Abstract

FIELD: forestry, in particular, operative evaluation of stand over extensive lands of unaccounted territories. SUBSTANCE: method involves remote production of large forest image; dividing it into mosaic portions; successively converting functions of portion image brightness into matrix of digital readings of brightness spatial dependence, with matrix scale being 512 x 512 elements; calculating characteristics of matrix electrical signal; mathematical waiting for root-mean-square deviation and spatial spectrum envelope; calculating plantation reserve of mentioned land on the basis of obtained data: M =x g x h, where M is stand reserve on land, cub m;is number of trees with crown diameter D D; Dis crown diameter of average-sized tree, calculated on the basis of spatial spectrum envelope D=; ais specific weight (amplitude) of respective harmonic of spatial spectrum; F is area of analyzed land equal to inner sizes of portion on copy multiplied by copy scale; P = D/ Dis completeness of plantation; Dis crown diameter of average-size tree calculated by statistical dependence of cover "roughness"; g,h is section area and height of average-size tree. Plantation reserve determining system has image 1 of forest, Panasonic-type input device 2, flexible magnetic disks 3, processor 4, printer 7, display 6. EFFECT: increased efficiency and precise data obtained by such method. 3 dwg

Использование: лесное хозяйство, в оперативной оценке запаса древостоя на обширных площадях неучтенных территорий. Сущность изобретения: способ включает операции дистанционного получения изображения лесного массива, разбиения его на мозаику участков, последовательного преобразования функции яркости изображения участков в матрицу цифровых отсчетов пространственной зависимости яркости размерностью 512 х 512 элементов, вычисление характеристик электрического сигнала матрицы, математического ожидания среднеквадратического отклонения, огибающей пространственного спектра, по которым рассчитывают запас насаждения анализируемого участка М. Способ реализуется на базе устройства, содержащего изображение лесного массива, которое посредством устройства ввода типа "Panasonic" последовательно по участкам преобразуется в матрицу пространственных отсчетов функции яркости и записывается в виде цифровых файлов на гибкие магнитные диски. Затем каждый элементарный участок вводится в процессор 4 IBM РС 386/387, на котором рассчитываются характеристики сигнала посредством программы цифровой обработки изображений "Видеолаб", записанной на ПЗУ 5. Результаты вычисления статистических характеристик сигнала распечатываются на принтере с возможностью визуализации расчетных функций на дисплее типа VGA.Usage: forestry, in the operational assessment of the stock of stands on vast areas of unaccounted territories. The inventive method includes the operation of remote image acquisition of the forest, dividing it into a mosaic of sections, sequentially converting the brightness function of the image of the sections into a matrix of digital samples of the spatial dependence of brightness with a dimension of 512 x 512 elements, calculating the characteristics of the electric signal of the matrix, the mathematical expectation of the standard deviation, the envelope of the spatial spectrum, which calculate the stock of the analyzed area M. The method of re It is implemented on the basis of a device containing an image of a forest, which, using a Panasonic-type input device, is sequentially converted into sections into a matrix of spatial samples of the brightness function and recorded in the form of digital files on flexible magnetic disks. Then, each elementary section is introduced into the processor 4 of IBM PC 386/387, on which the signal characteristics are calculated by means of the digital video processing program "Video Lab" recorded on ROM 5. The results of the calculation of the statistical characteristics of the signal are printed on a printer with the possibility of visualizing the calculated functions on a VGA-type display .
