    Abstract: This disclosure is directed to an item-identifying cart that may be utilized by a user in a materials handling facility to automatically identify items that the user places in their cart, and update a virtual shopping cart to include items taken by the user. The mobile cart may include four capture assemblies that are disposed proximate to each of the four corners of a basket of the cart, and oriented such that their respective optical axes are directed towards an interior of a perimeter of the top of the basket, and above the top of the basket. The capture assemblies may include proximity sensors that are used to detect movement above the top of the basket, LEDs that illuminate items, and cameras that generate image data representing the items as they are placed in, or removed from, the cart.

    Abstract: A tag with sufficient variability is generated. The tag facilitates quick location and processing within a facility. During generation, a matrix representative of a possible tag may be tested for sufficient variability. A two-dimensional matrix representing the possible tag may include different bit values at different positions. A variability metric of the matrix is performed to check the variability between adjacent elements of the matrix. This variability metric of the matrix is then compared against a variability threshold value. If the variability metric of the matrix falls below the threshold value, the matrix is flagged as unusable. If the variability metric of the matrix exceeds the threshold value, the matrix can be used to generate a tag with sufficient variability. Once generated, the tag can be presented and affixed to an item or object to help identify and locate the item within the facility.

    Abstract: Tags comprising marks arranged in a predetermined pattern are applied to an item. The marks are made with an ink that fluoresces under infrared (IR) light. A camera with a filter acquires an image of the light emitted by the fluorescence of the ink. This image is processed to determine a portion of the image in which the tag is located. Once located, that portion is processed to rectify and align the tag. This rectified image is then processed to read out tag data that is encoded by the arrangement of marks. The tag data may then be used to identify the item, designate shipping information, and so forth.

    Abstract: This disclosure is directed to item-identifying carts that may be utilized by users in material handling facilities to automatically identify items that the users place in their carts as they move around the material handling facilities. In addition, these carts may automatically determine the outcome of respective events that occur with respect to these identified items. For example, the carts may be configured to identify one or more items that are placed into or removed from the cart, and thereafter determine one or more actions taken with respect to the identified items and a quantity of the items involved.

    Abstract: This disclosure describes using trained classifiers and additional data to identify items placed into a tote. The techniques may use a first classifier on image data representing an item to determine a region associated with a barcode of the item and may use one or more second classifiers to analyze the region for determining a candidate barcode. The techniques may then determine whether the candidate barcode corresponds to the actual barcode of the item. If so, the techniques may update a virtual cart associated with a user account to indicate the acquisition of the item. If not, then the techniques may use the additional data for identifying the item. For example, the techniques determine a current location of a tote for determining items that are within a threshold distance of the location and may use this information, along with the candidate barcode, to identify the item placed into the tote.

    Abstract: A tag comprises cells represented by marks, such as white and black, arranged in a predetermined pattern. Reference cells are used to determine the edges of the tag and orientation, while others are used to encode data and error correction data. During processing, a tag is detected based on a variability metric within a given region of an image exceeding a threshold value. Once detected, the orientation of the tag is determined using the reference cells. Confidence values, indicative of a likelihood that the cell is a particular cell value, such as white or black, are determined for each cell in a first set of cell values. If the first set is invalid, the cell values for a set of lowest confidence cell values are inverted to produce a second set of cell values. The second set is tested, and if valid, is used to produce output data.

    Abstract: An ink that is detectable using infrared (IR) light may be used to apply machine readable codes, such as a barcode. The indicia, once applied, may be either invisible or difficult to detect with visible light, such as with the human eye. The ink may include one or more materials such as titanium dioxide (TiO2), particles of acrylonitrile butadiene styrene (ABS), metals, and so forth. These materials may be used to enhance one or more of the reflectivity to IR light or the fluorescence of the ink under IR light. The fluorescent ink may be deposited in a single pass, or as part of a two-pass process in which a reflective substrate, such as a resin with encapsulated TiO2, is applied and then the fluorescent ink is deposited atop the substrate. The markings are machine readable even when overprinting markings that are readable under visible light.
