User-guided object identification

摘要

A user attempting to obtain information about an object can capture image information including a view of that object, and the image information can be used with a matching or identification process to provide information about that type of object to the user. In order to narrow the search space to a specific category, and thus improve the accuracy of the results and the speed at which results can be obtained, the user can be guided to capture image information with an appropriate orientation. An outline or other graphical guide can be displayed over image information captured by a computing device, in order to guide the user in capturing the object from an appropriate direction and with an appropriate scale for the type of matching and/or information used for the matching. Such an approach enables three-dimensional objects to be analyzed using conventional two-dimensional identification algorithms, among other such processes.

主权项

1. A computing device, comprising:
at least one processor; a camera; a display screen; and a memory device including instructions that, when executed by the at least one processor, cause the computing device to:
display image information on the display screen, the image information including a current view of an object as acquired using the camera;display a plurality of orientation guides on the display screen;cause prompt information to be displayed concurrently with the plurality of orientation guides, the prompt information including a request to a user of the computing device for selecting one of the plurality of orientation guides;detect one or more types of input gestures with respect to the displayed prompt information;adjust a subset of the plurality of orientation guides based at least in part on the detected one or more types of input gestures;receive a selection of at least one adjusted orientation guide of the subset of the plurality of orientation guides;cause the selected at least one adjusted orientation guide to be displayed concurrently with the image information on the display screen;detect a change in position of the computing device with respect to the object;cause an image of the object to be captured by the camera based at least in part on the change in position detected, the image being captured based at least in part on an orientation and size of a representation of the object in the image information being similar to an orientation and size of the selected at least one adjusted orientation guide;determine a type of object in a category that corresponds to at least a portion of the representation of the object in the image information; andprovide identifying information for the object related to the determined type of object in the category.
