Abstract

A non-transitory computer readable storage medium includes a computer-readable code for executing a method of video playback, capable of displaying a video file in a three-dimensional environment (2) from any perspective, by projecting two-dimensional frames (1) of the video file on said environment (2), according to a position and perspective assigned to the frame (1).

Claims

1. A non-transitory computer readable storage medium comprising:

a computer-readable code for executing a method of video playback, wherein the video comprises a plurality of two-dimensional frames (1), each frame (1) having an assigned playback time, characterized in that the method comprises;

assigning to each frame (1) of the video a position and perspective in a three-dimensional environment model (2);

the method comprising;

for a given playback time;

determining an area of the three-dimensional model (2) to be visualized;

projecting the frame (1) with said given playback time on the three-dimensional model (2) according to the position and perspective assigned to said frame (1);

displaying the area to be visualized of the three-dimensional model (3) with the projected frame (1).

2. The storage medium according to claim 1 characterized in that the playback time is determined by means of user commands.

3. The storage medium according to claim 1 characterized in that the area to be visualized is determined by means of user commands.

4. The storage medium according to claim 1 characterized in that, for a given playback time, the area to be visualized corresponds to a perspective from the position associated to the frame (1) with said given playback time, being the area to be visualized wider than the projection of said frame (1).

5. The storage medium according to claim 1 characterized in that the method comprises receiving user commands to switch the area to be visualized between:

a first area determined by user commands,

a second area corresponding to a perspective from the position associated to a frame (1) being played, being the area to be visualized wider than the projection of said frame (1); and

in that the area to be visualized is switched keeping the playback time unchanged.

6. The storage medium according to claim 1 characterized in that the method comprises receiving user commands to switch to a two-dimensional playback mode in which, for a given playback time, only the two-dimensional frame (1) with said given playback time is displayed, and in that when switching to the two dimensional playback mode, the playback time is kept unchanged.

7. A computer program comprising:

a non-transitory computer readable storage medium comprising

a computer-readable code for executing a method of video playback, wherein the video comprises a plurality of two-dimensional frames (1), each frame (1) having an assigned playback time, characterized in that the method comprises;

assigning to each frame (1) of the video a position and perspective in a three-dimensional environment model (2);

the method comprising;

for a given playback time;

determining an area of the three-dimensional model (2) to be visualized;

projecting the frame (1) with said given playback time on the three-dimensional model (2) according to the position and perspective assigned to said frame (1);

displaying the area to be visualized of the three-dimensional model (3) with the projected frame (1).

said program running on a computer, a digital signal processor, a field-programmable gate array, an application-specific integrated circuit, a micro-processor, a micro-controller, or any other form of programmable hardware.
