Problems solved by technology

However, affected by the complex indoor environment, spatial layout and topology changes, Wi-Fi / iBeacon signals are shielded and blocked. Therefore, the Wi-Fi / iBeacon solution needs to deploy corresponding hardware in advance, and geomagnetic positioning needs to be collected in advance and Non-collection areas cannot be well matched and positioned, which requires more procedures and energy, manpower and material resources, and increases cost input
[0004] Second, the inertial navigation system relies on inertial sensors to obtain the travel distance and direction of the mobile device. Only the inherent inertial sensors (accelerometers, gyroscopes, etc.) Low and high noise, the accumulation of errors leads to the complete inability to locate
Therefore, it is still a great challenge to achieve accurate, reliable and real-time indoor positioning to meet various positioning needs.
