Association method and association apparatus to obtain image data by an imaging apparatus in a view area that is divided into multiple sub-view areas
First Claim
1. A method for reading radio frequency identification (RFID) tags on commodities, comprising:
- acquiring, by a system comprising a processor, image data representative of an image in a view area of an imaging apparatus;
dividing the view area into three-dimensional sub-view areas, wherein the three-dimensional sub-view areas are larger than a size of an RFID tag of a commodity of the commodities;
acquiring an attribute information set of the commodities in a sub-view area of the three-dimensional sub-view areas using beam scanning;
establishing a correspondence between the attribute information set and the image corresponding to the three-dimensional sub-view areas;
acquiring, in response to a presence of a group of RFID tags corresponding to a group of the commodities in one of the three-dimensional sub-view areas, respective distances between the group of the commodities and a beam emitting position; and
presenting, in the image, at least some of the attribute information set of the commodities, wherein the presenting comprises indicating the respective distances between the group of the commodities and the beam emitting position.

Abstract
An association relating to the field of communications is enabled. A method comprises: acquiring image data in a view area of an imaging apparatus; dividing the view area into sub-view areas; acquiring an attribute information set of at least one object in any one sub-view area through beam scanning; establishing a correspondence between the attribute information set and image data corresponding to the one sub-view area; and acquiring, in response to that the attribute information set comprises attribute information of multiple objects, distance related information between the multiple objects and a beam emitting position. An accurate correspondence can be established between an object in a view area of an imaging apparatus and attribute information of the object, and with multiple objects, distance related information between the objects and a beam emitting position is acquired, which helps to further determine a correspondence between each object and corresponding attribute information.
