A Local Fourier Transform approach for vine plot extraction from aerial images

Abstract

AbstractAn automatic tool for vineyard mapping and monitoring is expected by numbers of managers and winegrower cooperatives in winegrowing regions. A frequency analysis using the Fourier Transform on aerial images has been developed to meet this need. This results in vine plot detection, delineation and characterization with very precise estimation of inter-row width and row orientation. To foster large-scale applications, tests and validation have been carried out on standard very high spatial resolution remotely sensed data. On the study area, only 8% of vine plots have not been detected (corresponding to small plots with only 1.5% of the total vineyard surface) and more than 61% have been correctly detected (other mainly concerns partial detection).KeywordsSegmentationvery high spatial resolutionfrequency analysisvineyard managementcharacterization
