摘要
为了实现三维状态下LANDMARC系统的高精度定位,采用RFID室内定位算法,提出具有矫正因子的三维矫正定位算法,同时结合三角定位技术,将三维矫正定位算法应用于三维空间中,确保提高定位精度。通过Matlab仿真可以看出,提出的三维矫正定位算法应用于空间定位,计算误差降低了50%,提高了系统的可靠度。并且克服了LANDMARC系统硬件成本高,需要较多参考指标的不足。
In order to realize the three-dimensional state under the LANDMARC system of high precision positioning by RFID indoor location algorithm, put forward a correction factor of three-dimensional correction algorithm, and combining with the triangulation technology 3D correction localization algorithm is applied in three-dimensional space, to ensure the improvement of the positioning accuracy. The Matlab simulation shows that the proposed method is applied to the spatial location, and the calculation error is reduced by 50%, which improves the reliability of the system. And overcome the LANDMARC system hardware cost is high. need more reference index.
