Задача реализована в численном эксперименте с использованием модели стереоизображения круга Снеллиуса (подводного изображения небосвода) для заданного рельефа морской поверхности. Проанализировано влияние параметров фотокамеры, геометрии наблюдения, освещения и волнения на качество построения карт диспарантности (смещения), необходимых для восстановления дальностей до визируемых элементов морской поверхности. Сформулированы рекомендации по методике проведения натурного эксперимента с целью апробации предложенного метода.</p></abstract><trans-abstract xml:lang="en"><p>On a qualitative level, the possibilities of using optical stereo images of the sea surface, registered from under the water, are considered in relation to the problem of remote diagnostics of waves. The task is implemented in a numerical experiment using a stereo image model of the Snell’s window (underwater image of the sky) for a given relief of the sea surface. The influence of the camera parameters, observation geometry, illumination and excitement on the quality of constructing disparity maps, necessary to restore the distances to the sighted elements of the sea surface, is analyzed. Recommendations on the methodology of a full-scale experiment in order to test the proposed method are formulated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дистанционное зондирование</kwd><kwd>подводное видение</kwd><kwd>стереовидение</kwd><kwd>диспарантность</kwd><kwd>изображение морской поверхности</kwd><kwd>круг Снеллиуса</kwd><kwd>ветровое волнение</kwd><kwd>уклоны поверхности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>remote sensing</kwd><kwd>underwater imagery</kwd><kwd>stereo imagery</kwd><kwd>disparity</kwd><kwd>Snell’s window</kwd><kwd>sea roughness</kwd><kwd>wind waves</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19-35-60034</funding-statement><funding-statement xml:lang="en">The reported study was funded by RFBR, project number 19-35-60034</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cox C., Munk W.
