Идея автономного позиционирования БПЛА заключалась в последовательном сравнении соседних пар кадров видеопотока для отслеживания перемещений носителя видеокамеры в промежутке времени между упомянутыми кадрами. Цель исследования — по результатам сравнительного анализа алгоритмов выделить те, которые наилучшим образом позволяют отслеживать координаты носителя. Реальные полетные данные, используемые для построения контрольной траектории, получены с помощью макетного образца летательного аппарата самолетного типа, оснащенного бортовой инерциальной навигационной системой, имеющей набор микроэлектромеханических сенсоров, и визуальным одометром с надир-ориентированной видеокамерой. Сопоставление реальных полетных данных и результатов работы алгоритмов производилось по нескольким показателям качества: минимуму среднеквадратической ошибки позиционирования, максимальному отклонению от контрольной траектории и среднему времени, необходимому для обработки пары соседних кадров. Результаты сравнения алгоритмов сведены в таблицу, также для наглядного сравнения приведены графики контрольной траектории и оценок, полученные с помощью данных алгоритмов. По совокупности показателей качества позиционирования для реализации рекомендованы нейросетевые алгоритмы d2net, darkfeat и XFeat(dense).</p></abstract><trans-abstract xml:lang="en"><p>Known algorithms for detecting and matching singular image points are presented when solving the problem of autonomous positioning of an unmanned aerial vehicle (UAV) equipped with a video camera in the absence of a signal from the global satellite navigation system. The idea of autonomous UAV positioning was to sequentially compare adjacent pairs of video stream frames to track the movements of the video camera carrier in the time interval between the mentioned frames. The purpose of the study is to identify those that best allow tracking the coordinates of the carrier based on the results of a comparative analysis of algorithms. The real flight data used to construct the control trajectory was obtained using a mock-up model of an aircraft-type aircraft equipped with an on-board inertial navigation system with a set of microelectromechanical sensors and a visual odometer with a nadir-oriented video camera. The comparison of real flight data and the results of the algorithms was carried out according to several quality indicators: the minimum standard deviation of the positioning error, the maximum deviation from the control trajectory, and the average time required to process a pair of adjacent frames. The results of comparing the algorithms are summarized in a table, and graphs of the control trajectory and estimates obtained using these algorithms are also provided for visual comparison. According to the set of positioning quality indicators, the neural network algorithms d2net, darkfeat and XFeat(dense) are recommended for implementation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>визуально-инерциальный одометр</kwd><kwd>автономная навигация</kwd><kwd>матрица гомографии</kwd><kwd>инерциальная навигационная система</kwd><kwd>детектор особых точек</kwd><kwd>беспилотный летательный аппарат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>visual-inertial odometer</kwd><kwd>autonomous navigation</kwd><kwd>homography matrix</kwd><kwd>inertial navigation system</kwd><kwd>singular point detector</kwd><kwd>unmanned aerial vehicle</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">Мирошниченко А.
