Description
трещин преобразуют в пространственный спектр. По спектру определ ют направление максимально выраженной пространственной частоты, то есть пороговый сигнал.cracks are transformed into a spatial spectrum. The spectrum determines the direction of the maximum spatial frequency, i.e., the threshold signal.
Посредством считывающего устройства , например фототелеграфа, изображение пор и трещин преобразуетс в последовательность электрических опоных сигналов, причем направление развертки изображени определ етс направлением порогового сигнала пространственного спектра изображени , Размер чейки изображени , соответствующий импульсу, определ етс Минимальным размером исследуемых пор тили трещин . Сигналы развертки изображени последовательно ввод тс в вычислительное устройство, например в ЭВМ, где формируютс по соответствующей; программе сигналы, признаков объекта: общей, открытой и эффективной пористости , удельной поверхности открытых пор, проницаемость и т. п.The image of the pores and cracks is converted into a sequence of electrical signals by means of a reader, for example, photo-telegraph, and the direction of the image sweep is determined by the direction of the threshold signal of the spatial image spectrum. The size of the image cell corresponding to the pulse is determined by the Minimum size of the cracks under study. Image scan signals are sequentially input to a computing device, for example, in a computer, where they are generated according to the corresponding; the program signals object features: total, open and effective porosity, the specific surface of open pores, permeability, etc.
Введение новой последовательности операций, позволило существенно повысить точность определени признаков объектов.The introduction of a new sequence of operations made it possible to significantly improve the accuracy of determining the signs of objects.
