摘要
本研究以複合材料為例，進行可靠性評估之非破壞性檢測驗證，利用熱影像之熱傳導特性可針對複合材料檢視其內部的瑕疵。檢測方法為使用一加熱設備，瞬間加熱複合材料，以及一紅外線熱影像儀。觀測該複合材料所發出的紅外線熱影像，做為檢測複合材料之有瑕疵及正常區域。具有簡單、迅速、經濟，檢查位置較不受限制，並可達到立即檢視複合材料瑕疵狀況，可運用於複合材料結構安全之提升及檢查業務推動。本文並利用數位影像在全方位影像合成與處理的優勢，讓原本難以分析、測量的材料扭轉的現象，可以透過本方法與系統，更即時且更精確的得到結果，大幅的縮短了材料試驗的時間。再者，透過更具即時性的動態或靜態影像拍攝，可以更詳細的分析材料在扭轉時的每個轉動角度時或每個時段時，材料上面的標記的變化，且透過電腦化的快速計算就可即時結果。未來不但可以應用在材料試驗上，更可以用於負載監控，亦即透過監控材料表面的標記的變化，來警示材料可能已接近屈服點。

ABSTRACT
In this study, take composite materials as sample; evaluate the reliability of non-destructive testing and certification. Use the thermal imaging method to exam its internal defects by heat transfer characteristics of sandwich composite material. The detection method is to use an instantly heating device adding on a composite material, as well as infra-red thermal imaging apparatus. The infrared issued by the observation of the thermal imaging, from it can be identified by the detection of composite materials within the defects and normal area. With a simple, fast, economic, checking the location is less restricted and immediately review the composite defects can be achieved. Besides, it can be safety upgrading and checking business-driven applied to composites structural. On the other hand, this article and take advantage of digital imaging in Omni-directional image synthesis and processing of, was reversed by original material difficult to analyze, measure, you can try this method and system, more real-time and accurate results, significantly shortened testing time. Furthermore, through real-time dynamic or static images more shooting, more detailed analysis of the material in each of the torsion angles of rotation or when you each time, marked changes in the material above and through computerized fast calculation of real-time results. Not only on the material test can be applied in the future, but can be used for load monitoring, that is, through a change of control material marking on the surface of, warning may have been closer to the yield point of the material.

Keywords: sandwich structure,non-destructive inspection, thermal image, image analysis, full range image.
