A camera-based barcode reader captures an image, determines a region of interest of a barcode within the image, and generates a barcode image from the region of interest. The camera-based barcode reader aligns each of multiple horizontal regions within the barcode image to a reference horizontal region within the barcode image. The alignment of a horizontal region includes (i) determining a set of alignment parameters to apply to the horizontal region based on a comparison of the reference horizontal region to the horizontal region when adjusted to different combinations of alignment parameters and (ii) adjusting the horizontal region according to the set of alignment parameters for that horizontal region. After aligning the barcode image, the camera-based barcode reader decodes the barcode from the barcode image.

Efficient parallel barcode subpixel alignment

Embodiments herein describe a 2D barcode that overlays text or graphics (e.g., another barcode) while permitting the underlying text or barcode to be read by a user or a barcode scanner. Further, the embodiments herein describe techniques for separating the overlaid 2D barcode from the underlying text or graphics so that the barcode can be identified and decoded. In one embodiment, the blocks forming the 2D barcode are printed (or displayed) using a shade of a color while the text or graphics are printed (or displayed) using a darker shade of that same color.

2D barcode overlays

Embodiments herein describe design techniques for generating a fingerprint for a shipping label using symbols or bit segments. These symbols or bit segments can be read using lower resolution cameras at greater distances than 1D or 2D barcodes in the shipping labels. In one embodiment, a label designer identifies blank zones in the design of a shipping label and selects symbols to place in those zones. The label designer can select random types of symbols and random sizes for those symbols. When reading the shipping label, a CV system can identify the symbols and their sizes and generate the fingerprint. In another embodiment, the label designer places bit segments in the identified blank zones. The CV system can then read the blank zones in a predefined order and merge the bits segments to form a digital fingerprint for the shipping label.

Package identification using graphics on shipping labels

Wearable scanners or readers may be mounted to and operated from at least one extension of the human body, such as a portion of a hand or wrist of a user. The wearable scanners or readers may include one or more manual or automatic actuators for initiating a scanning or reading of a marking on an object. Such actuators may be worn about the portion of the hand or wrist of the user, including within a palm of the hand, or in a ring-like device surrounding at least one finger of the hand. Additionally, the wearable scanners or readers may include optical elements configured to capture images in one or more directions or along one or more axes, and may further include any type of display elements (e.g., touchscreens, LED or LCD displays, or electrophoretic displays) formed in substantially flat or curved shapes.
