| 摘 要： | 为使可见/近红外漫透射光谱技术用于西瓜品质在线检测，自行设计加工了运动西瓜光谱采集系统，并进行了样品光谱采集。通过运动状态下西瓜光谱与品质指标的建模与预测结果，分析由于运动引起的噪声对光谱的影响，并分别采用最小二乘拟合法、Norris微分滤波等方法进行了光谱的平滑消噪处理，分析这些方法对光谱的平滑消噪效果及对建模与预测结果的影响，发现Norris微分滤波法更适合本系统采集到的西瓜光谱的平滑消噪处理，改善了光谱的平滑性，提高了建模与预测精度;建立了运动西瓜的可溶性固形物含量与可见/近红外光谱的相关关系模型，校正相关系数为0.895，均方根校正标准偏差RMSEC为0.549，均方根预测标准偏差RMSEP为0.760。

| Abstract: | To make Vis/NIR diffuse transmittance technique applied to quality prediction for watermelon in motion,the dynamic spectra detecting system was rebuilt.Spectra detecting experiments were conducted and the effects of noises caused by motion on spectra were analyzed.Then the least-square filtering method and Norris differential filtering method were adopted to eliminate the effects of noise on spectra smoothing,and statistical models between the spectra and soluble solids content were developed using partial ... |
