The invention relates to a nondestructive identification method of ginseng based on angular hyperspectral information. The method includes: acquiring ginseng samples with year and origin information marked; The ginseng samples were photographed at different angles, and two sets of one-dimensional vector radiance data and two sets of multispectral image data were obtained. dimensional vector data; construct a neural network with four inputs, input two sets of VNIR hyperspectral reflectance one-dimensional vector data and two sets of multispectral image data, and use the year and origin data as labels to iteratively train the neural network, Obtain the trained neural network; use the trained neural network to perform non-destructive identification of the ginseng to be tested, and obtain the year and origin data of the ginseng to be tested. |
