Abstract

The present invention provides a wireless signal compensation method, system, computer equipment and storage medium, the method comprising: obtaining the position information of the wireless beacon scanned by the positioning terminal at the current positioning position; obtaining the positioning result of the positioning terminal at the previous positioning position; According to the positioning result of the previous positioning position and the position information of the wireless beacon, determine the azimuth angle of the connection between the positioning result of the previous positioning position and the wireless beacon; according to the obtained position information of the wireless beacon, determine the target that needs to update the signal strength Wireless beacon; obtain the signal strength of the target wireless beacon scanned by the positioning terminal at the current positioning position and the pointing azimuth of the positioning terminal at the current positioning position; update the signal strength of the target wireless beacon according to the connection azimuth and pointing azimuth; According to the updated signal strength of the target wireless beacon, the positioning result of the positioning terminal at the current positioning position is determined. To achieve the purpose of solving the mutual interference of wireless signals in indoor positioning.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to a wireless signal compensation method, system, computer equipment and storage medium. Background technique [0002] The current mainstream indoor positioning technology mainly relies on wireless beacons deployed in the indoor environment, such as Bluetooth and WIFI routers. Generally, the formula of the transmitted signal strength and distance propagation loss of wireless beacons is used to calculate the distance between each wireless beacon and the positioning terminal. Distance, and then the coordinates of the positioning terminal are obtained through the triangulation positioning formula or the distance weight method. This positioning method greatly depends on the transmission strength of the wireless beacon, and has higher requirements for signal stability. [0003] Due to the existence of multipath effects, the wireless signals of wireless beacons will interfere...
