Artificial intelligence technology and its application in interior and exterior decoration design of modern buildings

In order to improve the effect of interior and exterior decoration design of modern building, this paper combines artificial intelligence technology to build a modern interior and exterior decoration design system of modern building. In this paper, the method of combining model-driven and data-driven is adopted, combines the advantages of model-driven method with obvious object details and edges to construct an initial model based on point cloud, which improves the work efficiency, the degree of automation and the accuracy of the initial value of the model, and is conducive to the guarantee of 3D reconstruction of the model. Through the experimental research, it can be seen that the interior and exterior decoration design system of modern building based on artificial intelligence proposed in this paper can effectively improve the design effect of building decoration.
