Problems solved by technology

[0003] Most of the traditional research on rice root system relies on manual work. The rice root system is dug out of the soil and washed, then measured to obtain some parameters such as the length, diameter and related biomass of the root system. This traditional method is very labor-intensive and labor-intensive. The cost is too high, and the efficiency is low, and it will also damage the rice root system. When the amount of data is large, manual measurement will cause large measurement errors due to the subjective consciousness of the measurement personnel. In addition, manual measurement is difficult to dynamically measure the rice root system during the entire growth period.

Abstract

The invention relates to a device and method suitable for agricultural scientific research workers who can simultaneously acquire three-dimensional morphological parameters of rice plants and rice root systems for non-destructive measurement in rice cultivation and genetic breeding research. The CT detection device of the present invention is mainly composed of 7 functional modules: a ray source, a flat panel detector, a load rotating table, a lifting module, a roller conveying line, a precision motion controller and a computer system; the present invention adopts the roller conveying line to The sample to be tested is transported from the planting area to the detection area, and the automatic positioning and rotation of the potted crops and the automatic lifting of the ray source flat-panel detector are realized through the precision motion controller, so as to obtain the visible light images of the aboveground plants and the underground root system at different angles and heights. The X-ray tomographic image is then used to obtain the 3D reconstruction data of the rice plant and root system through the motion restoration algorithm SFM and the cone beam FDK algorithm, and then the 3D model data of the whole rice plant is obtained through the fusion algorithm, and the traits are analyzed.

Description

technical field [0001] The invention belongs to the field of machine vision detection technology and digital agriculture, and in particular relates to a device and method for non-destructive measurement of three-dimensional properties of rice plants and roots. Background technique [0002] The rice root system plays a very important role in the growth of rice plants. The rice root system is not only an organ for rice plants to absorb water and nutrients, but also a place for the synthesis of various hormones and amino acids. Rice roots affect the ecological environment of plant soil microorganisms by secreting phytohormones, organic acids and other substances. Root related traits are closely related to yield, and the structure of the root system can affect the effective utilization of nutrient resources in the soil by the whole plant. The structure of the root system indirectly affects the yield of rice to a large extent, so the study of rice root phenotypes has very impor...
