摘要

本研究發展熱影像建構技術，先針對熱影像建構原理作詳盡的敘述，包含輻射基礎原理、單雙色測溫法，更提出單位快門法等。
在實驗方面，分成兩個部份，先以光譜儀驗證理論方法之可行性與準確度外，更可以針對既有之影像擷取系統找出適合於工業環境下之軟硬體設定參數。再以可見光攝影機進行黑體爐與實場測驗，除了使用單位快門法，更利用綠色帶通濾片，達到單張影像內同時取得適當的R/G比值，並使用其影像建構熱影像，所建構之熱影像技術後續將做為燃燒製程控制或優化操作之重要資訊來源。
最後利用有限元素法對實場燃燒爐進行二維模擬，並與實場結果相互驗證，其溫度場分布結果與實驗吻合。

The present work develops a construction technology for determining the temperature field in a combustion furnace. The construction of the thermal imaging technology provides important information about temperature field in a combustion furnace leading to controlling and optimizing the combustion process. The theory of the thermal imaging including the basic principles of radiation, single-color thermometry, shutter method and some important considerations is firstly summarized..
The experiments are divided into two parts, The results of first part, by spectrometer, verify the feasibility and accuracy of the theory of the thermal imaging and find out the soft-hardware configuration parameters of image acquisition system in practice.
The second one, by visible camera, tests the blackbody, and achieves a proper ratio of R/G by a single image, with the aid of a filter, together with an appropriate shutter method in order to construct the thermal imaging. The temperature predication agress very well with themeasured temperature. In order to develop a simple simulation and prediction tool, a two-dimensional finite element model is employed to simulate the temperature field in a furnace. These results agree with those obtained in experiments.
