一種室內定位方法及其系統，該方法包含以下步驟：先設置複數信標於一室內空間，並以非同步方式發佈訊號。將該室內空間畫分為複數子區域，再逐一子區域進行一訓練階段：利用一定位單元收集發自信標之訊號，取得各子區域之訊號識別值。再來，進行一追蹤階段：於該室內空間中之未知位置利用該定位單元收集發自信標之訊號並與訓練階段所得訊號識別值進行比對。求出訊號值最鄰近之複數個定位單元，而得一評估位置。
An indoor localization method is implemented using an indoor localization system that includes beacons in an indoor space and each periodically transmitting a localization signal, a radio badge receiving the localization signals, and a host coupled to the beacons and the radio badge. The beacons transmit the localization signals asynchronously. The indoor localization method includes a training phase and a tracking phase. During the training phase, signal vectors are formed from the localization signals received by the radio badge, and a signal ID value is generated from the signal vectors. During the tracking phase, signal vectors are formed from the localization signals received by the radio badge at a current location. An estimated position of the radio badge is obtained using the signal vectors of the tracking phase and the signal ID values.
