AI Technical Summary
Existing indoor positioning methods based on Wi-Fi signals lack universality and positioning accuracy in unknown environments, and require the prior deployment of Wi-Fi devices or the construction of fingerprint databases, which are costly and susceptible to signal attenuation and interference.
By acquiring inertial sensor data in real time to draw the movement trajectory, embedding the Wi-Fi signal RSSI value into the trajectory and synchronizing it over time, converting it into the distance between the device and the Wi-Fi device, and calculating the coordinates of the Wi-Fi device, positioning and navigation can be achieved without the need for pre-deployment of devices.
It improves the universality and accuracy of indoor positioning, reduces costs, overcomes the effects of signal attenuation and interference, and is suitable for unknown environments.
