Abstract
The optimization of most pesticide and fertilizer applications
is based on overall grove conditions. In this paper,
we propose a measurement system to estimate the foliage surface
of a tree crop. The system is based on a ground laser scanner
that estimates the volume of the trees and then extrapolates their
leaf area using simple and fast algorithms to allow true real-time
operation. Tests with pear trees demonstrated that the relation
between the volume and the foliage can be interpreted as linear
with a coefficient of correlation (R) of 0.81, and the foliage surface
can be estimated from this volume with an average error less
than 6%.
