Abstract

A method for initializing a panoramic video by a graphical user interface (GUI) includes receiving a panoramic video, creating a three-dimensional mesh, and displaying a preview rendered from the three-dimensional mesh. The GUI displays a time selection interface and selects a frame time in the panoramic video with the time selection interface. The GUI displays a view selection interface and selects view parameters that define a camera orientation at the frame time of the panoramic video with the view selection interface. The GUI determines a selected frame of the panoramic video defined by the frame time and the view parameter, renders the thumbnail from the three-dimensional mesh based on the selected frame, and stores orientation data including the frame time and the view parameters.

Claims

1. A method for creating a thumbnail for a panoramic video, by a playback initialization tool, comprising:

receiving a panoramic video;

creating a three-dimensional mesh;

displaying a time selection interface;

selecting a frame time in the panoramic video with the time selection interface;

displaying a view selection interface;

selecting view parameters that define a camera orientation at the frame time of the panoramic video with the view selection interface;

determining a selected frame of the panoramic video defined by the frame time and the view parameters; and

rendering the thumbnail from the three-dimensional mesh based on the selected frame.

2. The method of claim 1, further comprising storing video frames at a regular time interval and wherein the selecting the frame time is at one of the regular time interval.

3. The method of claim 1, further comprising displaying a preview rendered from the three-dimensional mesh.

4. The method of claim 1, wherein the time selection interface comprises a slider mechanism for selecting a frame time between a beginning and an end of the panoramic video.

5. The method of claim 1, wherein the view parameters includes at least one of pan, tilt, roll, or zoom parameters.

6. The method of claim 1, wherein selecting the view parameters comprises dragging a cursor'"'"'s position across a camera viewing plane to rotate a camera orientation of the thumbnail.

7. The method of claim 1, further comprising re-rendering the thumbnail when the frame time and/or the view parameters are adjusted.

8. The method of claim 1, wherein the time selection interface and view selection interface are combined into a single user interface.

9. The method of claim 1, wherein the three-dimensional mesh is one of a Face-vertex mesh, a Winged-edge mesh, a Half-edge mesh, a Quad-edge mesh, a Corner-table mesh, and a Vertex-vertex mesh.

11. The method of claim 1, wherein the frame time selected is for a beginning of the panoramic video.

12. The method of claim 1, wherein the time selection interface comprises a slider mechanism for selecting a frame time between a beginning and an end of the panoramic video.

13. The method of claim 1, wherein the view parameters includes at least one of pan, tilt, roll, or zoom parameters.

14. The method of claim 1, wherein selecting the view parameters comprises dragging a cursor'"'"'s position across a camera viewing plane to rotate a camera orientation.

15. The method of claim 1, further comprising re-rendering the preview when the frame time and/or the view parameters are adjusted.

16. The method of claim 1, wherein the time selection interface and view selection interface are combined into a single user interface.

17. The method of claim 1, wherein the three-dimensional mesh is one of a Face-vertex mesh, a Winged-edge mesh, a Half-edge mesh, a Quad-edge mesh, a Corner-table mesh, and a Vertex-vertex mesh.

10. A method for setting camera orientation for a panoramic video, by a view orientation tool, comprising:

receiving a panoramic video;

creating a three-dimensional mesh;

displaying a preview rendered from the three-dimensional mesh;

displaying a time selection interface;

selecting a frame time in the panoramic video with the time selection interface;

displaying a view selection interface;

selecting view parameters that define a camera orientation at the frame time of the panoramic video with the view selection interface; and

storing orientation data comprising the frame time and the view parameters.

18. A method for initializing a panoramic video, comprising:

receiving a panoramic video;

creating a three-dimensional mesh;

displaying a preview rendered from the three-dimensional mesh;

displaying a time selection interface;

selecting a frame time in the panoramic video with the time selection interface;

displaying a view selection interface;

selecting view parameters that define a camera orientation at the frame time of the panoramic video with the view selection interface;

determining a selected frame of the panoramic video defined by the frame time and the view parameters;

rendering the thumbnail from the three-dimensional mesh based on the selected frame; and

storing orientation data comprising the frame time and the view parameters.
