Modeling And Simulation Of Rural Virtual Orchard In The Implementation Of Rural Revitalization Strategy

Implementing the rural revitalization strategy is an important strategic measure to achieve endogenous development in rural areas.It is necessary to pay attention to the construction of ecological civilization in rural areas,build a modern agricultural industrial system,production system,and management system,and pay attention to the application of Internet and artificial intelligence technology.China's orchard area and fruit production rank first in the world.The orchard has become an important support for the local“ecological livable” and a pillar industry for income growth,and plays an important role in the development of rural economy.At present,the overall level of orchard management in China is quite different from that of international advanced countries.In particular,the gap between digitalization,informationization and intelligent management of orchard is greater.Therefore,relying on the modeling and simulation technology of virtual reality to construct a modern virtual orchard in rural areas and develop informational and intelligent orchard is an urgent need to accelerate the gap between developed countries and realize rural revitalization.It is important for accelerating the modernization of agriculture and rural areas.Realistic meaning.The virtual orchard can be regarded as a digital,virtual orchard.It is an information system based on virtual reality technology,geographic information technology to combine orchard information and other scene information,and presented in three-dimensional visualization and virtual reality scene interface.This paper uses virtual reality technology to explore the modeling and simulation methods of virtual orchard.The main research contents and work are as follows:1)Firstly,the research on the modeling and simulation of domestic agricultural commercial promotion and orchard roaming is reviewed.According to the characteristics of Lingnan fruit,the virtual roaming scene of citrus orchard was constructed.The model data reduction technology of big data information and the grid data reduction method of 3D model were explored.2)On the basis of the virtual orchard,in order to increase the promotion value of agricultural products and scenes,event triggering is added in relevant parts to achieve the corresponding promotion of goods and concept tourism.3)The key issues in the roaming technology of virtual scenes are studied.Orchard scene modeling is the main component of the virtual orchard roaming system.It is the most important form of virtual reality technology.It is an interactive simulation environment that enables users to have an immersive feeling,and realizes the direct natural interaction between the user and the environment.4)Starting from the characteristics of virtual reality immersive equipment,according to the virtual reality helmet or virtual reality platform,the user's expression can be extracted in real time,and then the characterization meanings of these expressions are extracted and analyzed to facilitate optimization of users.5)Finally,starting from the requirements of the virtual reality system,using the open platform Unity3 D to build the virtual orchard simulation,realize human-computer interaction,realize the realistic virtual orchard environment and agricultural robot operation planning,and realize the virtual orchard roaming based on the network.Through the development of virtual orchard and its intelligent orchard agricultural machinery,it provides technical support for the construction of modern agricultural industrial system and the digital and network management of fruit products throughout their life.
