| 摘 要： | 以新疆红富士苹果为研究对象,初步探讨应用高光谱图像技术预测其重量的研究方法。首先采用高光谱成像仪采集苹果侧面和赤道面投影图像,提取苹果高光谱图像中前景与背景光谱偏差最大的波长图像（733 nm）,对其图像分割后获得目标区域的面积（像素数）特征。随后,采用不同的特征和建模方法,建立不同的重量预测模型,对比后确定最佳模型。结果表明,采用两个体积特征建立多元线性回归重量预测模型,苹果重量预测值与实际值间相关系数为0.9927,预测均方根误差为4.3393 g。

| Abstract: | The objective of this study was to investigate the prediction of the weight of Xinjiang Fuji apple by using hyperspectral imaging technology.Firstly,the images at the apple side and equatorial face were acquired by using hyperspectral imaging camara.The wavelength images(733 nm) with the largest spectral deviation between the background and foreground among apple hyperspectral images were acquired.The area features of objects were extracted after segmenting image.And then different prediction models were es... |
