Design of 3D Garden Landscape Design Simulation System Based on Virtual Reality and Neural Network Model

Garden landscape is the soul pillar in architectural design, which directly represents the taste and grade of architectural design. Aiming at the problem of poor simulation effect of current landscape planning, this paper designs a new 3D garden landscape design simulation system by combining VR (Virtual Reality) and neural network model. This system is based on Visual Studio C++development platform, 3DS Max modeling tool and OpenGL, a 3D graphics development application library, and is realized by using object-oriented design and object-oriented programming technology. Use 3DS Max’s powerful 3D graphics modeling function to model. The improved YOLOv5 model is used to identify the landscape, and the depth separable convolution is used to replace the ordinary convolution, so as to further reduce the model parameters and achieve the effect of lightweight model. The system realizes the real-time recognition of the landscape in the actual environment. The system test results show that the average score of the final effect of the garden landscape designed by this system is 96.223, and the scoring results show that this system has high design authenticity, which improves the immersion effect and realism of the system.
