Abstract
In order to achieve quantitative description and analysis of root architecture, a 3D vector model building method for plant root was proposed. Firstly, three data structures of root node, root branch and root system are designed. Secondly, according to the linear characteristic of root, the root skeleton points are extracted by the slice algorithm. Then, branch topological relations is established by using the path planning algorithm based on connectivity. Finally, the attribute parameters (radius, area, circumference, etc.) of the skeleton points are extracted by the method of branch slice. The results of the vector model are preserved in the three data structures of the root system, and the three-dimensional phenotypic detection of the root system is carried out using the model data. Through the analysis of the phenotypic test results, and compared with the manual measurement results, the verification of the proposed method of the feasibility and accuracy.
