    摘要: A viewport lens displays registered information registered using embedded data. An image capture device captures an image from the substrate that includes embedded data. The embedded data in the captured image is decoded to create information regarding the substrate, such as location, orientation, or a label. Based on the information regarding the substrate, information is generated that is registered with the substrate. In one embodiment, the information is registered with the substrate by optically combining the generated information with substrate information in a viewport lens.

    摘要: A system and method for generating information based on decoded embedded data from a substrate is implemented by reading embedded data from a substrate, decoding the embedded data to determine registration of the substrate relative to a reference in an apparatus, and developing and presenting human-sensible information based on the registration information. In one embodiment, the human-sensible information is visual information registered with the substrate. The human-sensible information may also comprise, for example, tactile, audible, or other sensory information.

    摘要: An angular orientation of a lattice image pattern is found by forming a composite image of superimposed portions of a lattice image by aligning centroids of a lattice element in each portion, and determining a lattice axis from a line fit through centroids of lattice elements in the composite image. The composite image is formed by selecting a seed pixel, finding a local minimum near the seed pixel and then finding a centroid based on the local minimum. From the centroid, it is determined whether the glyph centroid has sufficient contrast to be included in the composite image. The composite image is formed by superimposing subsamples of the lattice image based on glyph centroids. The composite image is then analyzed to determine a lattice axis through centroids in the composite image, and determining a quadrant image based on the lattice axis.
