摘要
Abstract
In industrial applications of geomagnetic positioning technology,it is necessary to pre-acquire the magnetic induction intensity within the positioning area and establish a high-precision geomagnetic map.However,the magnetic induction intensity in the positioning zone may fluctuate due to environmen-tal changes at the operational site,which can degrade geomagnetic positioning accuracy.While regular measurement and collection of geomagnetic maps can mitigate this issue,such methods are constrained by poor real-time performance and high costs.To address the challenge of real-time geomagnetic map updates during practical applications,a road geomagnetic map updating method proposed for geomagnetic positioning.By analyzing the similarity between real-time maps and baseline maps,online real-time updates to the geomagnetic map is performed the method by using data acquired during real-time position-ing when significant discrepancies between the two maps arise due to environmental changes.The position-ing reliability validated by field data from a power plant is significantly enhanced by this updated method,a simple yet effective technical solution is achieved for the maintenance and updating of geomagnetic maps impacted by environmental changes during the deployment of geomagnetic positioning technology.关键词
