探讨玉米秸秆被玉米螟蛀入情况的有效检测方法. 以玉米秸秆为试验样本,通过高光谱采集系统采集玉米秸秆样本的高光谱图像,通过光谱反射率平均曲线确定有效光谱区域,对有效光谱区域进行主成分分析,找到最能代表玉米秸秆被玉米螟蛀入的PC图像,并对此方法检测结果进行验证.结果表明,对玉米秸秆特征光谱区域进行主成分分析变换,可以快速、准确地检测出玉米秸秆虫害情况.
探討玉米秸稈被玉米螟蛀入情況的有效檢測方法. 以玉米秸稈為試驗樣本,通過高光譜採集繫統採集玉米秸稈樣本的高光譜圖像,通過光譜反射率平均麯線確定有效光譜區域,對有效光譜區域進行主成分分析,找到最能代錶玉米秸稈被玉米螟蛀入的PC圖像,併對此方法檢測結果進行驗證.結果錶明,對玉米秸稈特徵光譜區域進行主成分分析變換,可以快速、準確地檢測齣玉米秸稈蟲害情況.

In order to find effective way to detect corn borer situation inside corn stalks. It used corn stalks as test samples, and collected hyperspectral images of corn stalks samples by hyperspectral collecting system, determined valid spectral region by spectral reflectance average curves, and analyzed main composition of valid spectral region, to find PC image which can obviously present corn borer intrusion inside corn stalks, and to verify the test result. The result showed that to analyze main composition of corn stalks spectral region can speedily and accurately detect insect damage situation of corn stalks.
