Exploration of Industrial Architectural Heritage Display Method Combining Engineering Algorithm and Virtual Reality Technology

With the increasing demand for the protection and display of industrial architectural heritage, especially the The Legacy of the Third Front, traditional display methods face problems such as insufficient informatization and poor interactivity. In order to solve these problems, this paper combines engineering algorithms with virtual reality technology to propose an innovative display method for industrial architectural heritage. First, the Multi-View Stereo (MVS) algorithm is used to reconstruct the architectural heritage with high-precision 3D point cloud data. The MVS algorithm obtains image data from multiple perspectives and accurately reconstructs the complex structure of the building. Then, the least squares method is used to correct and optimize the point cloud data to ensure the accuracy and stability of the reconstructed model. Finally, virtual reality technology is used to transform the reconstructed 3D model into an interactive display environment, allowing users to immersively experience the historical features of the architectural heritage and conduct detailed exploration and analysis. Experimental results show that the 3D reconstruction based on the MVS algorithm has excellent performance in accuracy and stability, with an average root mean square error (RMSE) of 0.0886 m, which meets the needs of high-precision display. The virtual reality display system significantly improves the user’s sense of immersion and interactivity. Users generally report that the operation is simple and the visual effect is good. The user operation is smooth and the learning time is short, showing good user friendliness. In the above data conclusions, the method proposed in this paper has significant advantages in the digital reconstruction and virtual reality display of industrial architectural heritage, providing effective technical support for heritage protection and display.
