Abstract
Способ определения величины и направления перемещения контролируемого объекта путем представления его изображения на растровой сетке видеокамеры и определения совмещения видеоизображений из структуры растра, включающий двумерное измерение распределения интенсивности отраженного от объекта излучения в каждой строке эталонного и текущего растров и их последующую цифровую обработку, отличающийся тем, что путем выделения центральной части строк эталонного и текущего растров формируют сигналы укороченной длины, а цифровую обработку сигналов производят путем определения значения дискриминационной характеристики как разности корреляционных функций измеренных циклически сдвинутых укороченных строк эталонного растра и соответствующих строк текущего растра и последующей нормировки крутизны наклона дискриминационной характеристики на значение дискриминационной характеристики в крайних точках монотонной рабочей зоны, в зависимости от знака вычисленного значения дискриминационной характеристики, при этом величину и направление перемещения контролируемого объекта определяют усреднением оценок по всем строкам растра. The method of determining the magnitude and direction of movement of the controlled object by presenting its image on the raster grid of the camera and determining the combination of video images from the raster structure, including a two-dimensional measurement of the intensity distribution of the radiation reflected from the object in each line of the reference and current rasters and their subsequent digital processing, characterized in that by highlighting the central part of the lines of the reference and current rasters, shortened signals are generated, and digital processing Ignals are produced by determining the value of the discriminatory characteristic as the difference between the correlation functions of the cyclically shifted shortened lines of the reference raster and the corresponding lines of the current raster and then normalizing the slope of the discriminating characteristic to the value of the discriminating characteristic at the extreme points of the monotonous working area, depending on the sign of the calculated value of the discriminating characteristic, the magnitude and direction of movement of the controlled volume kta is determined by averaging the estimates over all rows of the raster.
