摘要

降低建物能源消耗為現今重要政策之一，而建築物外殼之熱傳透率則為評估節能效率之關鍵指標。目前獲取此參數之方法多採用建物設計構造大樣圖計算，對於真實外殼熱傳效能並無實際檢測與評估。本研究將紅外線熱影像儀與可見光相機組成之雙像感測系統搭載於無人機作為資料收集平台，以嚴謹之輻射和幾何率定程序確保資料其品質足以作為後續熱傳效能分析以及整合三維空間資訊之用。此外，透過縮尺實驗驗證以熱紅外影像進行現地量測獲取建材熱傳透率的可行性，並將以上技術實地應用於建物外殼之分析。成果顯示，透過本研究所提出之方法可快速將兩種型態資料完成輻射與幾何改正，透過環境參數量測即可大範圍獲取建物外殼的熱傳透率，最後產製同時具有空間幾何資訊與熱傳透點雲資料。

Energy conservation is now considered an important issue in many countries. To evaluate the energy efficiency, the thermal transmittance of building envelops is typically used as a key indicator. In this study, a drone-based platform integrating an infrared (IR) and a visible light (RBG) image sensors was developed for acquiring the data. Both radiometric and geometric calibrations have been performed. Experimental results revealed that the thermal efficiency of building envelops can be readily evaluated based on the data collected by the proposed system. It gives a clear evidence that a reliable and cost-efficient solution for evaluating architectural designs for energy conservation has become available by employing the system developed in this study.
