Digital key calibration method and device, automatic calibration system and storage medium

Abstract

The embodiment of the invention discloses a digital key calibration method, which comprises the following steps of: monitoring attitude information of a digital key to be calibrated and azimuth information of the digital key relative to a vehicle machine in real time, guiding the digital key to reach each sampling point in a pre-planned static sampling point set according to a preset sampling sequence and the attitude information and the azimuth information of the digital key, and acquiring static RSSI calibration data of each sampling point; the attitude information comprises a roll angle, a pitch angle and a yaw angle; and monitoring attitude information and motion information of the digital key in real time, and regularly acquiring dynamic RSSI calibration data between the digital key and the vehicle machine according to a pre-planned dynamic sampling path and preset dynamic attitude motion conditions. Therefore, the inertial measurement unit is utilized to guide and position the sampling point, tedious manual measurement and positioning are avoided, automatic acquisition of calibration data can be realized, the calibration efficiency can be improved, and the calibration workload can be greatly reduced.
