Research on landscape design system based on 3D virtual reality and image processing technology

Abstract

In order to ensure the rationality of landscape design, it is of great practical significance to simulate the planning effect. Aiming at the problems of two traditional landscape planning effect simulation systems, a new landscape planning effect simulation system was designed based on virtual reality technology. The overall framework of the system is composed of user layer, application layer and display layer. According to the system frame structure, hardware such as acquisition equipment, main control equipment, output and display equipment are selected; according to the system framework structure, the system software is designed to run the main program. In addition, this paper also based on 3D image processing technology landscape design system. In the design process, 3D landscape image can be preprocessed to remove noise information and redundant information, and 3D landscape image feature enhancement method is used to realize 3D landscape image feature enhancement and improve the clarity of landscape design image. Combined with the example of garden green space, according to the parametric plant modeling method, the morphological structure parameters of green plants are obtained, and the three-dimensional models of various plant modeling are established; the rules of parametric description of plant spatial layout are adopted, based on the open scene graph rendering engine, and the oculus rift virtual reality equipment is integrated to realize the virtual construction and display of three-dimensional garden vegetation landscape. The results show that the design effect of the system is very clear and of good quality. It has a high score in the design of courtyard landscape and garden landscape, and the system has low application cost, low energy consumption and high operation efficiency.
