Data structure of corn scene visualization

This research focuses on the study of crop scene visualization based on crop simulation and knowledge engineering techniques. Corn data are measured in the field of Luancheng, Mebei Province and Shunyi, Beijing City. In the study of 3D simulation of crop realistic structure, the object-oriented knowledge Database of crop realistic structure is in further development. The data structure of realistic scene used here can organize the whole visualization process well. With the appearance of the realistic structure model of the quantity remote sensing, the field of crop visualization study is more and more important. During the process of studying visualization, the object-oriented 3D visualization data model arises, which is used as the formation of the crop realistic structure. 3D visualization data model can be applied to the description of crop structure successfully by object-oriented design and confirming the geometrical and logical relation. In this paper, we have the description and computer simulation of the scene of vegetation as a main clue. We are working on the data organization by design principle of Objected-Oriented DBMS. We use the corn scene data from the experiments in Shunyi, Beijing City, 2001 as an example to build the remote sensing data model. Then, we produce the 3D model using L-system, and present 3D scene of summer corn on the computer to show the visualization
