  • Patent number: 10140513
    Abstract: Method and systems for generating reference features sets for slices of a reference image. The reference features sets generated from slices enables better object recognition and/or tracking when a camera image only shows a portion of the reference image. Metadata is used to link the reference features set of the original image and of the slices together as belonging to the same object, providing hierarchical relationship information and/or spatial relationship information. An image processing function may be dynamically configured on the basis of whether an object has been successfully detected and the metadata associated with the object.

  • Patent number: 10102679
    Abstract: A method for improving the placement of virtual content in augmented reality is disclosed. A reference image of the object to be augmented is analyzed for feature density information. The placement of content is based on the at least one location adjacent to where features are concentrated. Accordingly, the chance of the content interfering with an important part of the object is lowered, and object recognition and/or tracking ability is maintained because there are sufficient features nearby the content to enable object recognition and/or tracking.

  • Patent number: 9946963
    Abstract: Disclosed herein is an improved method for providing content associated with barcodes in augmented reality in addition or in combination with providing content associated with target objects in augmented reality. The improved method advantageously provides a augmented reality client that a user may use to view the respective content associated with barcodes and target objects while in camera view to improve usability. Advantageously, the user is not unexpectedly taken out of camera view to view the content associated with the barcode and the user experience provided is consistent between barcodes and target objects. Furthermore, the improved method integrates barcodes and a visualization of the barcode within augmented reality, without disrupting the real-time augmented reality experience.

  • Patent number: 9704230
    Abstract: Methods and systems for determining augmentability information associated with an image frame captured by a digital imaging part of a user device. The determined augmentability score may then be used in the generation of feedback to the user. For example, a graphical user interface may be generated and rendered having a substantially continuous visual output corresponding to the augmentability information.

  • Publication number: 20150070347
    Abstract: Methods for providing a graphical user interface through an augmented reality service provisioning system. A panel is used as a template to enable content providers to provide configurations for a customizable graphical user interface. The graphical user interface is displayable in perspective with objects in augmented reality through the use of computer vision techniques.

  • Publication number: 20150040074
    Abstract: Methods and systems for enabling creation of augmented reality content on a user device including a digital imaging part, a display, a user input part and an augmented reality client, wherein said augmented reality client is configured to provide an augmented reality view on the display of the user device using an live image data stream from the digital imaging part are disclosed. User input is received from the user input part to augment a target object that is at least partially seen on the display while in the augmented reality view. A graphical user interface is rendered to the display part of the user device, said graphical user interface enabling a user to author augmented reality content for the two-dimensional image.

  • Publication number: 20150029222
    Abstract: Method and systems for dynamically configuring an image processing function into at least a first and second detection state on the basis of function parameters are described, wherein transitions between said detection states are determined by at least a first state transition condition and wherein said image processing function includes extracting features from an image frame, matching features with features associated with one or more target objects and estimating pose information on the basis of matched features and wherein method comprises: configuring said image processing function in a detection state on the basis of a first set of function parameter values; processing a first image frame in said first detection state; monitoring said image processing function for occurrence of said at least state transition condition; and, if said at least one state transition condition is met, configuring said image processing function in said second detection state.
