Embodiment Construction

[0038] Real-scene 3D online application system, in which: the city-level true 3D model has the characteristics of a large amount of data, and it is difficult for traditional 3D rendering technology to render such a large 3D scene. Algorithm optimization and innovation are carried out on the basis of traditional 3D model data visualization technology, which integrates real-time occlusion data clipping algorithm, quadtree structure level of detail (LOD) model and data dynamic loading technology, which can quickly display and analyze massive data True 3D data, which is close to people's natural observation method, represents a 3D city model with rich geometric details and photo texture, and has a visual experience and spatial perception that are close to the real world.

[0039] Real-scene 3D online application system, among which: the real-scene 3D online application system involves a wide variety of data, and requires high-performance rendering technology. In view of the charac...

Abstract

The invention provides a real-scene three-dimensional visualization online application system. The real-scene three-dimensional visualization online application system is characterized in that a modelqueue rendering algorithm, a real-time occlusion data cutting algorithm, a data cutting technology of the real-time occlusion cutting algorithm, a multi-resolution LOD technology based on a quadtreestructure and a data dynamic loading technology are adopted in the system; the system functions include layer management, terrain transparency, underground browsing, north pointing top view, flight paths, scene roaming, surround browsing, map bookmarks, double-screen comparison, recording browsing, video monitoring, GPS tracks, electronic maps (two-dimensional eagle eyes, two-dimensional superposition, map linkage and two-dimensional maps), screenshots and the like, and the purpose of multi-source, multi-mode and multi-directional browsing display of three-dimensional data is achieved.

Description

technical field [0001] The invention relates to the field of surveying and mapping geographic information. It is a 3D platform based on BS model. By displaying city-level high-precision real-scene 3D model data, it provides real basic geographic entities for various government departments, combined with multi-source data display on the platform. Functions and various data integration and sharing provide strong support for the construction of smart cities. Background technique [0002] At present, the general 3D platform is built in the CS mode, and the use of the platform is only used by a certain government department, and the platform has not been shared. The real-scene 3D platform built in BS mode needs to transmit the city-level massive real-scene 3D model data online through the network, and the speed of massive data loading is also one of the important factors currently considered. The conventional 3D platform also has the basic functions of the 3D space environment, ...
