| Summary: | With the rapid development of LBS (Location-based Service), the demand for commercialization of indoor location has been
increasing, but its technology is not perfect. Currently, the accuracy of indoor location, the complexity of the algorithm, and the cost
of positioning are hard to be simultaneously considered and it is still restricting the determination and application of mainstream
positioning technology. Therefore, this paper proposes a method of knowledge-based optimization of indoor location based on low
energy Bluetooth. The main steps include: 1) The establishment and application of a priori and posterior knowledge base. 2) Primary
selection of signal source. 3) Elimination of positioning gross error. 4) Accumulation of positioning knowledge. The experimental
results show that the proposed algorithm can eliminate the signal source of outliers and improve the accuracy of single point
positioning in the simulation data. The proposed scheme is a dynamic knowledge accumulation rather than a single positioning
process. The scheme adopts cheap equipment and provides a new idea for the theory and method of indoor positioning. Moreover,
the performance of the high accuracy positioning results in the simulation data shows that the scheme has a certain application value
in the commercial promotion. |
