摘要： Systems and methods are provided for the production of seamless, geo-referenced orthographic images that can comprise a composite of two or more underlying images. Illustratively, an exemplary image processing environment comprises an image processing engine and an instruction set comprising at least one instruction to instruct the image processing engine to process data representative of two or more images. Illustratively, the two or more images can comprise data representative of correspondence points between the two or more images and the underlying area (e.g., ground control points). Illustratively, the exemplary image processing engine can identify features that the overlapping photos have in common (e.g., feature match points) and place and re-project (e.g., distort) each of the two or more images to achieve a selected balance of correct position (e.g., based on ground control points) and seamless overlap (e.g., based on feature match points) which can be composited into a single image.

摘要： Providing high frame rate image rendering using multiple image layers per frame. A plurality of image layers having different resolutions are arranged in order of increasing resolution. Beginning with the image layer having the lowest resolution, the image layer is upsampled to a resolution of a next image layer having a higher resolution. The upsampled image layer is blended with the next image layer. The upsampling and blending continues for each of the image layers to produce a blended image. The blended image is provided for display as a frame of video. Aspects of the invention produce a high-resolution composite image during animated navigation across zoom and pan states.

摘要： Described is a linear structure from motion technique that is scalable, parallelizable, treats images equally, and is robust to outliers, without requiring intermediate bundle adjustment. Camera rotations for images are estimated using feature point correspondence and vanishing points matched across the images. The camera rotation data is fed into a linear system for structure and translation estimation that removes outliers and provides output data corresponding to structure from motion parameters. The data may be used in further optimization e.g. with a final non-linear optimization stage referred to as bundle adjustment to provide final refined structure from motion parameters.

摘要： A display system includes a display alignment tracker configured track the position of a first signal in a first waveguide and the position of a second signal in a second waveguide. The display alignment tracker optically multiplexes a portion of a first signal and a portion of the second signal into a combined optical signal and measures a differential between the first signal and the second signal. The differential is used to adjust the position, dimensions, or a color attribute of the first signal relative to the second signal.

摘要： Methods, systems, and computer-readable media for reconstruction a three-dimensional scene from a collection of two-dimensional images are provided. A computerized reconstruction system executes computer vision algorithms on the collection of two-dimensional images to identify candidate planes that are used to model visual characteristics of the environment depicted in the two-dimensional images. The computer vision algorithms may minimize an energy function that represents the relationships and similarities among features of the two-dimensional images to assign pixels of the two dimensional images to planes in the three dimensional scene. The three-dimensional scene is navigable and depicts viewpoint transitions between multiple two-dimensional images.
