Abstract

The invention is applicable to the technical field of computer vision, and provides a VR generator based on three-dimensional reconstruction, and the VR generator is provided with a multi-view camera,a first processor, a second processor, a three-dimensional reconstruction module and a point cloud processing module, so that a wider field angle is provided, a more complete angle is covered, and the overlap ratio of two adjacent lenses is increased at the same time. More common points are provided for determination of the point cloud scale, and the robustness is improved. Meanwhile, key framesare extracted from to-be-processed frequencies shot by all cameras, and a first three-dimensional reconstruction model is made, so that the processed data volume is greatly reduced. Meanwhile, the second three-dimensional model is reconstructed and fused by adopting the three-dimensional data of the target object, high-density and high-precision measurement data can be obtained, and the VR generator has more advantages especially for three-dimensional measurement of a large-size object, so that the problem of poor authenticity in a virtual scene is solved, and the experience feeling of a useris improved.

Description

technical field

[0001] The invention belongs to the field of computer vision, in particular to a VR generator based on three-dimensional reconstruction. Background technique

[0002] 3D reconstruction technology is a branch of computer vision and a research direction combining computer vision and computer graphics and image processing. It is widely used in industrial automation, reverse engineering, cultural relics protection, computer-aided medical treatment, virtual reality, augmented reality and robot applications, etc.

[0003] Virtual reality (VR) is an emerging "professional-grade application" that has the potential to revolutionize the way a variety of tasks are performed. A 360-degree panoramic video is captured and used to create a computer-modeled 3D space. The user then wears custom-made goggles such as a head-mounted display (HMD), which actively selects and changes the user's perspective for an immersive experience.

[0004] In the prior art, a common lens-ba...
