Abstract

The invention discloses a crop biomass nondestructive testing image acquisition and processing device and a testing method and aims at providing the crop biomass nondestructive testing image acquisition and processing device which is low in manufacturing and use costs and the testing method which is simple and convenient. The crop biomass nondestructive testing image acquisition and processing device comprises two camera height adjusting devices, a background wall, a calibration board, a lifting adjusting device, a seedling placing platform, a test bed and an image data acquisition, processing and analysis system. The image data acquisition, processing and analysis system comprises two charge coupled device (CCD) digital cameras and a computer. The camera control module of the computer is used for acquiring, displaying and storing the acquired images; and statistical analysis of the data is conducted through a biomass prediction algorithm module to finally obtain a crop biomass prediction model. The crop biomass nondestructive testing image acquisition and processing device and the testing method are suitable for the nondestructive testing of fresh biomass or dry biomass of potted crops or the biomass tracking and measurement of a single crop in the entire growth period.

Description

technical field [0001] The present invention relates to a crop image acquisition and processing device, more specifically, relates to a crop biomass non-destructive detection image acquisition and processing device and detection method. Background technique [0002] In the process of scientific research related to crops, it is often involved to measure the fresh biomass and dry biomass of crops. Biomass is an important indicator of crop growth monitoring. The biomass of a single crop reflects the growth of individuals, and the biomass per unit area reflects the growth of crop groups. At present, the biomass measurement methods mainly include direct harvesting method, observation and estimation method, model simulation method and remote sensing inversion method. The direct harvesting method is a traditional method for measuring vegetation biomass. Although this method is accurate, it destroys vegetation and is often used to verify the accuracy of other methods; The results ...
