Problems solved by technology

[0004] However, when the above solution is adopted, the display terminal needs to splice and display each sub-model, and there will be splicing gaps between adjacent sub-models, especially the gap between adjacent sub-models with different degrees of fineness is more obvious, which affects the display quality of the model

Embodiment Construction

[0037] In recent years, with the development of VR technology, 3D reconstruction has gradually become a popular research topic in the field of 3D display. 3D reconstruction refers to the process of reconstructing 3D information from single-view or multi-view images.

[0038] 3D reconstruction can be divided into static 3D reconstruction and dynamic 3D reconstruction. For some static scenes and objects, the 3D models of the scenes and objects are reconstructed by static 3D reconstruction algorithms, and then rendered and displayed in the 3D scene. For some dynamic objects (such as: people), because of dynamic changes, it is often necessary to establish a series of 3D models, and render and display these 3D models in order to describe the motion state of the object.

[0039] The real-time remote 3D communication system is an important application scenario of dynamic 3D reconstruction. After the acquisition terminal reconstructs the 3D model based on the collected image data, th...

Abstract

The invention relates to the technical field of virtual reality, provides a three-dimensional model display method and device, and can solve the problem of splicing gaps between sub-models with the same precision and sub-models with different precision. For the splicing gaps between the sub-models with the same precision, the vertexes contained in the adjacent sub-models with the same precision are updated through the intersection points of the edges of the triangular patches generated by the vertexes and the common surfaces of the corresponding cuboids, and due to the fact that the positions of the intersection points corresponding to the two coplanar cuboids are the same, the adjacent sub-models with the same precision can completely coincide at the splicing position. Therefore, splicing gaps between the sub-models with the same precision are reduced; according to the splicing gap between the sub-models with different precisions, at least one new triangular patch is generated in the non-closed tangent plane of the adjacent sub-models, so that the adjacent sub-models with different precisions are located in closed spaces of different cuboids, and the splicing gap between the sub-models with different precisions is reduced. Through the method provided by the invention, the display quality of the three-dimensional model can be improved.

Description

technical field [0001] The present application relates to the field of virtual reality (Virtual Reality, VR) technology, and in particular to a method and device for displaying a three-dimensional model. Background technique [0002] In the real-time remote 3D communication system, due to the real-time transmission of multiple 3D model data (including geometric data and texture data), and the 3D model data of each frame is different, the total amount of data is huge, which increases the pressure on network bandwidth, resulting in When the frame rate of the action of the 3D model is insufficient on the display terminal, the action of the 3D model may freeze. [0003] In order to solve the problem of model motion jamming, related technologies have generated 3D models of different precision, and segmented the models, completely sent the reconstruction data of each low-precision sub-model, and independently transmitted the data of each high-precision sub-model, Therefore, under...
