We design a differential error learning strategy based on the kinematic motion model to train the sensor error compensation model. This strategy allows our method to learn IMU sensor errors, such as scale factors, axis misalignment, and biases, solely from displacement and orientation increments given by external tracking systems. Then, during the odometry computation, the trained model leverages the past inertial data to mitigate the sensor errors and thus reduces the integration errors to reflect the odometry state. The experiments conducted on two public visual\u2013inertial datasets show an average of 20% improvement in the position estimation accuracy of visual\u2013inertial odometry, which is comparable to existing learning-based methods with lower operational complexity.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" src=\"https:\/\/carelab.info\/wp-content\/uploads\/2023\/12\/tim-20230821-duet.jpeg\" alt=\"\" width=\"1692\" height=\"1016\" class=\"alignnone size-full wp-image-4326\" srcset=\"https:\/\/carelab.info\/wp-content\/uploads\/2023\/12\/tim-20230821-duet.jpeg 1692w, https:\/\/carelab.info\/wp-content\/uploads\/2023\/12\/tim-20230821-duet-300x180.jpeg 300w, https:\/\/carelab.info\/wp-content\/uploads\/2023\/12\/tim-20230821-duet-768x461.jpeg 768w, https:\/\/carelab.info\/wp-content\/uploads\/2023\/12\/tim-20230821-duet-1536x922.jpeg 1536w\" sizes=\"(max-width: 1692px) 100vw, 1692px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>Liu \u541b (M2) \u306e\u8ad6\u6587\u304c IEEE TIM (Transactions o <a class=\"more-link\" href=\"https:\/\/carelab.info\/ja\/2023\/08\/21\/mr-liu-m2s-paper-has-been-published-on-ieee-tim\/\">More &#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"pgc_meta":""},"categories":[1],"tags":[],"aioseo_notices":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts\/4325"}],"collection":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/comments?post=4325"}],"version-history":[{"count":1,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts\/4325\/revisions"}],"predecessor-version":[{"id":4327,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/posts\/4325\/revisions\/4327"}],"wp:attachment":[{"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/media?parent=4325"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/categories?post=4325"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/carelab.info\/ja\/wp-json\/wp\/v2\/tags?post=4325"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
