一种桑葚花青素含量的光谱检测方法
摘要：
本发明公开了一种桑葚花青素含量的光谱检测方法。该方法包括以下步骤：a、采集桑葚样品的高光谱图像；b、采用化学分析方法测定桑葚样品的花青素含量参考值；c、提取桑葚高光谱图像中特征波长的信息为输入，以桑葚样品的花青素含量参考值为输出，建立模型；d、采集待测桑葚特征波长下的光谱图像，利用步骤c建立的模型计算待测桑葚的花青素含量；所述步骤c中的特征波长为985nm和1389nm。本发明方法实现了桑葚花青素含量的快速无损检测。
摘要（英）：

The invention discloses a method of spectrum detection of the anthocyanidin content in mulberry. The method comprises the steps of a, collecting a hyperspectral image of a mulberry sample; b, adopting a chemical analysis method to measure a reference value of the anthocyanidin content in the mulberry sample; c, extracting information of characteristic wavelengths in the hyperspectral image of the mulberry sample and using the extracted information as an input, using the reference value of the anthocyanidin content in the mulberry sample as an output, and establishing a model; d, collecting a spectral image under the characteristic wavelengths in the mulberry sample to be detected, and using the model established in the step c to measure the anthocyanidin content in the mulberry to be detected. In addition, the wavelengths in the step c are 985 nm and 1389 nm respectively. The method of spectrum detection of the anthocyanidin content in mulberry realizes fast and nondestructive detection of the anthocyanidin content in the mulberry.
