Problems solved by technology

When the shared resources required by users include both the video information of the collaborative workspace and the 3D geometric model of the grid service results, the video service and audio service currently provided by the access grid can no longer meet the needs of users for this type of grid application

Embodiment Construction

[0021] According to the requirements of the current access grid and the characteristics of augmented reality technology, the present invention defines the concept of "Augmented Video Services (AVS)": the three-dimensional geometric model of the grid service result can be combined with the access grid The real video scene is integrated to provide users with an access grid service that combines virtual and real enhanced video resources and 3D geometric model operation methods. Augmented reality can use computer-generated virtual objects to enhance the real world, "enhanced video service" follows the name of "enhanced" in "augmented reality"; at the same time, "enhanced video service" is an extension of access grid video service, Therefore, the name "video service" is also used.

[0022]Refer to Figure 1 for a composition structure diagram of an enhanced video service. The enhanced video service includes an Augmented Video Producer Service (AVPS for short) and an Augmented Video ...

Abstract

The invention provides a method used for realizing an enhanced video service mode of an access grid. The method includes the following steps: registering a 3d geometric mode of the gridding service result to a real video scene of the access grid, so as to generate an enhanced video stream which compounds the geometric mode of the gridding service result with the video sequence of the access grid; then according to application characteristics of the gridding, transmission ways of the enhancement video information are given, including a PTPR way and a PTCR way, and the sharable enhancement video stream is provided for each user who visits the gridding; and finally, a conversation notice protocol and a conversation description protocol are utilized to manage the enhancement video conversation of the visiting gridding. By using the invention, the users are able to operate the 3d geometric mode of the gridding service result in a cooperation work space of the access grid, thus completing the cooperation work tasksbased on the grid service result in the access grid environment.

Description

technical field [0001] The invention relates to the fields of access grid and augmented reality, in particular to a new enhanced video service mode oriented to access grid applications. Background technique [0002] Access Grid (AG for short) is an important part of grid technology and the access interface of the grid system. Grid applications provide an immersive, interactive, and collaborative access environment, mainly including communication methods between groups, grid resource access methods, and user operation collaboration methods. After multiple access grid users enter the collaborative work environment, they often need to collaboratively operate the 3D geometric model of the grid service results in the video scene describing the real environment, which requires the access grid to expand its service functions to support this type of typical The application provides the sharing service of the 3D geometric model in the video scene at the same time, and supports the i...
