The focus of this paper is to develop a 3D reconstruction system for preserving fixed cultural relics, utilizing enhanced neural radiation field (NeRF) and multi view stereo matching technology. This study introduced octree partitioning and dynamic resolution rendering to optimize NeRF visualization and minimize costs. Compared to alternative technologies such as radar and structured light scanning, NeRF is an economically efficient, highly automated, and seamless solution. In addition, Gaussian mapping is used to improve the quality of the reconstructed model. In a case study involving important cultural heritage, NeRF showed better results compared to traditional methods. The system integrates data management, NeRF reconstruction, and visualization functions. However, as the number of partitions increased, it encountered challenges such as compatibility issues and performance degradation. Future research directions will focus on improving the model transformation process, developing efficient partitioning algorithms, and implementing dynamic node addition to enhance system flexibility and stability. These advances aim to support the digital protection of cultural relics and raise public awareness of their importance.
