摘要： Methods and apparatus for making environmental measurements are described. In some embodiments different devices are used to capture environmental information at different times, rates and/or resolutions. Environmental information, e.g., depth information, from multiples sources captured using a variety of devices is processed and combined. Some environmental information is captured during an event. Such information is combined, in some embodiments, with environmental information that was captured prior to the event. Environmental depth model is generated in some embodiments by combining, e.g., reconciling, depth information from at least two different sources including: i) depth information obtained from a static map, ii) depth information obtained from images captured by light field cameras, and iii) depth information obtained from images captured by stereoscopic camera pairs. The reconciliation process may involve a variety of information weighting operations taking into consideration the advantages of different depth information sources and the availability of such information.

摘要： Methods and apparatus for allowing a user to switch viewing positions and/or perspective while viewing an environment, e.g., as part of a 3D playback/viewing experience, are described. In various embodiments images of the environment are captured using cameras placed at multiple camera positions. During viewing a user can select which camera position he/she would like to experience the environment from. While experiencing the environment from the perspective of a first camera position the user may switch from the first to a second camera position by looking at the second position. A visual indication is provided to the user to indicate that the user can select the other camera position as his/her viewing position. If a user input indicates a desired viewing position change, a switch to the alternate viewing position is made and the user is presented with images captured from the perspective of the user selected alternative viewing position.

摘要： Methods and apparatus for implementing user controlled zoom operations during a stereoscopic, e.g., 3D, presentation are described. While viewing a 3D presentation of a scene environment, a user may switch to a zoom mode allowing the user to zoom in on a particular portion of the environment being displayed. In order to maintain the effect of being physically present at the event, and also to reduce the risk of making the user sick from sudden non-real world like changes in views of the environment, the user in response to initiating a zoom mode of operation is presented with a view which is the same or similar to that which might be expected as the result of looking through a pair of binoculars. In some embodiments the restriction in view is achieved by applying masks to enlarged version of left and right eye views to be displayed.

摘要： Content delivery and playback methods and apparatus are described. The methods and apparatus are well suited for delivery and playback of content, corresponding to a 360 degree environment and can be used to support streaming and/or real time delivery of content, e.g., 3D content, corresponding to an event such as a sports game, e.g., while the event is ongoing or after the event is over. Portions of the environment are captured by cameras located at different positions. The content captured from different locations is encoded and made available for delivery. A playback device selects the content to be received based in a user's head position. Streams may be prioritized and selected for delivery based on the user's current field of view and/or direction of head rotation. Static images or synthesized images can be used and combined with content from one or more streams, e.g., for background, sky and/or ground portions.
