| 摘 要： | 为了更好地研究马铃薯光谱特性,对马铃薯植株的植叶面积进行了探究。采用Spectrocam多光谱相机对光以不同照射角度照射下的植叶面积进行数据采集,并运用软件对数据进行二值化处理和亮度处理。实验结果表明,在中心波长为750nm和800nm的通道下,计算出的马铃薯植叶面积差异不大,但是将两者的二值图与原图进行细节对比,中心波长为800nm的通道的二值图与原图较为吻合,所以中心波长为800nm的通道是计算马铃薯植叶面积的最优通道。

| Abstract: | In order to further understand spectral characteristics of potato,the potato plant leaf area has been studied.Spectrocam multispectral camera data collected under different angle of the light source,software is used to process binary data and luminance.The calculation results of a potato plant leaf area show plant leaf area has little difference for 750 nm and 800 nm center wavelength.However,when center wavelength is 800 nm binary images match well with the origin by details.Thus,it is the optimal channel for measurement. |
