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 stereoscopic image encoding and decoding are described. Left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.

摘要： A camera rig including one or more stereoscopic camera pairs and/or one or more light field cameras are described. Images are captured by the light field cameras and stereoscopic camera pairs are captured at the same time. The light field images are used to generate an environmental depth map which accurately reflects the environment in which the stereoscopic images are captured at the time of image capture. In addition to providing depth information, images captured by the light field camera or cameras is combined with or used in place of stereoscopic image data to allow viewing and/or display of portions of a scene not captured by a stereoscopic camera pair.

摘要： Encoding and streaming methods and apparatus are described. Objects in negative parallax in frame pairs, e.g., pairs of left and right eye images forming a stereoscopic image, are identified. An amount of negative parallax reduction implemented depends, in some embodiments, on the data rate being used for encoding and/or the amount of negative parallax detected in the frame pair to be encoded. The lower the supported data rate the greater the reduction in negative parallax in some embodiments. In some, but not all, embodiments objects in positive parallax, e.g., objects appearing to go into the page, are not subject to parallax reduction. When a lowest supported data rate is used mono encoding is used and parallax reduction steps are skipped. The same frame pair is encoded multiple times at different data rates. Different amounts of negative parallax reduction are performed for at least some of the different supported data rates.

摘要： Methods and apparatus for streaming or playing back stereoscopic content are described. Camera dependent correction information is communicated to a playback device and applied in the playback device to compensate for distortions introduced by the lenses of individual cameras. By performing lens dependent distortion compensation in the playback device edges which might be lost if correction were performed prior to encoding are preserved. Distortion correction information may be in the form of UV map correction information. The correction information may indicate changes to be made to information in a UV map, e.g., at rendering time, to compensate for distortions specific to an individual camera. Different sets of correction information may be communicated and used for different cameras of a stereoscopic pair which provide images that are rendered using the same UV map. The communicated correction information is sometimes called a correction mesh since it is used to correct mesh related information.

摘要： Camera related methods and apparatus which are well suited for use in capturing stereoscopic image data, e.g., pairs of left and right eye images, are described. Various features relate to a camera rig which can be used to mount multiple cameras at the same time. In some embodiments the camera rig includes 3 mounting locations corresponding to 3 different directions 120 degrees apart. One or more of the mounting locations may be used at a given time. When a single camera pair is used the rig can be rotated to capture images corresponding to the locations where a camera pair is not mounted. Static images from those locations can then be combined with images corresponding to the forward direction to generate a 360 degree view. Alternatively camera pairs or individual cameras can be included in each of the mounting locations to capture video in multiple directions.
