Последовательные кадры видеопотока рассматриваются как квазистереопары, по которым вычисляется диспарантность центров головок ТВС. Реализован алгоритм обработки изображений, включающий подавление шумов, CLAHE-контрастирование, адаптивную бинаризацию, морфологическую фильтрацию, преобразование Хафа и субпиксельную локализацию. Проведено сравнение результатов измерения при различных базисах квазистереопары и выполнена оценка влияния субпиксельной локализации на итоговую точность. Показано, что наиболее устойчивые результаты достигаются при базисе 12 мм, при котором средняя ошибка определения разновысотности составляет около ±1,3 мм. Полученные результаты подтверждают принципиальную реализуемость метода параллакс-сдвига для задач телевизионного контроля объектов с регулярной структурой пространственного расположения.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents an experimental verification of the parallax-shift method for non-contact determination of height differences of fuel assembly heads from a series of television images obtained during arc-shaped movement of a single CCD camera. Consecutive video frames are considered as quasi-stereo pairs, from which the disparity of the centers of fuel assembly heads is calculated. An image processing algorithm has been implemented, including noise suppression, CLAHE contrast enhancement, adaptive binarization, morphological filtering, the Hough transform, and subpixel localization. The measurement results obtained with different quasi-stereo pair baselines are compared, and the influence of subpixel localization on the final accuracy is evaluated. It is shown that the most stable results are achieved with a baseline of 12 mm, at which the average error in determining height differences is approximately ±1.3 mm. The obtained results confirm the fundamental feasibility of the parallax-shift method for television-based inspection of objects with a regular spatial structure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>параллакс-сдвиг</kwd><kwd>квазистереопара</kwd><kwd>телевизионное изображение</kwd><kwd>видеопоток</kwd><kwd>субпиксельная локализация</kwd><kwd>преобразование Хафа</kwd><kwd>головки ТВС</kwd><kwd>бесконтактные измерения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>parallax shift</kwd><kwd>quasi-stereo pair</kwd><kwd>television image</kwd><kwd>video stream</kwd><kwd>subpixel localization</kwd><kwd>Hough transform</kwd><kwd>fuel assembly heads</kwd><kwd>non-contact measurements</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">Система бесконтактного определения разновысотности головок тепловыделяющих сборок в активной зоне реактора / В.
