Embodiment Construction

[0028] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Hyperspectral imaging technology is developed on the basis of visible / near-infrared spectral analysis technology and machine vision technology, which perfectly combines spectral analysis technology and image processing technology. While obtaining the spatial information of the sample, the hyperspectral imaging technology also provides spectral information of hundreds to thousands of narrow bands for each pixel on each image, so that spectral data of any wavelength can generate an image, thus To achieve "map integration", the data it obtains is a high-dimensional data cube. The embodiment of the present invention provides a non-destructive detection method for comprehe...

Abstract

The invention relates to a nondestructive detection method for comprehensive character living bodies of plant seedlings, which comprises the following steps of: performing high-spectrum imaging on the plant seedlings, extracting RGB images and a spectrum of a specific area from a high-spectrum data cube, and acquiring morphological parameter, component content distribution and disease and insect pest information of the seedlings by image processing and spectrum analysis; and establishing a growth prediction model of the plant seedlings by adopting a character-level information fusion method and a fuzzy comprehensive judgment method. The method can realize comprehensive judgment on characters of appearance, nutritional component and disease and insect pest information of the seedlings, and overcome the error caused by un-uniformity during component measurement.

Description

technical field [0001] The invention relates to the technical field of spectral analysis and image processing, in particular to a method for non-destructive detection of comprehensive traits of plant seedlings in vivo. Background technique [0002] The process of plant seed germination to seedling growth is a complex physiological, biochemical and material metabolism process, which is regulated by its internal or external substances, and shows the effects of seed vigor, seedling growth, morphological characteristics, cell organization, and material metabolism. , directly or indirectly affect the vegetative growth and reproductive growth of crops, and then affect the final biological yield, economic yield, nutritional quality and safety. Therefore, many agronomists, breeders, and biochemists are very concerned about the growth characteristics of plant seedlings. Plant observation in the field focuses on population parameters, while seedling monitoring focuses more on individ...
