| Summary: | 碩士 === 逢甲大學 === 資訊工程學系 === 105 === Along with the rapid development of smart application, the requirement for accuracy of indoor positioning industrially. To enhance accuracy of indoor positioning, this study proposed to utilize multiple equipment installed in the same positions to filter positioning error to reduce instability caused by receiving signals. Meanwhile, we also proposed a filtering algorithm referring to absolute position and moving direction information and prediction algorithm. When values are out of reasonable range, it can adopt prediction results to conduct calibration. From the experimental results it is known the proposed method is effective to enhance the accuracy of indoor positioning.
