Abstract

The invention discloses a method and apparatus for acquiring plant three-dimensional chlorophyll fluorescent image information, wherein the method comprises the steps of subjecting a plant to be measured to dark adaptive treatment, and acquiring, under induction of exciting light, the plant's chlorophyll fluorescent image and gray image information at different angles; pretreating the chlorophyll fluorescent image and gray image information, acquired at different angles, of the plant to be measured so as to obtain chlorophyll fluorescent image and gray image to be reconstructed; loading the chlorophyll fluorescent image and gray image to be reconstructed, reconstructing the chlorophyll fluorescent image and gray image of the plant to be measured, correcting the three-dimensional fluorescent image by using a three-dimensional gray image to obtain a final three-dimensional chlorophyll fluorescent image. By using the method and apparatus, a chlorophyll fluorescent image of a single leaf can be acquired, and heterogeneity of plant photosynthesis can be sensed in three-dimensional space sense.

Description

technical field [0001] The invention relates to the technical field of plant detection, in particular to a method and device for obtaining three-dimensional chlorophyll fluorescence image information of plants. Background technique [0002] The use of non-destructive testing technology to realize the detection of plant physiological state information has always been one of the research hotspots. At present, non-destructive testing technology mainly includes multi-spectral and hyperspectral imaging technology, infrared thermal imaging technology and chlorophyll fluorescence imaging technology. [0003] Multi-spectral and hyperspectral imaging technology is mainly to obtain the map information of the plant body, and distinguish plants in different growth states from the perspective of space and spectrum; infrared thermal imaging technology generates the temperature distribution map of the plant tissue surface by obtaining the temperature of the plant tissue surface, Analyzing...
