Research On 3D Data Visualization Of Forest Ecological Station

In the contemporary era of information,how to efficiently display the essential information contained in the massive data has become a key and difficult problem.For the forestry station,the massive data is very difficult to manage,the data and the scene is separated.In order to solve these problems,this paper presents a complete method from data acquisition to visualization.Based on the data acquisition equipment of collection node and sink node,the data of forestry station can be obtained.Building a three-dimensional model of the forestry station with Unity3D,optimizing the scene with LOD technology,reducing the number of triangular patches of entire scene,the system operating efficiency can be greatly improved.After connecting to the database,forest station data can be read and visualized in 3D scene.In real-time display,3D scene can be changed by data in real time.Leaf color,scene light intensity and fog concentration and other indicators of scene changes,showing the data collected.In analysis of the data set,the t-SNE algorithm is introduced,and the similarity between data items is calculated by combining the dimension attributes.The data dimension are effectively reduced,and the one-sidedness in analyzing a single property is avoided.Simultaneously,comparing the data items and standard data to find their similarity,and classifying data items effectively,the results are displayed in a three-dimensional form in the scene.The experimental results show that the forestry data can be effectively collected and 3D visualized by using the method of this paper,the effect is good.
