摘要： A method generates a three-dimensional map of a region from successive images captured from different camera poses. The method includes a camera capturing images of the region; designating a subset of captured images as a set of keyframes each having respective sets of image position data representing image positions of landmark points detected as feature points in that image; for a newly captured image, generating a camera pose prediction; selecting an ordering of the landmark points; detecting whether an image region of the new image approximately matches an expected image position of a landmark point based on the predicted camera pose by detecting whether the image region is substantially identical to the image information associated with that landmark point; and refining the pose prediction from the detecting step. The selecting includes performing a statistical test on the landmark points and selecting the ordering according to the statistical test results.

摘要： A method of rendering an image based upon a first stereoscopic image comprising a pair of images is provided. The method includes generating a virtual three-dimensional model of the scene depicted in the first stereoscopic image responsive to distances derived from the first stereoscopic image, detecting one or more free edges in the three dimensional model, and generating one or more textures for the virtual three-dimensional model from at least one of the pair of images of the first stereoscopic image. The method also includes applying at least one texture to a respective part of the three dimensional model, and rendering the virtual three dimensional model from a different viewpoint to that of the first stereoscopic image. Rendering the virtual three dimensional model comprises modifying a transparency of rendered pixels of an applied texture as a function of the pixel's distance from that free edge.

摘要： Aspects of the technology encompass image encoding, which includes generating image content according to a viewpoint defined by image viewpoint data. Successive output images are generated such that each output image includes image content generated according to one or more viewpoints, and encoding metadata associated with each output image which indicates each viewpoint relating to image content contained in that output image, and which defines which portions of that output image were generated according to each of those viewpoints. An image display method for generating successive display images from successive input images is also provided, which includes re-projecting portions of each input image to form a respective display image, according to any differences between a desired display viewpoint and a particular viewpoint defined for that portion by metadata associated with a respective input image. The metadata indicating viewpoints relating to image content contained in the respective input images.

摘要： A display method using a display operable to display an image to a viewer is provided. The method includes detecting an initial position and/or orientation of an image view. Foreground portions of an image are rendered according to the detected initial position and/or orientation. Background portions of the image are rendered according to the detected initial position and/or orientation, at an image rendering rate. The following are performed at an image display rate higher than the image rendering rate: (i) detecting a current position and/or orientation of the image view; (ii) re-projecting the background portions of a most recent image according to any differences between the initial position and/or orientation and the current position and/or orientation of the image view; and (iii) combining the foreground portions and the re-projected background portions to generate an image for display.

摘要： A method generates an image for display by deriving an expected depth of field for the image and by generating the image for display by the display device by applying a blurring function. The expected depth of field is derived with respect to a point of focus in the image, in response to lighting conditions of the environment represented by the image. The blurring function is applied to simulate the expected depth of field of the image by blurring as a function of apparent spatial depth within the image. The degree of blurring applied to a closer depth region, in an apparent depth direction, to the point of focus is lower than the degree applied to a further depth region from the point of focus. Variation of the blurring function with respect to depth separation from the point of focus depends upon the expected depth of field.
