Problems solved by technology

Although this method is simple and direct to implement, the interactivity is determined by the network performance, and most current network protocols (such as TCP / IP, etc.) only support best-effort, and the delay is not controllable, so the interactivity cannot be achieved as it should be.

Embodiment Construction

[0029] The present invention adopts the C / S mode, the main server requires strong processing ability, and has no special requirements for the client. The user first establishes a connection with the main server and submits a request. The main server sends the initial frame to the client for display. The initial frame mainly includes the following information: color information, depth information, and camera-related parameters. The user browses the scene through the mouse or keyboard, and the system converts the interactive information into corresponding observation parameters (such as observation point, observation direction, etc.), and sends it to the main server and IBR processing for the client.

[0030] The main server and the service provider constitute the server side. The main server mainly completes the work of loading and rendering the 3D model, and generating corresponding view information according to user interaction information. The service provider is used to p...

Abstract

This invention discloses a 3-D remote visualization method including: 1,the customer end receives an interactive order sent by a user and analyses it, 2, the customer end presents a request for browsing a 3-D model to the server end and the visual position of the user to require to get the accurate views, 3, a primary server analyses the request and judges it to fetch the required model file from the database of the primary server or a server provider or prompt it to the user, 4, the primary server romances the model file to generate an accurate view, 5, the primary server compresses the view color information and depth information, 6, the primary server sends the got compressed file and the visual positions to the customer end, 7, the customer de-compresses the file and positions to store them in a buffer and display the color information.

Description

technical field [0001] The invention belongs to the technical field of network applications, and in particular relates to a three-dimensional remote visualization method based on Image Based Rendering (IBR). Background technique [0002] As an important branch of visualization technology, remote visualization plays an increasingly important role in the development of computers. This is mainly because it enables ordinary users to use the remote high-performance visualization system to complete the visualization work that they are not capable of and realize the browsing of remote virtual scenes. However, due to the limitation of network bandwidth and many other reasons, there is still no effective method to complete remote visualization work. [0003] Most of the current remote visualization technologies mainly adopt two implementation methods. [0004] One is to download the virtual scene or 3D model data to the client computer, and re-draw for browsing. This method has th...
