Abstract

Изобретение направлено на сокращение времени работы алгоритма формирования панорамных изображений в целом и его реализацию в режиме реального времени. На изображениях кадров, полученных в результате гистологических, цитологических, эндоскопических и других исследований, выявляют множества характерных прямоугольных областей, определяя количество совместимых характерных прямоугольных областей, при этом изображение текущего кадра сравнивают с изображениями соседних опорных кадров, сравнение характерных прямоугольных областей осуществляют только в областях интереса текущего и опорных кадров, рассчитывают величину средней интенсивности пикселей изображения текущего кадра, определяют координаты вектора смещения текущего кадра относительно соседних опорных кадров, за координаты векторов смещения между текущим и опорными кадрами принимают средние координаты смещения между всеми совместимыми характерными прямоугольными областями на изображениях текущего и опорных кадров с их последующим уточнением путем наложения ограничений на величину среднеквадратичного отклонения координат векторов смещения совместимых характерных прямоугольных областей и на величину разницы между координатами векторов смещения совместимых характерных прямоугольных областей и их средних значений, изображение текущего кадра сдвигают относительно изображений соседних опорных кадров и добавляют к результирующему изображению, операцию сравнения характерных прямоугольных областей изображений осуществляют на процессоре видеокарты.The invention is aimed at reducing the time of the algorithm for generating panoramic images as a whole and its implementation in real time. The images of frames obtained as a result of histological, cytological, endoscopic and other studies reveal many characteristic rectangular areas, determining the number of compatible characteristic rectangular areas, while the image of the current frame is compared with the images of neighboring reference frames, the comparison of characteristic rectangular areas is carried out only in areas of interest current and reference frames, calculate the value of the average pixel intensity of the image of the current frame, determined by The coordinates of the displacement vector of the current frame relative to neighboring reference frames, the coordinates of the displacement vectors between the current and reference frames are taken as the average coordinates of the displacement between all compatible characteristic rectangular areas on the images of the current and reference frames with their subsequent refinement by imposing restrictions on the value of the displacement vector coordinates compatible characteristic rectangular areas and by the magnitude of the difference between the coordinates of the displacement vectors stimulated characteristic rectangular areas and their average values, the image of the current frame is shifted relative to the images of neighboring reference frames and added to the resulting image, the operation of comparing the characteristic rectangular image areas is performed on the video card processor.
