| 摘 要： | 对于地表高温目标而言,具有明显区别于常温地物的独特波谱特性,在短波红外波段（1.3μm～3.0μm）遥感影像上,高温目标像元的辐射能量值为反射与发射能量综合。通过研究高温地物反射和发射光谱特性,构建高温目标短波红外遥感识别定量参数,提出了基于ETM＋数据短波红外波段的归一化火点指数（NDFI）方法。实验结果表明,NDFI可探测传统热红外方法难以识别的小面积高温目标,经野外验证识别精度可达94%。

| Abstract: | High-temperature surface has special characteristics when compared with the normal temperature surface under general environment conditions.The energy value of pixel radiation of high temperature surface is the sum of the reflectance and emission energy in the SWIR band（1.3~3.0μm）.In this study,we focus on the reflectance and emission characteristics of high-temperature target,develop the SWIR spectrum to identify the quantitative parameters for high-temperature targets,and design a Normalized Differential Fire Index（NDFI）method for ETM＋ data.The result shows that NDFI can identify a small area of high-temperature targets that traditional methods failed to,with the identification precision as high as 94% in the real outdoor environment. |
