Application of Visual Communication in the Three-Dimensional Image Design of Interior Architecture

This study explores the application of visual communication design in interior architectural three-dimensional image design, aiming to solve the problems of unclear definition of indoor LoD, low modeling efficiency and insufficient integration of indoor space information in smart city construction. The research method is based on visual communication design, which enhances the expressiveness and user experience of interior design through the integration of visual elements such as graphics, color and typography. First, this study introduces the application of visual communication design in automated modeling, using visual recognition technology to automatically generate three-dimensional models from floor plans, which significantly improves modeling efficiency. Secondly, the application of visual communication design in indoor navigation and positioning services is studied to provide more intuitive navigation instructions through augmented reality technology, thereby improving the accuracy and user experience of indoor navigation. Experimental results show that the visual communication method performs well in LoD evaluation under different view conditions, with significant advantages over traditional methods in terms of geometric accuracy, texture quality, element integrity, and indoor LoD similarity. In addition, the application of visual communication improves the efficiency of indoor 3D image design and improves the integration of indoor space information. The evaluation of the rationality of element layout reaches 94.15%, providing a more effective indoor architectural 3D image design solution for smart city construction. plan.
