AI Technical Summary
Existing indoor positioning methods suffer from unstable wireless signals, which can easily lead to misjudgments of human location by electronic fences. Furthermore, they have low accuracy and low computational efficiency, making it difficult to achieve real-time and accurate indoor positioning.
A fence positioning method based on Bluetooth terminals is adopted. By scanning Bluetooth positioning beacons, Kalman filtering prediction and multi-dimensional calculation are used to determine the location information of the positioning terminal. The position of the terminal in the electronic fence area is determined by comparing the number of intersections. The area ratio is determined by combining the golden ratio to improve accuracy.
It improves the accuracy of indoor positioning, reduces system misjudgments, increases the utilization rate per unit area, reduces manual deployment costs, and improves work efficiency.
