Design And Realization Of Wheat Oriented Cultivation Visualization System Based On Timing

With the continuous progress of society,people's overall cultural level continues to improve,the demand for knowledge is also increasing.First of all,due to the increasing demand for knowledge,how to effectively disseminate knowledge has become a research hotspot,knowledge visualization as a new field,the use of knowledge visual representation as the main way for the dissemination of knowledge has brought great convenience.Secondly,the current knowledge visual representation mainly uses charts,visual metaphor,knowledge animation and other means,there are heavy plane symbol elements,lack of interactive experience process and other deficiencies.The wide application of 3D visualization technology can make people feel different visual communication process and interactive experience,can make up for the current lack of knowledge visual representation.Based on the design of knowledge visualization based on 3D visualization technology,this paper puts forward the knowledge of wheat cultivation as the research object on the basis of the design of wheat,and the visualization of wheat cultivation is based on the design of wheat.System design and implementation.Through the wheat cultivation visualization system,it can fully understand the agronomic knowledge involved in wheat growth process management,provide a good visual interactive teaching material for wheat cultivation,and provide a high application value to guide the actual production of wheat and facilitate the promotion of wheat cultivation knowledge The At the same time,the design of knowledge visual representation based on 3D visualization technology has realized the innovation of knowledge visualization method.This paper mainly carries out the following research:(1)Design the knowledge visual representation based on 3D visualization technology,construct the mapping relationship between the knowledge element and the virtual space visualization element,integrate the interactive feature of the virtual space model object,and enrich the visual visualization of knowledge visualization.Firstly,the knowledge topological map and the knowledge minimum knowledge description unit are obtained by preprocessing knowledge.Secondly,the minimum knowledge description unit is decomposed from the knowledge composition structure to obtain the knowledge composition structure.Finally,the decomposed knowledge elements are compared with the three-dimensional virtual space elements Mapping.(2)On the basis of(1)design,the three-dimensional visualization of wheat cultivation knowledge was studied with wheat cultivation knowledge as the research object.The main steps are as follows: 1.According to the technical rules of wheat planting growth,the wheat growth schedule is established to describe the wheat planting growth sequence relationship.The wheat planting growth schedule is based on the wheat planting growth schedule.2.Set the correspondence between the growth season and the growth order of wheat.(3)Select the appropriate visualization engine and 3D virtual modeling software to develop the prototype of wheat cultivation system,and study the key techniques of land tillage and sprinkler effect in system development.The effect of land plowing is achieved by using the covering method.The effect of sprinkler spraying is realized by the combination of particle effect and surface material change.
