摘要： Spherical rotation is described for encoding a video that has a wide field of view, such as a spherical or hemispherical video. One example relates to receiving encoded video including rotation orientation metadata, decoding the video, extracting the rotation orientation metadata, rotating the decoded video based on the rotation orientation metadata, generating a view of the rotated decoded video, and buffering the generated view for display.

摘要： An apparatus for building a map is disclosed. The apparatus for building a map according to the present invention includes a data collection unit configured to separately collect vector data and raster data, a vector data processing unit configured to generate ground-truth images of a previously set size by processing the vector data, a raster data processing unit configured to generate divided raster images of the set size by processing the raster data, and a polygon generation unit configured to generate predicted polygons through machine learning of the ground-truth images and the divided raster images and generate polygons which can be applied to map building based on the raster data on the basis of the predicted polygons and the ground-truth images.

摘要： The invention relates to a method for modelling a scene from a plurality of maps representative of depth, each map representative of depth being associated with a view of the said scene according to a particular viewpoint (410, 420). To optimize the fidelity and precision of the scene modelling, the method comprises the following steps: - generating, for each map representative of depth, a surface (31, 32) representative of the said depth map in world space; - estimating a volume bounding all surfaces (31, 32) generated, the said bounding volume being discretised into a plurality of voxels; - associating attributes representative of transparency with the said voxels of the bounding volume; and - generating a resulting surface according to the attributes representative of transparency associated with the said voxels. The invention also relates to a device for processing the data representative of the corresponding depth.

摘要： Techniques are described for generating a three dimensional (3D) object from complete or partial 3D data. Image data defining or partially defining a 3D object may be obtained. Using that data, a common plane facing surface of the 3D object may be defined that is substantially parallel to a common plane (e.g., ground plane). One or more edges of the common plane facing surface may be determined, and extended to the common plane. A bottom surface, which is bound by the one or more extended edges and is parallel with the common plane, may be generated based on the common-plane facing surface. In some aspects, defining the common plane facing surface may include segmenting the image data into a plurality of polygons, orienting at least one of the polygons to face the common plane, and discarding occluding polygons.

摘要： The present disclosure relates to a method and apparatus for coding a plurality of 2D pictures representative of picture data of an omnidirectional video into a bitstream, at least one of the 2D picture of said plurality of 2D pictures is predictive-coded using at least one 2D reference picture, characterized in that the method comprises:
- when at least one coded 2D picture of said plurality of 2D pictures is used as reference for predictive-coding;
- packing a decoded version of each of all the coded 2D pictures into a composite frame leaving room between said decoded versions and between the border of said composite frame and some of said decoded versions; and
- spatially extending each of said decoded version independently of each other.
