基于电磁信号的室内定位系统设计与实现

With the popularity of mobile intelligent terminals and the rapid development of mobile Internet, location-based services and applications appeared in large numbers. Low-cost and high-precision indoor positioning solution has become a new hotspot. Wi-Fi location fingerprinting is a main techniques to solve indoor positioning problem, and indoor positioning based on magnetic field is a hot research field in recent years. Wi-Fi location fingerprintint identify coordinate with the type and strength of received signal, according to the received signal strength information to determine the location of person. Magnetic location treat magnetic strength vector as base sample, using particle filter technology to simulate location of person. This perpar proposes a hybrid algorithm based on Wi-Fi and magnetic technology which enhances the accuracy.
