驗影像量測之規劃與分析-以牛鬥橋、單柱搖擺及鋼浪腹板實驗為例

近年來，實驗影像量測開始廣泛地應用在地震工程實驗領域。不過在影像量測實驗中，常常會因為疏忽了實驗過程中的細節，導致拍攝的影像品質降低或資料不完整。品質不良或資料不完整的實驗影像所分析出來的數據將會有較大的誤差產生，甚至有可能使整個影像量實驗宣告失敗。因為缺乏一套詳細的實驗影像量測流程，導致實驗失誤的機率提高。本研究根據三個地震工程實驗影像量測之案例，規劃出一套詳細的影像量測標準實驗流程。此外，本研究利用線上文件設計一套測試資料填寫系統，此系統可以整合影像量測研究人員之測試資料並分享其資料。本研究流程大致可分為四大項。首項為實驗演練。演練的目的是為了從中發現錯誤及未考慮周全的地方。第二項是實驗的規劃。現地實驗的規劃包括場地的勘察在場勘以及人員、儀器的配置等規劃。第三項是範例實驗中，進行影像量測工作的過程。第四項是將實驗完的影像資料及實驗資料做出詳細的資料彙整，以方便分析及他人使用。

In recent years, experimental imaging techniques are widely used in earthquake engineering experimental measurements. However, the measurement results may be in poor quality or incomplete if details of measurement processes are not well done. A detailed procedure is required to improve the quality of image-based measurement tasks. This research took three earthquake engineering experimental measurement cases as examples, planned a set of detailed procedures of the measurement, and used Google Docs to design an information form. The form allows researchers to upload and share camera facility information. The first step is to rehearsal the experiment. The purpose of the rehearsal is to find out possible mistakes and what are not well considered. The second step is to survey the experimental field, which includes the survey of the experimental field and settings of personnel and equipment can be. The third step is to setup cameras firmly and take experimental photos. The fourth step is to synthesize experimental images and data methodically and build a database to facilitate analysis for others to use.
