Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0040] like figure 1 As shown, the system structure adopted in this embodiment includes: a server composed of a Web server 11, a database 12, and a streaming media server 13, a network based on a network data transfer protocol 14 (RTSP, FTP or HTTP, etc.) transmission, and a 3D display front desk 15 And the client of geographic information front desk 16. The client sends the selected geographical position information to the Web server through the network, and the Web server queries the database 12 according to the request, and returns the access address of the streaming media file corresponding to the panorama image closest to the current geographical position, and the address in the streaming media file. Offset (what this embodiment adopts is the FTP transfer protocol, and this offset represents the number of bytes from the initial position of t...

Abstract

The invention relates to a streaming media application method in panoramic virtual reality roaming. Panoramic streaming media integrated with additional information is applied to panoramic virtual roaming and the panoramic virtual roaming with continuous viewpoints is realized. The streaming media application method in panoramic virtual reality roaming comprises the following steps of: 1) compressing and encoding image data by utilizing a streaming media video compressing and encoding manner and integrating the additional information; 2) determining an initial user roaming location, returningcorresponding streaming media file information to a client through inquiring a database, analyzing streaming media files, and establishing a data structure used for buffer management; and 3) displaying panoramic images and the additional information, and displaying additional information corresponding to each frame of panoramic image in panoramic virtual roaming in a manner of continuous viewpoints. According to the streaming media application method in panoramic virtual reality roaming, the panoramic images and the additional information are compressed into a streaming media format, thus thedefects of the traditional network-based panoramic virtual roaming are overcome, the user waiting time is shortened, and a novel technical line is provided for the network data transmission in panoramic virtual reality roaming.

Description

technical field [0001] The invention relates to streaming media technology, Internet technology and virtual reality technology, in particular to a streaming media application method in panorama virtual reality roaming. Background technique [0002] In the prior art, streaming media is also called streaming media, which is used in video-on-demand and video conferencing. After the user decompresses the data through the decompression device, the program will be displayed in the state before transmission. [0003] Streaming is a new way of delivering media. The streaming transmission method is to divide the entire multimedia files such as A / V and 3D into compressed packages through a special compression method, and transmit them continuously and in real time from the video server to the user computer. In a system that adopts the streaming transmission method, the user does not have to wait until the entire file is downloaded as in the download method, but only needs to go thro...
