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 ar
