烤烟波谱特性的分析与识别

Analysis and Identification on Spectrum Characteristic of Flue-cured Tobacco

用野外光谱辐射仪通过实地的测量,获取了临沭县的烤烟、玉米、水稻3种作物的地物反射光谱数据。着重对烤烟的生态学特性进行了波谱分析,选择了计算反射光谱红吸收峰净面积的方法来识别3种作物的地物波谱,取得了较好的效果。为进一步利用卫星遥感图像实现烤烟监测奠定了基础。

Many spectrum data including flue-cured tobacco, corn and rice and so on were obtained from Linshu County, by open-air Analytical Spectral Device through measurement on the spot. Spectrum of flue-cured tobacco was analyzed on ecological characteristics. A good performance was obtained to identify three kinds of vegetations by calculating the area of red absorption peak. The study provides a good foundation for tobacco monitoring by land sat remote sensing images.
