Given the demand for the acquisition of agricultural equipment roll angles, a roll angle monitoring model based on Kalman filtering and multi-source information fusion was established by using the MTi-300 AHRS inertial sensor (INS) and XW-GI 5630 BeiDou Navigation Satellite System (BDS), which were installed on agricultural equipment. Data of the INS and BDS were fused by MATLAB; then, Kalman filter was used to optimize the data, and the state equation and measurement equation of the integrated system were established. Then, an integrated monitoring terminal man\u2013machine interactive interface was designed on MATLAB GUI, and a roll angle monitoring system based on the INS and BDS was designed and applied into field experiments. The mean absolute error of the integrated monitoring system based on multi-source information fusion during field experiments was 0.72\u00b0, which was smaller compared with the mean absolute errors of roll angle monitored by the INS and BDS independently (0.78\u00b0 and 0.75\u00b0, respectively). Thus, the roll angle integrated model improves monitoring precision and underlies future research on navigation and independent operation of agricultural equipment.<\/jats:p>","DOI":"10.3390\/s20072082","type":"journal-article","created":{"date-parts":[[2020,4,8]],"date-time":"2020-04-08T05:59:47Z","timestamp":1586325587000},"page":"2082","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["An Acquisition Method of Agricultural Equipment Roll Angle Based on Multi-Source Information Fusion"],"prefix":"10.3390","volume":"20","author":[{"given":"Yang","family":"Li","sequence":"first","affiliation":[{"name":"Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun 130022, China"},{"name":"College of Biological and Agricultural Engineering, Jilin University, Changchun 130022, China"},{"name":"Graduate School of Agriculture, Kyoto University, Kyoto 6068502, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Honglei","family":"Jia","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun 130022, China"},{"name":"College of Biological and Agricultural Engineering, Jilin University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4644-6273","authenticated-orcid":false,"given":"Jiangtao","family":"Qi","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun 130022, China"},{"name":"College of Biological and Agricultural Engineering, Jilin University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huibin","family":"Sun","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun 130022, China"},{"name":"College of Biological and Agricultural Engineering, Jilin University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinliang","family":"Tian","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun 130022, China"},{"name":"College of Biological and Agricultural Engineering, Jilin University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huili","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Bionic Engineering, Ministry of Education, Jilin University, Changchun 130022, China"},{"name":"College of Biological and Agricultural Engineering, Jilin University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuhui","family":"Fan","sequence":"additional","affiliation":[{"name":"Agricultural Machinery Research Institute of Jilin Province, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1016\/j.compag.2019.01.010","article-title":"Roll angle estimation using low cost MEMS sensors for paddy field machine","volume":"158","author":"Hu","year":"2019","journal-title":"Comput.
