英文摘要 | In this paper, we introduce an indoor-positioning system using ultra-wideband radio signals. To enhance the accuracy of indoor positioning, in our study, we propose to use multiple anchors installed at the same locations to filter positioning error to reduce the instability caused by receiving signals. In addition, we also propose a filtering algorithm referring to the absolute position and moving-direction information of the positioned object and a prediction method to predict the next position of the positioned object based on previous coordinates. When the error values are out of the acceptable range, it can adopt prediction results to conduct calibration using a control object. From the experimental results, our proposed method is effective in enhancing the accuracy of indoor positioning compared to other related works. |
