Method for visualizing apple taste map information

The invention discloses a method for visualizing apple taste map information. The method comprises the following steps: S1, acquiring taste data of apple samples based on an electronic tongue; S2, acquiring and preprocessing data of the apple samples based on a hyperspectral technology; S3, selecting characteristic bands; S4, constructing an apple taste visualization model; and S5, after establishment of a GS-SVM model, inputting predicted spectral values in 10 bands based on points, obtaining and recording a taste prediction output value under each point of spectral value as K (i, j), converting the taste value into a corresponding actual color value, and visually representing apple taste information. The method provided by the invention combines advantages of the apple samples in hyperspectral single-point difference with an electronic tongue taste overall information detection technology to realize visualization of the apple taste map information. 本发明公开了种苹果味觉图谱信息可视化方法，包括如下步骤：S1、基于电子舌苹果样本味觉数据的获取；S2、基于高光谱技术苹
