Method for quickly and dynamically displaying different detail levels of point cloud data large scene

Abstract

The invention discloses a method for quickly and dynamically displaying different detail levels of a point cloud data large scene. The method comprises an architecture for displaying software and hardware and presentation between the architecture and the software and hardware. The architecture of the display software and hardware comprises a server side, a communication module and a browser, a point cloud database and an algorithm model based on a 3D scene are stored in the server side, the communication module internally comprises an instant display point cloud data transmission module and arole lens information transmission module, and the communication module is electrically connected with the server side and the browser. In the application process, the complexity of data transmissiondoes not depend on the complexity of a scene; and the browser only needs to cache a small part of data, a large amount of data and calculation are completed by the server, so that popularization and application are facilitated.

Description

technical field

[0001] The invention relates to the technical field of large point cloud data scenes, in particular to a fast and dynamic display method for different detail levels of large point cloud data scenes. Background technique

[0002] With the rapid growth of demand for web and mobile applications, it is critical to provide system and application personnel with web-based, interactive access to large virtual 3D scenes, such as panoramic 3D substations, virtual 3D BIM construction sites, etc., a The basic challenge is limited by the performance of current browsers. As the realism and complexity of 3D models increase, the browser often freezes or even crashes. Although acceleration and compression technologies can reduce the amount of 3D data, large-scale point clouds Data is still difficult to display on the browser side. Therefore, we focus on the communication between the browser and the server, which is independent of the complexity of the 3D scene, focuses on th...
