METHOD FOR DETERMINING OF STAND VOLUME GROWTH Russian patent published in 2006 - IPC A01G23/00 

FIELD: forest industry, in particular, remote solution of forestry tasks on the basis of program processing of forest images.

SUBSTANCE: method involves producing image of stocked wood in the form of dependences of function of image brightness I (x, y) from spatial coordinates; converting image brightness function into digital matrix of discrete readings by dimensions (mxn) of elements; performing program calculation of spatial spectrum of image of matrix under analysis and determining attachment point D_av=1/F_av of ogive of stand at plot under analysis; calculating stand volume by digital characteristics of matrix under analysis and mass tables; providing images of stocked woods comprising quadrates at temporary log during several years at one and the same growing periods of the year; evaluating area of crown canopy relief S_r of plot under analysis by program calculation of matrix, and calculating stand volume growth P_m from formulation: where F_av1, F_av2 is average frequency of spatial spectrum of image matrices produced at the beginning and end of temporary log; S_r1, S_r2 are areas of wood canopy relief of plot under analysis with the same time interval; D_av is average diameter of wood crown canopy; F_av is average frequency of spatial spectrum of image matrices.

EFFECT: increased precision, efficiency, reliability and statistic stability of result.
