Problems solved by technology

At the same time, some traditional spectral databases focus on browsing and querying spectral information, often through direct spectral matching or querying based on some general spectral features, which cannot meet the application requirements of the subdivided field of plant remote sensing monitoring from a functional point of view.

Embodiment Construction

[0095] The present invention will be further described below in conjunction with accompanying drawing.

[0096] A method for establishing a plant spectral library, such as figure 1 As shown, specifically:

[0097] Step 1: Get data

[0098] Plant Spectral Data Acquisition. In this study, the plant hyperspectral data measurement was carried out in accordance with the plant canopy hyperspectral measurement standard, from May to September 2017 in Hangzhou City, Zhejiang Province (Lon 120.34°, Lat 30.31°), selected multiple test points, and was conducted by ASD FieldSpec4 Pro FR (350nm~2500nm) spectrometer collects farmland plants including cowpea, soybean, sweet potato, peanut, amaranth, eggplant, sesame, citrus, peach, Youxian camellia, ginkgo, pomelo, loquat, tea tree, rice, wheat, etc. 16 Plants, a total of 450 spectra, plant canopy spectral curves and pictures such as image 3 .

[0099] Step 2: Spectral Feature Extraction

[0100] The features of ASD hyperspectral data ...

Abstract

The invention discloses a method for establishing a plant spectrum library. According to the invention, a standardized data acquisition method is adopted to collect data; a complete spectral feature extraction method, a complete feature sensitivity analysis method and a complete model building method are provided, plant classification and state monitoring are carried out, information redundancy inadjacent or similar wave bands can be effectively removed through a wave band self-adaptive clustering method, and the data use efficiency is effectively improved. Based on the method, a plant spectrum library is established, and a set of complete spectrum analysis and application method is provided for the plant spectrum library.

Description

technical field [0001] The invention relates to the establishment and application of a plant spectral library, specifically including a hyperspectral data collection method based on a plant spectral library, a feature extraction method based on hyperspectral data, a feature sensitivity analysis method and a classification algorithm research, and the establishment and realization of plant spectra and supporting A plant spectral library for applications such as information storage and query, plant classification and condition monitoring. Background technique [0002] Plant classification is very important for agricultural management such as agricultural planting area planning, nutritional regulation, and pest control; in ecology, we can understand the species, distribution, and community composition of plants, and indicate changes in the ecological environment. In landscaping design, plant species selection, planting distribution design etc. have very important application val...
