  • Patent number: 8847947
    Abstract: A system for tolerancing geometrical templates upgrades the geometrical template to include a unique identifier and index corresponding to each sub-feature of the template. The upgraded template is associated to a set of 3D annotations and the association is stored in a catalog which uses the unique identifier as an index. Upon instantiation of the geometrical template, a list of corresponding tolerance templates are retrieved and displayed for selection, and a selected tolerance template is then instantiated onto the geometrical template.

  • Patent number: 8847951
    Abstract: Methods and systems permit automatic matching of videos with images from dense image-based geographic information systems. In some embodiments, video data including image frames is accessed. The video data may be segmented to determine a first image frame of a segment of the video data. Data representing information from the first image frame may be automatically compared with data representing information from a plurality of image frames of an image-based geographic information data system. Such a comparison may, for example, involve a search for a best match between geometric features, histograms, color data, texture data, etc. of the compared images. Based on the automatic comparing, an association between the video and one or more images of the image-based geographic information data system may be generated. The association may represent a geographic correlation between selected images of the system and the video data.
