Для автоматической классификации цилиндрических таблеток ядерного топлива их поворачивают вокруг собственной оси. На одной номинальной образующей боковой цилиндрической поверхности таблетки фокусируют плоский световой луч. Принимают возвращенный или отраженный свет, исходящий от удлиненной зоны, которая представляет собой зону, освещенную на поверхности таблетки без дефектов. Последовательно, точка за точкой, определяют интенсивность этого возвращенного света вдоль упомянутой выше зоны и делаю вывод о дефектах на основании изменений этой интенсивности. Для этого определяют точки каждой зоны, где упомянутая выше интенсивность возвращенного света заключена между двумя регулируемыми пороговыми значениями нормальности. Точки переходов запоминают и определяют границы каждого дефекта поверхности и его природу при помощи анализа сродства смежных точек.For automatic classification of cylindrical tablets of nuclear fuel, they are rotated around its own axis. A flat light beam is focused on one nominal generatrix of the lateral cylindrical surface of the tablet. Returned or reflected light coming from the elongated zone, which is the zone illuminated on the surface of the tablet without defects, is received. Consistently, point by point, the intensity of this returned light is determined along the aforementioned zone and I draw a conclusion about defects based on changes in this intensity. To do this, determine the points of each zone where the above-mentioned intensity of the returned light is enclosed between two adjustable threshold values of normality. Transition points memorize and determine the boundaries of each surface defect and its nature by analyzing the affinity of adjacent points.
