    摘要： There is provided a method of providing stereoscopic content, the method comprising: transmitting, to a playback device (800), first correction information (742) for a first camera (1302), wherein the first correction information (742) includes information indicating one or more adjustments to be made to node locations in a first texture map (740), wherein the first correction information (742) includes information generated based on measurement of one or more optical characteristics of a first lens of said first camera (1302), and wherein each node position in the first texture map corresponds to a vertex of an environment-specific model (838, 1500); transmitting, by a server (114) to the playback device (800), a first rendering instruction to use the first correction information, the first texture map (740), and the environment-specific model (838, 1500) for image rendering; and operating said server (114) to transmit a content stream including encoded images generated from image content captured by said first camera (1302).

    摘要： The present invention relates to object visualization. In order to provide a facilitated visualization of a subject's interior structure, an object visualization device (10) is provided comprising an image supply (12), a data processor (14) and an output (16). The image supply provides a 2D X-ray image of the object and also 3D data of the object. The data processor registers the 3D data to the 2D X-ray image and detects a viewing direction of the 2D X-ray image. The data processor also determines a viewing direction for a matching view of the 3D data based on the viewing direction of the 2D X-ray image. The data processor generates a pair of stereoscopic images (24) of the 3D data for the determined viewing direction and combines the 2D X-ray image with one of the images of the pair of stereoscopic images resulting in an augmented first stereoscopic image (26), whereas the other one of the pair of stereoscopic images remains as a generated second stereoscopic image (28). The output provides the augmented first stereoscopic image and the generated second stereoscopic image as an enhanced pair (30) of stereoscopic images providing an augmented 3D view of the object. Although only one of the stereoscopic images is provided with the additional X-ray image content information, in the combined view by both eyes, the X-ray information is also transferred to the other non-modified image. Thus, the X-ray information is extended into the spatial content. As an advantage, only one X-ray image is needed which means less X-ray exposure for the subject.

    摘要： A method for viewpoint selection assistance in free viewpoint video generation includes: executing acquisition processing that includes acquiring three-dimensional information with respect to a subject on a field by using a plurality of cameras placed around the field; executing first identification processing that includes identifying a path of a ball for a predetermined period based on the three-dimensional information; executing second identification processing that includes identifying at least one player located within a predetermined distance from a position of the ball for a predetermined duration of time or longer in the predetermined period; executing setting processing that includes setting, as a video output range, a range containing both of the path of the ball and a path of the at least one player; and executing generation processing that includes generating video for the range set by the setting processing.
