Dynamic update and feedback mechanism of building three-dimensional model based on Internet of Things

This paper proposes a dynamic update and feedback mechanism of building three-dimensional model based on Internet of Things, aiming to realize real-time visualization and optimized management of building information. Multi-dimensional data is collected through Internet of Things technology, combined with dynamic update algorithm, real-time information is efficiently mapped to three-dimensional model, ensuring that the model is consistent with the actual building status. A user interaction feedback system is designed, and the model accuracy is optimized by user rating and anomaly annotation, which significantly improves the adaptability and robustness of the system. Experimental verification shows that this method can maintain a low response time under different load conditions, and reduce the model error by up to 70% through the feedback mechanism. The research results show the potential of combining Internet of Things with three-dimensional modeling technology, provide innovative solutions for building information management, and have important practical value.
