Abstract
An information processing apparatus acquires virtual viewpoint information of a plurality of frames contained in a virtual viewpoint video, selects a camera for shooting an image to be used in generating an image at a virtual viewpoint in a frame from a plurality of cameras with respect to each of the plurality of the frames based on a positional relationship between the virtual viewpoint information of each frame and viewpoint information of the plurality of the cameras, and reselects the camera selected for each of the plurality of the frames.
Claims6
An information processing apparatus comprising:
- an acquisition unit configured to acquire virtual viewpoint information of a plurality of frames contained in a virtual viewpoint video;
- a selection unit configured to select a camera for shooting an image to be used in generating an image at a virtual viewpoint in a frame from a plurality of cameras with respect to each of the plurality of the frames based on a positional relationship between the virtual viewpoint information of each frame and viewpoint information of the plurality of the cameras;
- and
- a reselection unit configured to reselect the camera selected for each of the plurality of the frames,
- wherein, if a camera selected for a target frame differs from a camera selected for a preceding frame of the target frame, and if a rate of covering an image at the virtual viewpoint of the target frame with a shot image of the camera selected for the preceding frame is greater than a predetermined value, the reselection unit changes the camera selected for the target frame to the camera selected for the preceding frame.
A method for information processing, the method comprising:
- acquiring virtual viewpoint information of a plurality of frames contained in a virtual viewpoint video;
- selecting a camera for shooting an image to be used in generating an image at a virtual viewpoint in a frame from a plurality of cameras with respect to each of the plurality of the frames based on a positional relationship between the virtual viewpoint information of each frame and viewpoint information of the plurality of the cameras;
- and
- reselecting the camera selected for each of the plurality of the frames,
- wherein, if a camera selected for a target frame differs from a camera selected for a preceding frame of the target frame, and if a rate of covering an image at the virtual viewpoint of the target frame with a shot image of the camera selected for the preceding frame is greater than a predetermined value, the camera selected for the target frame is changed to the camera selected for the preceding frame in the reselection.
