| Abstract: | The calibration values of geomagnetic parking detectors change over time. This paper studies the characteristics of the variation of calibration values of the geomagnetic parking detectors, and proposes an online calibration method based on statistical analysis to achieve online automatic calibration of geomagnetic parking detectors and to improve the accuracy of the parking status judgement. In the online calibration method, the range of variation of the calibration value is analyzed on the basis of statistical method, the variation of the calibration values is tracked, and calibration values are revised periodically. A practical application verifies the feasibility of the online calibration method. |
