Method of positioning and electronic apparatus using the same

摘要

An electronic apparatus includes a selection unit, a storage unit and a processing unit. The selection unit and the storage unit are coupled to the processing unit. The selection unit selects a first reference point proximate to the electronic apparatus. The storage unit stores a plurality of second locations of a plurality of second reference points. The processing unit executes a single-point distance measurement between the electronic apparatus and a first location of the selected first reference point, provides the electronic apparatus auxiliary positioning information by selecting the second locations stored in the storage unit and generates a speculative location of the electronic apparatus by further computing the results of the single-point distance measurement and the auxiliary positioning information.

1. An electronic apparatus comprising:
a selection unit for selecting a first reference point proximate to the electronic apparatus; a storage unit for storing a plurality of second locations of a plurality of second reference points; and a processing unit coupled to the selection unit and the storage unit; wherein the processing unit conducts single-point distance measurement between the electronic apparatus and a first location of the selected first reference point, provides the electronic apparatus auxiliary positioning information by selecting the second locations stored in the storage unit and generates a speculative location of the electronic apparatus by further computing the result of the single-point distance measurement and the auxiliary positioning information; wherein the first location and the second locations are three-dimensional coordination including X, Y, and Z axes; wherein the single-point distance measurement includes the processing unit computing a first geometric distance between the first reference point and the electronic apparatus; wherein the auxiliary positioning information includes the processing unit respectively computing a plurality of second geometric distances between the first reference point and the second reference points.
