Abstract: The information querying method is provided. The query image is received via a login gateway among the serving gateways. At least one of query description of the query image is generated. At least one first candidate object is sifted from a plurality of candidate objects according to a location of the login gateway and locations of candidate objects, wherein a plurality of candidate descriptions of each of the candidate objects are recorded in a database. The at least one query description of the query image is compared with the candidate descriptions of the at least one first candidate object, so as to obtain the target object from the candidate objects according to similarity level between the at least one query description and the candidate descriptions of the at least one first candidate object.

Abstract: An object recognition method and an object recognition apparatus using the same are provided. In one or more embodiments, a real-time image including a first object is acquired, and a chamfer distance transform is performed on the first object of the real-time image to produce a chamfer image including a first modified object. Preset image templates each including a second object are acquired, and the chamfer distance transform is performed on the second object of each preset image template to produce a chamfer template including a second modified object. When the difference between the first modified object and the second modified object is less than a first preset error threshold, the object recognition apparatus may operate according to a control command corresponding to the preset image template.
