Problems solved by technology

[0003] Ear is one of the main organs of maize, which plays an important physiological function, and its shape has significant differences among varieties. Therefore, the geometric modeling and digital design of maize ear are of great significance to the virtualization research of maize. However, At present, there is no mature method for corn ear geometric modeling and digital design. Traditional computer-aided design modeling methods and general modeling software tools are difficult to adapt to the construction of corn ear models for specific needs, and do not have crop physiological characteristics. , does not meet the agricultural knowledge background

Embodiment Construction

[0044] The method for virtual modeling of the three-dimensional shape of corn ears proposed by the present invention is described as follows in conjunction with the accompanying drawings and examples.

[0045] Such as figure 1 Shown, the flowchart of the method of the present invention, step S1 is to observe the morphological structure of corn ears, such as figure 2 A schematic diagram of the morphological structure of the ear of maize is shown. Determine the characteristic parameters of the three-dimensional shape of corn ears, such as ear length: 30cm, ear diameter: 10cm, ear stalk length: 14cm, ear stalk curvature: medium, number of ear pedicle nodes: 10, bract leaf coverage: medium, ear grains Number of rows: 12, number of grains per row: 40, arrangement of grains: straight, balding rate: 0.11, color of grains: yellow / orange.

[0046] Step S2 is to establish a three-dimensional morphological virtual model of corn ears according to the characteristic parameters, includin...

Abstract

The invention discloses a three-dimensional morphological virtual modeling method of corn silk. The method comprises the following steps: observing the morphological structure of core silk and determining characteristic parameters of three-dimensional morphological of corn silk; establishing a three-dimensional virtual morphological model according to the characteristic parameters, wherein respectively carrying out modeling on silk axis, cluster stalk, spike stalk, bract and kernel. The three-dimensional morphological virtual modeling method combines the modern computer graphics technology andthe modern algricultural science and production process, can realize three-dimensional display of silk on the computer for different corn varieties by setting model parameters, and has stronger realistic effect. The model has strong controllability and easy operation and can meet the requirements of digital design of the corn silk.
