Abstract
Features described herein generally relate to locating objects in a scene using optical pattern recognition. Images of a scene that include objects are captured and optical patterns associated with the objects are detected and decoded. Code data for the optical patterns can be matched to search parameters matching input search criteria. The images can be displayed along with a graphic that overlays at least one of the images to indicate that an object matching the search criteria is depicted in the scene.
Claims20
A system comprising:
- a camera;
- and
- a computer readable storage medium storing instruction that, when executed by one or more processors, cause the system to perform operations comprising:
- capturing, using the camera, a plurality of images depicting a plurality of optical patterns in a scene, each optical pattern of the plurality of optical patterns corresponding to an object of a plurality of objects in the scene;
- decoding, within the plurality of images, the plurality of optical patterns in the scene to obtain a plurality of code data for the plurality of optical patterns;
- extracting, from a database and based on the plurality of code data, a plurality of entries, each entry of the plurality of entries corresponding to a respective object of the plurality of objects;
- accessing a search parameter, the search parameter derived from search criteria provided as input using a graphical user interface page, wherein the search parameter comprises a barcode corresponding to the search criteria;
- comparing the barcode to barcodes included in sets of data associated with the plurality of entries;
- ascertaining that the search parameter matches particular barcodes of the barcodes;
- and
- in response to ascertaining that the search parameter matches the particular barcodes, displaying, on a display, a preview image of a portion the scene and a graphical overlay that overlays the preview image, the graphical overlay comprising:
- (i) a first graphic that distinguishes an optical pattern depicted by the preview image and associated with the particular barcodes from another optical pattern depicted by the preview image;
- (ii) a second graphic that provides an indication of a quantity of optical patterns depicted by the preview image that are associated with the particular barcodes;
- (iii) a third graphic that identifies optical patterns depicted by the preview image that are not associated with the particular barcodes, wherein the first graphic is different from a color of third graphic;
- (iv) a fourth graphic that provides a notification that optical patterns that are depicted by the preview image and associated with the particular barcodes have been found;
- (v) a slide of a graphical carousel that comprises a plurality of slides, wherein the slide includes an image of an object associated with the optical pattern, text describing the object, and code data representing the optical pattern;
- and (vi) a button that, when toggled, causes the graphical carousel to overlay the preview image.
