Corn internode phenotypic parameter obtaining method and device

Abstract

The embodiment of the invention provides a corn internode phenotypic parameter acquisition method and device, and belongs to the technical field of agricultural informatization. The method comprises the steps of obtaining images of corn internodes under different visual angles, and constructing a three-dimensional grid model of the corn internodes based on the images; and based on the three-dimensional network model, obtaining corn internode phenotypic parameters. According to the method provided by the embodiment of the invention, the images of the corn internodes under different visual angles are obtained, and the three-dimensional grid model of the corn internodes is constructed based on the images. Based on the three-dimensional network model, orn internode phenotypic parameters are obtained. The orn internode phenotypic parameters can be automatically determined by combining the three-dimensional network model, so that the precision and the efficiency of the measurement structurecan be improved. In addition, the requirements of subsequent corn structure function analysis and genome-phenotypic group association analysis can be met.

Description

technical field [0001] The invention relates to the technical field of agricultural informatization, in particular to a method and a device for obtaining internode phenotypic parameters of maize. Background technique [0002] Corn is one of the most important food crops in my country, with great potential for increasing production. The morphological structure of maize node units is the basic unit of maize plants and canopies. High-throughput and accurate analysis of the morphological structure of maize internodes is of great significance for understanding the morphological construction of maize plant height and the response of maize morphology to the environment. However, since maize internodes are wrapped by leaf sheaths and leaves, it is impossible to directly and automatically measure the phenotypic parameters of maize internodes. Wherein, the phenotypic parameters may include length, diameter, length, circumference, etc. of maize internodes. In related technologies, th...

Problems solved by technology

[0003] Due to the low efficiency of manual measurement, and it is difficult to reflect the change of internode length diameter and circumference with internode length, and corn nodes and internodes are not regular cylinders, the internode length diameter obtained by the method based on monocular images can only reflect the current measurement The parameters of the angle of view, so the related technology has certain errors in measuring the long and short diameters and estimating the circumference
