| 成果简介 | NOVELTY - Invention relates to forestry and can be used in monitoring forests by aerospace equipment. Performing the tree canopy probing from the drone with a digital video camera and a spectrometer with measurements referenced by coordinates by means of the GLONASS global positioning system, calculation of structural characteristics of tree canopy by software image processing: average frequency Fav of spatial spectrum; crown diameter Dav=1/Fav of the model tree of the site; relief area Sr of tree canopy; tree stand completeness through ratio of geometrical area of plot Sgeometr to relief area Sr, measurement of characteristics of efficiency of conversion of light flux into biomass: colour of tree canopy according to spectrograms of spectral brightness coefficient (SBC) with calculation of normalized differential vegetation index NDVI; ground-based measurements by means of a fluorimeter of the coefficient (C) of absorption of the incident light flux by workpieces of shoots of crowns, determination of productivity [P%] from measurements on a time lag of several years (ΔT=T2-T1) through the ratio: . USE - Forestry. ADVANTAGE - Higher accuracy, efficiency and statistical stability of estimating margin gain. |
