摘要： There is disclosed an apparatus and method for combining three or more texture maps 200–208 together to generate a single, combined texture map 220. The texture maps are repeatedly combined together in pairs, with each pair generating a larger texture map for subsequent combination with another texture map, until only one texture map remains containing all of the original texture maps.

摘要： In an image processing apparatus 20 an input sequence 130 of video images is processed to determine the different positions and orientations at which the images were recorded in an efficient and accurate manner. A subset of the input images are selected as keyframes to form a sequence 250 of keyframes. Respective triples of keyframes having different, non-overlapping positions in the sequence 250 are selected and processed to determine the relative positions and orientations at which the keyframes in each triple were recorded to form respective sets of keyframes. The positions and orientations of keyframes between the keyframes in each triple are then calculated to form expanded sets of keyframes 266, 276, 286. The sets are further expanded by calculating the positions and orientations of keyframes which lie between sets in the sequence 250. The sets are merged by calculating the relationship between the coordinate systems in which the positions and orientations of the keyframes in each set are defined. During the processing, the positions and orientations calculated for keyframes in a set are adjusted to optimise the calculated solutions. This is performed in stages, considering at each stage a different window 270 of the keyframes and performing processing to minimise the error associated with the keyframes in the window. The window is moved sequentially through the keyframes so that every keyframe in a set is considered at least once.

摘要： To generate a 3D computer model of a subject object 210, images 300-316, 380-384 of the subject object are recorded from different viewing positions and directions. The image data is processed to generate a plurality of sets of images, each set containing images having registered imaging positions and directions. A preliminary 3D computer model 390 is generated using the images from a first of the sets such that the position and orientation of the preliminary 3D computer model 390 is registered with the images in the set. The imaging positions and directions of the images in the first set are then registered with the imaging positions and directions of the images in each other respective set. This is done by projecting the preliminary 3D computer model 390 into images from each other set, and changing the relative position and orientation of the preliminary 3D computer model 390 and images to align the silhouette of the projected 3D computer model with the silhouette of the imaged subject object in the images. A refined 3D computer model of the subject object is generated using images from the different sets which are registered.

摘要： In a computer processing apparatus 3002, a number of depth maps 3200-3270 of a subject object 3300 are processed to generate a 3D computer model of the subject object. The points in each depth map are connected to give a 2D mesh, and each 2D mesh is then projected into 3D space in dependence upon the depths of the points in the mesh, thereby giving a 3D mesh 3610. Side faces for each edge of the 3D mesh are added extending away from the depth map, thereby generating a respective polyhedron 3600 for each depth map. The 3D computer model of the subject object is generated by calculating the intersections of the polyhedra.

摘要： A plurality of texture maps for a 3D computer model of an object are generated by processing images of the object, data defining the computer model, and data defining the relative positions and orientations of the images and computer model. A respective texture map is generated for the viewing position and direction of each image. Each texture map stores texture data for all parts of the computer model which are visible from the associated viewing position and direction and also texture data for all invisible parts of the computer model. Each texture map therefore stores texture data that can be used for rendering accurate images of the 3D computer model over a wide range of viewing positions and directions.

摘要： A texture map (188) for texturing a polygon mesh 3D computer model (150) during rendering is generated by defining a respective triangle within the texture map for each triangle in the polygon mesh to create a texture coordinate map (170), and allocating image data to each defined triangle. To generate the texture coordinate map, the triangles in the polygon mesh are processed to generate a plurality of lists, each list identifying adjacent triangles in the mesh having shapes which can be packed into strips (173-179) of the texture coordinate map without significant shape distortion. The triangle lists are then packed into the texture coordinate map strips. No padding is defined between triangles in the same list, only between triangles of different lists. Image data is allocated to each triangle.

摘要： An apparatus is disclosed for generating frequency component image data representative of image information of a plurality of different spatial frequencies of an image of at least part of a subject from a predefined view. A receiver receives a plurality of images comprising image data representative of a subject from a plurality of view points. For each of a plurality of received images, frequency component image data representative of image information of a plurality of different spatial frequencies within images received by the receiver is determined, and projections of the frequency component image data projected to a predefined view are also determined. Visibility data indicative of the relative visibility of portions of the surface of a subject from viewpoints is then determined. Portions of projections of frequency component image data are associated with the visibility data, and the visibility data associated with portions of projections are utilized to determine frequency component image data representative of frequency image information of an image of a subject from a predefined view.

摘要： In a computer processing apparatus 2, a 3D computer model comprising a polygon mesh 500 representing the visual hull of an object 300 is generated by processing images of the object recorded at different positions and orientations to back-project the silhouette of the object in each image to give a respective cone which constrains the volume of 3D space occupied by the object. To remove concave and convex artefacts 510 in the polygon mesh 500, the polygon mesh is projected into each image to give a respective reference silhouette for each image. A change is made to at least one edge or vertex in the polygon mesh to give a refined polygon mesh, which is then projected into each image. The resulting silhouette in each image is tested against the corresponding reference silhouette. If the silhouette of the refined polygon mesh is the same as each reference silhouette, to within an allowable tolerance, then the changed edge or vertex is allowed in the polygon mesh, otherwise the polygon mesh is returned to its previous state. This processing to change and test the polygon mesh is carried out a number of times. Artefacts are removed from the polygon mesh because their removal does not make the polygon mesh inconsistent with the reference silhouettes. Parts of the polygon mesh representing actual features of the object are not changed because such a change causes the polygon mesh to become inconsistent with at least one reference silhouette and therefore such a change is rejected.
