Abstract
Methods and systems for using barcodes to determine item dimensions are disclosed herein. An example method includes a scanner identifying a barcode in an image of an object, and determining a datum associated with the barcode. A physical feature of the object located outside of the barcode is identified. A comparison of the datum associated with the barcode to the physical feature is made; and, in response, at least one dimension of the object is determined.
Claims30
A method for improper object detection using a barcode reader, the method comprising:
- identifying a barcode in an image of an object;
- determining a datum associated with the barcode;
- identifying a visual feature of the object located outside of the barcode;
- comparing the datum associated with the barcode to the visual feature and, in response, determining at least one dimension characteristic of the object;
- and
- in response to determining the at least one dimension characteristic, comparing the at least one dimension characteristic to at least one reference dimension characteristic of the object, and in response to a mismatch between the at least one dimension characteristic and the at least one reference dimension characteristic, determining an improper object detection event has occurred;
- wherein the visual feature comprises one or more of a physical feature or a printed feature.
A method for improper object detection, and developing a reference dimension model for an object, the method comprising:
- a) identifying a barcode in an image of an object;
- b) determining at least one datum associated with the barcode;
- c) identifying a plurality of visual features of the object, each visual feature located outside of the barcode, wherein the plurality of visual features comprises physical features or printed features;
- d) comparing the at least one datum associated with the barcode to the visual features and determining a plurality of dimension characteristics for the object;
- e) storing the plurality of dimension characteristics as the reference dimension model;
- and
- f) determining that an improper object detection event has occurred by:
- (i) comparing a dimension characteristic of the plurality of dimension characteristics to a dimension characteristic of a detected object, and (ii) determining a mismatch between the dimension characteristic of the plurality of dimensions characteristics and the dimension characteristic of the detected object.
An electronic device for improper object detection using a barcode reader, electronic device comprising a housing including a controller, wherein the controller is configured to:
- identify a barcode in an image of an object;
- determine a datum associated with the barcode;
- identify a visual feature of the object located outside of the barcode;
- compare the datum associated with the barcode to the visual feature and, in response, determine at least one dimension characteristic of the object;
- and
- in response to the determination that the at least one dimension characteristic, compare the at least one dimension characteristic to at least one reference dimension characteristic of the object, and in response to a mismatch between the at least one dimension characteristic and the at least one reference dimension characteristic, determine that an improper object detection event has occurred;
- wherein the visual feature comprises one or more of a physical feature and/or a printed feature.
