Entry mode of pictures of three-dimensional large scene

Abstract

The invention relates to an entry mode of pictures of a three-dimensional large scene. According to the mode, a group of positioning points is selected as positioning end points; projection coordinates are moved to the positioning end points along the spatial axial direction of a three-dimensional model; and the fusion and the transition of the three-dimensional images and panoramic pictures are realized in the moving process. The mode has the beneficial effects that in the moving process, the connection of two dimension and three dimension is realized through the fusion of the three-dimensional images and the panoramic images; in the process of entering or flying out of roaming, an observer is in the three-dimensional image observation mode; and therefore, the visual projection effect isguaranteed, the browsing experience is improved and the three-dimensional model capable of showing a real and stereoscopic projection effect is provided.

Description

technical field [0001] The invention relates to the technical field of three-dimensional imaging modeling, in particular to a screen entry method of a three-dimensional large scene. Background technique [0002] The fly-in and fly-out method of the existing 3D large scene adopts the THREE.js technology of the webgl engine. [0003] So far, there are mainly two types of roaming experience provided by the market: only through three-dimensional way, only through two-dimensional way. The only way to use 3D is to use 3D engine technology. Generally, there are only 3D models without 2D panoramas. The display effect of this method is: when the camera is moved, it is truly roaming in the 3D scene. However, the 3D models in the prior art are generally made relatively rough, which directly leads to the lack of realistic presentation effect in this way. In the second way, if it is a two-dimensional rendering technology of traditional web pages, such as Baidu Street View and Google St...

However, the 3D models in the prior art are generally made relatively rough, which directly leads to the lack of realistic rendering effect in this way

And the second method, if it is the two-dimensional rendering technology of traditional web pages, such as Baidu Street View and Google Street View, can only do two-dimensional roaming, and the rendering effect is not realistic and three-dimensional.

[0004] Therefore, whether it is a purely three-dimensional method or a purely two-dimensional method, the presentation effect is lacking in reality and three-dimensionality. The main reason is that it is technically impossible to realize the connection between two-dimensional and three-dimensional
