Abstract: A method of generating a 3D reconstruction of a scene, the scene comprising a plurality of cameras positioned around the scene, comprises: obtaining the extrinsics and intrinsics of a virtual camera within a scene; accessing a data structure so as to determine a camera pair that is to be used in reconstructing the scene from the viewpoint of the virtual camera; wherein the data structure defines a voxel representation of the scene, the voxel representation comprising a plurality of voxels, at least some of the voxel surfaces being associated with respective camera pair identifiers; wherein each camera pair identifier associated with a respective voxel surface corresponds to a camera pair that has been identified as being suitable for obtaining depth data for the part of the scene within that voxel and for which the averaged pose of the camera pair is oriented towards the voxel surface; identifying, based on the obtained extrinsics and intrinsics of the virtual camera, at least one voxel that is within the fie

Abstract: A system for characterising surfaces in a real-world scene, the system comprising an object identification unit operable to identify one or more objects within one or more captured images of the real-world scene, a characteristic identification unit operable to identify one or more characteristics of one or more surfaces of the identified objects, and an information generation unit operable to generate information linking an object and one or more surface characteristics associated with that object.

Abstract: A content generation system for generating content for display including one or more objects to be rendered, the system comprising an element defining unit operable to define a plurality of virtual elements, a parameter setting unit operable to set one or more parameters associated with each of the plurality of virtual elements, and a content generating unit operable to generate content for display using the plurality of virtual elements and corresponding parameter values, wherein the parameter setting unit is operable to set the one or more parameters in accordance with the output of a machine learning algorithm adapted to determine appropriate parameters for the plurality of virtual elements so as to simulate an object to be rendered.

Abstract: A digital model repair method includes: providing a point cloud digital model of a target object as input to a generative network of a trained generative adversarial network ‘GAN’, the input point cloud comprising a plurality of points erroneously perturbed by one or more causes, and generating, by the generative network of the GAN, an output point cloud in which the erroneous perturbation of some or all of the plurality of points has been reduced; where the generative network of the GAN was trained using input point clouds comprising a plurality of points erroneously perturbed by said one or more causes, and a discriminator of the GAN was trained to distinguish point clouds comprising a plurality of points erroneously perturbed by said one or more causes and point clouds substantially without such perturbations.

Abstract: A system for adjusting the pose of a camera relative to a subject in a scene is provided. The system comprises a camera operable to capture images of a scene; an identification unit configured to identify an object of interest in images of the scene; a pose processor configured to obtain a pose of the object of interest in the scene relative to the camera; a scene analyser operable to determine, based on at least one of the obtained pose of the object of interest and images captured by the camera, a scene quality associated with images captured by the camera. A controller is configured to cause the pose of the camera to be adjusted based on a determination that the scene quality of an image captured at a current pose is less than a threshold value. A corresponding device is also provided.

Abstract: A system for providing information to a user via a heads-up display includes a first display operable to display images of a first content to the user, a gaze tracking unit operable to identify the user's gaze direction with respect to one or more elements of the first content, a content generation unit operable to generate second content for display to a user in dependence upon the identified gaze direction, and a heads-up display operable to display the second content to the user.

Abstract: A foveated rendering system for modifying content to be displayed includes a user profile obtaining unit operable to obtain a user profile comprising information about head motion and eye motion for a user, and a foveated rendering unit operable to apply a foveated rendering process to the content to be displayed in dependence upon obtained user profile information.

Abstract: A system for controlling interactions between a plurality of real and virtual robots, includes one or more real robots present in the real environment, one or more virtual robots present in a virtual environment corresponding to the real environment, and a processing device operable to control interactions between one or more of the real robots and one or more of the virtual robots, where the interactions between the real and virtual robots are dependent upon at least the positions of the one or more real robots in the real environment and the positions of the one or more virtual robots in the virtual environment.
