Embodiment Construction

[0043] The parameter template-based virtual simulation modeling method for corn leaves proposed by the present invention is described as follows in conjunction with the accompanying drawings and embodiments.

[0044] like figure 1 As shown, step S1 establishes a parameterized template library of corn leaves by scanning real corn leaves, where the parameters are leaf length, leaf width, and leaf vein curves. Specifically, a typical maize leaf is selected as the template data source, and the FASTSCAN 3D laser scanner is used to scan the maize leaf to obtain the scattered point cloud model of the leaf template. The point cloud model is as follows: figure 2 Shown; According to the point cloud model, use the parameter surface interpolation method to establish the parameter surface model of the blade, calculate the control point group of the surface, preferably NURBS surface interpolation, select the point with the NURBS surface control point topology as the parameter surface inter...

Abstract

The invention discloses a parameter template-based corn leaf virtual simulation modeling method. The method comprises the following steps: establishing a parameterized template library for corn leaves by scanning real corn leaves, wherein parameters comprise leaf lengths, leaf widths and leaf vein curves; searching a parameter template matching characteristic parameters from the template library according to the characteristic parameters of a target modeling corn leaf, wherein the characteristic parameters comprise a target leaf length, a target leaf width and a target leaf vein curve; and modeling the target modeling corn leaf according to the matched parameter template by taking the characteristic parameters as constrains. The method of the invention effectively solves the problem of structural modeling which is not easy to be expressed parametrically on the corn leaves; and the established model has strong sense of reality, which can meet the requirement on a digitized design of corn leaves.
