| 摘 要： | 综合PCA、LDA和BPR提出了一种新的基于近红外光谱短波段的玉米品种鉴别方法.针对37个玉米品种的近红外光谱数据,以833nm作为起始波长,选取不同的截止波长,得到不同波段的数据,以此进行品种鉴别.实验结果表明:在833～1 087nm短波段,本文方法识别率达到97.60%,与全波段相比,波段范围缩小了84.71%,而识别率只下降2.16%. |

| Abstract: | A novel corn varieties discrimination method using short wave band of near-infrared spectra was combined PCA,LDA and BPR.The NIR spectra of 37 corn varieties was collected and extracted with different cut-off wavelength at the same start wavelength 833 nm,and then varieties discrimination was carried out.The results showed that in the 833~1 087 nm wave band,the highest correct rate reached 97.60%,decreased only by 2.16%,but with an 84.71% shortening rate in wave range compared with full band. |
