紅外線雙波段融合方法之研究 研究生：吳長洲 指導教授：劉宗平博士 元智大學電機工程研究所 摘要 紅外線的熱像系統(infrared thermal imaging system簡稱IRTIS)，依大氣的穿透效應，在大氣窗口3~5μm及8~12μm處，有良好的穿透率。而IRTIS的檢測器，期望在此兩大氣窗口，有很好的響應。所以，IRTIS的系統有這兩類的分別。然而在應用上，一般而言會依所使用的環境選擇適當波段的IRTIS。但是，對於軍事上的應用而言，單波段的TIS是無法滿足在複雜的背景環境下多目標物具有不同溫度下的偵測，因此就必需融合這兩個波段的訊息，加以運算，以提供給各種運用的需求。 在本文中，我們以加法、減法、乘法及除法作為影像融合的方法。另外，我們亦提出以擾動差向量及空間乘積的方法來做多目標辨識的紅外線搜索與追蹤(infrared searching and tracking簡稱 IRST)。從實驗的結果可知，對於IRST這是一個很有效的方法。

The Study of Infrared Dual Wave-band with Fusion Methods Student: Chang Zhou Wu Advisor：Dr. Chung Ping Liu Institute of Electrical EngineeringYUAN-ZE University Abstract The infrared thermal imaging system (IRTIS), based upon the effect of the atmospheric transmission, has extremely good transmittance in the atmospheric windows located at the band of 3~5 micron and 8~12 micron. There are two types of detectors that are used in the IRTIS in order to get good response in both windows. Usually, the choice of the waveband used in the highlight different IRTIS depends on our requirements in the applications. However, for the problem of military applications, the IRTIS designed with single band detectors is not enough to identify the multiple targets with very different temperatures simultaneously existed appeared in the complex backgrounds. Thus, we need to combine the images data come from dual wave-band for more applications. In this thesis, we firstly propose an approach with the diffusion method, including addition, subtraction, multiplication and division, of dual waveband images to improve the images data for applications. Secondary, we directly apply use the technique of the space gradient to recognize the multi-targets for infrared searching and tracking (IRST). The results show that the proposed method is very effective and suitable for IRST.
