Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementation examples described here are only used to explain the present invention, and are not intended to limit the invention.

[0025] A method for high-throughput determination of plant type based on image processing, wherein, the test plant material: select 5 rapeseed materials in the mature stage, cut off the stem section containing branches on the main stem of the rape plant, and the main stem Stem segments bearing siliques. Five individual plants were taken from each material for measurement.

[0026] The cut stems with branches and siliques are placed on the sample placement plate, and the images are taken with a high-speed camera or a digital SLR camera, and the images...

Abstract

Provided is a high-throughput plant type measurement method based on image processing. The method includes the steps that 1 branches on a plant main stem and stem sections with pods on the main stem are cut off from a mature plate, and the branches and the stem sections are bagged and numbered for standby application; 2 the obtained stem sections are placed on a sample containing plate, image shooting is conducted on the stem sections placed on the sample containing plate through a high-speed image shooting instrument or a digital single-lens reflex camera, and images are collected and stored in an image collection card; 3 image processing software is used for drawing path straight lines between the main stem and the branches and between the main stem and pod stalks, included angles between the labeled path straight lines serve as branching angles and pod insertion angles respectively, included angle data are input manually to form an Excel file, and the data are stored for later analysis and counting so as to obtain plant branching angles and pod insertion angles. The results of the branching angles and the pot insertion angles measured through the method are good in accuracy, low in error, high in stability and good in repeatability, and the standard deviation of the high-throughput plant type measurement method is much lower than that of a conventional field manual measurement method.

Description

technical field [0001] The invention relates to the field of digital agriculture, in particular to a method for measuring plant type with high throughput based on image processing. Background technique [0002] The plant type of a crop plant is an important agronomic trait, which is closely related to the planting method and yield of the crop. my country's agricultural production is in a period of transition from traditional manual labor to mechanized production, and mechanized operations have higher requirements for crop plant types. The ideal plant type can not only be suitable for mechanized production, but also make full use of resources such as light, hot water, fertilizer, etc., so that resources can be used efficiently to achieve the purpose of low consumption and high yield. Plant branching angle and silique angle are of great significance for establishing the ideal plant type of crops. However, under normal circumstances, it is difficult to directly use an angle r...
