The use of a laser scanner for measuring crop properties in three different crops in Central Greece

Abstract

A sensing platform using a laser scanner was developed for data collection for the crop in the field. Crop height and biomass from three crops (sunflower, soybeans and winter wheat) were estimated. The sensing platform was mounted on a tractor, ran along the crop and measured the crop height and biomass. The relevant crop parameters were measured manually and compared to the values estimated based on instrument measurements. High correlation coefficients were generally observed and varied according to the growth stage of the crop. The correlation was both high for estimating crop height (r2=0.94 to r2=0.90) and for biomass mass (r2=0.879 to r 2=0.83).
