Embodiment Construction

[0024] According to botanical research, there are a large number of scattering structures inside plant tissues, such as cell structures and various macromolecules. These scattering particles will produce various movements during plant metabolism, such as the slow movement of chlorophyll and starch molecules in the cytoplasm, and the Random motion of inorganic ions and macromolecules. Under the action of the movement of these scattering particles, the laser speckle intensity fluctuates. Considering the statistical characteristics of the random complex vector amplitude of the speckle, the first-order or second-order statistical characteristics are calculated by statistical analysis of the speckle image. Among them, the first-order statistics describe the fluctuation of the light intensity of a single point, and the second-order statistical characteristics calculate the spatial autocorrelation function of the speckle intensity distribution and its power spectral density, and make ...

Abstract

The invention relates to a method for monitoring plant growth process based on laser speckle technology, comprising the following steps: (1) plant speckle image acquisition and recording; (2) dynamicspeckle signal processing; (3) static speckle signal processing; (4) Image feature extraction; (5) establishment of an analytical model for the relationship between plant growth state and measured images and parameters: choose different kinds and different growth status of blade, which covers different color leaf blade growth status, as well as the budding leaves, mature leaves and withered leaves, wither, and according to the different location and plant diseases and insect pests position, classify blades, collect original speckle digital interference image respectively. After the image is extracted urgently, the leaf vascular density [rho] and the vascular connectivity [sigma] are obtained. Combined with the dynamic speckle intensity D and the static speckle intensity R, the measurementparameter set is constructed, and the neural network fitting classification model is established; (6) Plant growth state determination and evaluation.

Description

technical field [0001] The invention belongs to the field of laser measurement, and relates to a method for obtaining plant growth state by using a laser coherent measurement method. Background technique [0002] Plants are the biological resources most closely related to human beings. They have rich edible, medicinal and industrial values, and also play an important role in the regulation and protection of the earth's environment. Plant photosynthesis mainly occurs in leaves, and leaves are important organs for plant transpiration and nutrient delivery. Many diseases and insect pests that threaten plant growth mainly damage the structure and function of leaves and hinder plant growth. Therefore, monitoring the growth process of plant leaves is of great significance for mastering the law of plant growth, guiding production, and formulating high-yield, high-quality, high-efficiency and high-efficiency cultivation technical measures. [0003] At present, in the process of sci...
