В основе предлагаемого решения лежит модификация алгоритма ORB-SLAM3, учитывающая особенности кинематики наземных роботов и использующая комплексирование данных визуальной и колесной одометрии, блочное уравнивание (bundle adjustment) для настройки параметров, комплексно характеризующих состояние визуального сенсора, а также алгоритм замыкания петли для корректировки карты. Результаты апробации на наборе данных OpenLoris показывают, что для ряда сценариев предлагаемое решение существенно превосходит по точности и робастности известный алгоритм ORB-SLAM3.</p></abstract><trans-abstract xml:lang="en"><p>The problem of improving the accuracy and robustness of simultaneous localization and mapping methods using numerical optimization with constraints is considered. The proposed solution is based on a modification of the ORB-SLAM3 algorithm, which takes into account the peculiarities of the kinematics of ground robots and uses the complexing of visual and wheel odometry data, bundle adjustment for setting parameters that comprehensively characterize the state of the visual sensor, as well as the loop closure algorithm to correct the map. Results of the approach approbation with an OpenLoris dataset demonstrate that for several scenarios the proposed solution is significantly superior in accuracy and robustness to the ORB-SLAM3 algorithm.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мобильные роботы</kwd><kwd>локализация</kwd><kwd>оптимизация</kwd><kwd>одометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mobile robots</kwd><kwd>localization</kwd><kwd>optimization</kwd><kwd>odometry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bailey T., Durrant-Whyte H.
