Analysis of 3D Reconstruction of Large-Scale Architectural Scene Based on Virtual Reality

Aiming at the rapid modeling of virtual reality large-scale architectural scene, this paper designs a method to reconstruct large-scale architectural scene by virtual reality. The method uses the advanced high frequency laser to carry on the solid scanning of the large construction scene, realizes the quick captures of the scene characteristic, and achieves rapid establishment of 3D model of the large-scale architectural scene through a certain feature extraction and logical projections. Experiments showed the effectiveness of the method, and proved that the use of virtual reality for 3D reconstruction of large-scale architectural scene can effectively solve the problem of modeling speed.
