Rice Leaves Model Based On The Measured Data

Plant visualization,(also known as virtual plant) refers to the study of individual plants or plant groups by means of virtual reality applications, implemented on a computer plant growth during the development of three-dimensional space reproduction, in order to facilitate quick access to plant growth and development of dynamic parameter data, to better help people understand the changes in plant growth and development of visualization results with a strong sense of realism and superior interactivity features. In this paper, based on the measured data, by modeling for rice-related knowledge and application in order to establish combing visual model of Rice Leaves. Specific research work carried out the following five areas:1. A field experiment to obtain the characteristic parameters of rice leaf growth, combined with effective data system data collation and experimental design.2. The establishment of a technical route and test experimental design, the growth trend of rice leaves and the ratio of length and width of the relationship between analysis and description.3. In-depth understanding of the structure and growth characteristics of rice, fractal theory in-depth exploration.4. Establishment of a model and the model rice leaves were detected. Using a quadratic curve model to establish rice veins, use B and H curve curve established rice leaf edge curve model, analyze mathematical models of rice leaf and root mean square deviation method by means of model checking.5. Implement the model visualization. In NURBS surface modeling method as the core, the use of VC ++ and OpenGL 3D visualization modeling of rice leaves on a computer.Through experimental research, whole rice morphology modeling has laid a good foundation, allows researchers to more quickly understand the physiological parameters of rice leaf, providing a reference for the modeling of leaves other areas. At the same time, through the growth cycle of crops for rapid simulation, reducing the cost of agricultural experiment, accelerate the whole process of research, saving precious manpower and resources. By combining the latest biotechnology, to better carry out the design and genetically modified plant crops. Meanwhile, crop yield forecasting, pest prevention, research dynamic collection of new species herein data parameters also has some significance.
