Embodiment Construction

[0049] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0050] In the embodiment of the present invention, a method for virtual modeling of three-dimensional plant morphology based on radial basis functions, taking corn leaves as an example, specifically describes how to apply the method of the present invention to corn leaves, a plant organ. In addition to leaves, the modeling method described in the present invention can also be applied to plant organs such as stem nodes, fruits, ears, and tassels. In application, it is necessary to select the feature points of plant organs for modeling. The characteristic points of stem node, fruit, ear and tassel are selected on the central axis of the organ and distributed evenly. The modeling methods of plant organs such as stem nodes, fruits, ears, and tassels are the same as those of leaves, so they will ...

Abstract

The invention provides a radial basis function (RBF)-based plant three-dimensional configuration virtual modeling method, which comprises the following steps of: scanning plant image data by using three-dimensional laser; storing the data in a form of a triangular mesh; and realizing deformation of scanned data by using the radial basis function (RBF) by taking a framework topological structure and an organ topological structure of a specific plant as deformation restraints, thereby realizing construction of a target plant model. The sense of reality of details for plant organ three-dimensional configuration virtual modeling is greatly improved, and meanwhile, the method is easy and convenient and has higher efficiency.
