AI Technical Summary

Technical Problem

Existing 4D scene modeling technologies have difficulty accurately capturing the movement and changes of scenes in the temporal dimension, resulting in poor reconstruction effects and the inability to provide immersive virtual reality and augmented reality experiences.

Method used

By acquiring multi-view videos, a three-dimensional scene model at the initial moment is generated. The deformable network is combined with the camera pose information to determine the four-dimensional scene model corresponding to the multi-view video, capturing the geometric structure and surface features of the scene, and modeling the time dimension at the same time.

Benefits of technology

The accuracy and effect of four-dimensional scene reconstruction have been improved, which can better display the movement and changes of dynamic scenes and enhance the user's immersive experience.

Abstract

The embodiment of the invention discloses a four-dimensional scene reconstruction method and device and electronic equipment. According to one specific embodiment, the method comprises the steps that a multi-view video is acquired, the multi-view video comprises a multi-view picture, and the multi-view picture is a video frame at an initial moment in the multi-view video; generating a three-dimensional scene model corresponding to the multi-view picture; determining a deformable network corresponding to the multi-view video according to the three-dimensional scene model, the multi-view video and the camera pose information corresponding to the multi-view video; and determining a four-dimensional scene model corresponding to the multi-view video according to the three-dimensional scene model and the deformable network. According to the embodiment, the motion and change of the scene can be accurately captured, so that the reconstruction effect of the four-dimensional scene is improved.
