A localization device assisted with augmented reality and a localization method thereof are provided. The localization device includes a subject object coordinate generating unit, a relative angle determining element and a processing unit. The subject object coordinate generating unit selects at least three subject objects outside the localization device and obtains at least three subject object coordinate values of the at least three subject objects. The relative angle determining element determines at least two viewing angle differences between any two of the at least three subject objects. The processing unit generates a location coordinate value of the localization device according to the at least two viewing angle differences and the at least three subject object coordinate values.

A communication system for supporting a positioning operation within a specific area includes a system server and a communication device. The system server receives training location data corresponding to m training locations, wherein m is a natural number greater than 1, and obtains a first set and a second set of parameters according to m sets of training location data respectively corresponding to m training locations by way of conversion. The communication device downloads a part or an entire of the first set and the second set of parameters from the system server, establishes a positioning function according to the downloaded part or entire of the first set and the second set of parameters, determines to-be-positioned location data of a to-be-positioned location, and substitutes the to-be-positioned location data into the positioning function to generate positioning result data corresponding to the to-be-positioned location of communication device.
