Intermediate infrared spectrum and SVM-based antler cap type identification method

Abstract

The invention discloses an intermediate infrared spectrum and SVM-based antler cap type identification method, and relates to the technical field of antler cap identification. The method comprises the following steps: drying, crushing and flaking a sample, collecting a diffuse reflection spectrum, carrying out multiple data processing on the collected original spectrum, and classifying the sample by utilizing a K-S inspection method; secondly, performing high-dimensional data compression and main characteristic component extraction on the spectral data by adopting a normalization and principal component analysis dimensionality reduction method; and finally, establishing SVM (Support Vector Machine), ELM (Extreme Learning Machine) and RF (Radio Frequency) identification models of sika deer antler caps and red deer antler caps by taking the whole-section SMC spectrum after principal component analysis and the MSC spectrum after principal component analysis after obvious difference wave bands are selected as input variables. According to the method, efficient, accurate and lossless identification of sika deer antler caps and red deer antler caps is realized through the mid-infrared spectrum technology and a method for establishing a model through a support vector machine SVM, a random forest algorithm RF and an extreme learning machine ELM.

Description

technical field [0001] The invention belongs to the technical field of antler hat identification, in particular to a method for identifying antler hat types based on mid-infrared spectrum and SVM. Background technique [0002] The antler cap is the platform-shaped horn plate left on the head of the sika deer or red deer after picking antlers. It gradually ossifies. It can be used to treat sores, swelling and poison, blood stasis pain, consumptive tuberculosis and internal injuries, etc. It has obvious effects on various gland inflammations. With the domestic development of deer medicinal materials, antler hats have become popular in the market. Although both sika deer antler caps and red deer antler caps are deer medicinal materials stipulated by the state, the price and medicinal value of sika deer antler caps are higher than those of red deer antler caps, and the shape and internal molecular structure of the two are similar, resulting in the deer antler caps on the market...
