NON-DESTRUCTIVE METHOD AND DEVICE TO CALCULATE VIGOR AND VEGETATIVE EXPRESSION IN TREE-SHRUB VEGETATION AND APPLICATION THEREOF

摘要

The present invention refers to a non-destructive method for vigor and vegetative expression determination in tree- shrub vegetation, which is oriented along surfaces (e.g. grapevines and actinideae), regardless of their variety group. The method consists of acquiring an on-field digital image of the grapevine (1), which is subject to digital processing (2), giving way for the identification, localization and isolation of the reference mark (5), which will allow determining the area of a pixel, and the grapevine canes (6), in order to calculate the total area of the canes. Based on a pixel area in the total area of the canes, on the cane quantity and on the medium area per cane and medium weight per cane polynomial ratio (3), the vigor and vegetative expression (4) are thus obtained. The application field of this method may be, for example, the Wine-growing sector.
