Abstract: The indoor 3d reconstruction system based on virtual reality technology was designed to solve the problem that traditional 3d reconstruction system is time-consuming and inaccurate. The hardware part of the system consists of a laser scanning device, a Micro Blaze microprocessor and the FSL bus. On the basis of hardware, the point cloud data collected in indoor environment is preprocessed, and the point cloud data after preprocessing is matched and fused. After the point cloud data is converted to the global coordinate system, the 3d image is preliminarily reconstructed by using the OpenGL 3d graphics function library. After the texture patch processing, the error of 3d reconstruction results is verified to complete the design of 3d reconstruction system. Compared with the traditional 3d reconstruction system, it is proved that the designed system can reduce the time consumption of 3d reconstruction and improve the accuracy of 3d reconstruction.
