matching navigation is extensively utilized for localization and navigation of autonomous robots and vehicles owing to its advantages such as low cost, wide-area coverage, and no cumulative errors. However, due to the influence of magnetometer measurement noise, geomagnetic localization algorithms based on single-point particle filters may encounter mismatches during continuous operation, consequently limiting their long-range localization performance. To address this issue, this paper proposes a real-time sequential particle filter-based geomagnetic localization method. Firstly, this method mitigates the impact of noise during continuous operation while ensuring real-time performance by performing real-time sequential particle filtering. Then, it enhances the long-range positioning accuracy of the method by rectifying the trajectory shape of the odometry through odometry calibration parameters. Finally, by performing secondary matching on the preliminary matching results via the MAGCOM algorithm, the positioning error of the method is further minimized. Experimental results show that the proposed method has higher positioning accuracy compared to related algorithms, resulting in reductions of over 28.58%, 37.11%, and 0.77% in RMSE, max error, and error at the end, respectively.<\/jats:p>","DOI":"10.3390\/s24072120","type":"journal-article","created":{"date-parts":[[2024,3,26]],"date-time":"2024-03-26T11:05:33Z","timestamp":1711451133000},"page":"2120","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Geomagnetic\/Odometry Integrated Localization Method for Differential Robot Using Real-Time Sequential Particle Filter"],"prefix":"10.3390","volume":"24","author":[{"given":"Qinghua","family":"Luo","sequence":"first","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology at Weihai, Weihai 264209, China"},{"name":"Shandong Institute of Shipbuilding Technology, Ltd., Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mutong","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology at Weihai, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaozhen","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology at Weihai, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiquan","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology at Weihai, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenxu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology at Weihai, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boyuan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Harbin Institute of Technology at Weihai, Weihai 264209, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zhuang, Y.H., Yuan, C.Z., Lin, C.Y., Peconkova, V., and Lee, M.F.R.
