摘要： A multi-user augmented reality (AR) system operates without a previously acquired common reference by generating a reference image on the fly. The reference image is produced by capturing at least two images of a planar object and using the images to determine a pose (position and orientation) of a first mobile platform with respect to the planar object. Based on the orientation of the mobile platform, an image of the planar object, which may be one of the initial images or a subsequently captured image, is warped to produce the reference image of a front view of the planar object. The reference image may be produced by the mobile platform or by, e.g., a server. Other mobile platforms may determine their pose with respect to the planar object using the reference image to perform a multi-user augmented reality application.

摘要： An apparatus and method for supporting augmented reality or other computer vision applications are presented. Embodiments enable communication between natural feature and auto-focus engines to increase an engine's accuracy or decrease a processing time of the engine. An auto-focus engine may communicate a location of an auto-focus window to a natural feature detection module and/or a change in location of a previous auto-focus window to a next auto-focus window. The natural feature detection module uses the communicated information to limit an initial search area and/or to set a next tracking search window. A natural feature tracking module may communicate a changes from a previous location of a natural feature to a next location of the natural feature to an auto-focus engine. The auto-focus engine uses the change to set a next auto-focus window.

摘要： Methods, apparatuses, systems, and computer-readable media for taking great pictures at an event or an occasion. The techniques described in embodiments of the invention are particularly useful for tracking an object, such as a person dancing or a soccer ball in a soccer game and automatically taking pictures of the object during the event. The user may switch the device to an Event Mode that allows the user to delegate some of the picture-taking responsibilities to the device during an event. In the Event Mode, the device identifies objects of interest for the event. Also, the user may select the objects of interest from the view displayed by the display unit. The device may also have pre-programmed objects including objects that the device detects. In addition, the device may also detect people from the users' social networks by retrieving images from social networks like Facebook® and LinkedIn®.

摘要： A mobile station determines it elevation based on the determined position of mobile station and a database of elevation data. The determined elevation of the mobile station may be used to vertically position a computer generated graphics in an image produced by the mobile station. In one embodiment, the elevation of the mobile station is determined by obtaining the elevation of multiple positions that define an area around the mobile station and using the elevation at the multiple positions to calculate the elevation at the current position.

摘要： Various arrangements for tracking a target within a series of images is presented. The target may be detected within a first image at least partially based on a correspondence between the target and a stored reference template. A tracking template may be created for tracking the target using the first image. The target may be located within a second image using the tracking template.
