Wireless charging positioning and calibration method and system

The invention discloses a wireless charging positioning and calibration method and system. The method comprises the following steps that ground equipment obtains an equal RSSI value function curve based on a preset rotation angle according to different vehicle type ground clearance heights and different temperatures at a plurality of actual measurement points; a background system stores the equalRSSI value function curve and the ground equipment identification information corresponding to the equal RSSI value function curve; during carrying out wireless charging positioning, vehicle-mounted equipment reports the acquired equal RSSI value function curve request message to the background system; the background system acquires the corresponding equal RSSI value function curve and returns thecorresponding equal RSSI value function curve to the vehicle-mounted equipment according to the equal RSSI value function curve request message reported by the vehicle-mounted equipment; and the vehicle-mounted equipment acqu
