Application of 3D Image Technology in Rural Planning

The well-being of villages and villagers is directly related to the development of urban-rural relations. Rural development is an important part of poverty alleviation, as well as the main goal and means of rural rejuvena-tion, because rural planning affects rural economic development and rural revitalization. Electronic imaging can improve the speed of rural area planning, and can also model the planned scheme. However, the current rural planning still lacks top-level design, which cannot improve the overall structural design of rural plan-ning, and the data resources of rural planning are not perfect. Therefore, this article studied the direction of rural planning and design by analyzing the focus, problems, and external environment characteristics of rural planning, and then analyzed the application characteristics in rural planning according to the process of 3D image technology. By reducing the complex design links in rural planning, the office efficiency of planning and the 3D visualization of planning model can be promoted, so as to improve the effect of rural planning and the construction service of rural planning. The simulated annealing algorithm showed that the planning efficiency and average planning speed of 3D image application in rural planning were gradually increasing; the average planning efficiency was about 1.80, and the average planning speed was about 1.05. The plan-ning efficiency increased by 1.20 in the whole process, while the average planning speed increased by 0.33 in the whole process. Through comparison, it can be seen that the planning rationality of rural planning under 3D image was 12.16% higher than the original one, while the measurement error rate of some teachers was 47.28% lower. In a word, 3D imaging and electronic imaging can improve the architectural design and layout planning of rural planning.
