Abstrakt
Precision spraying is one of the techniques for the reduction of pesticides use and it
can help achieve the new European Green Deal standards. The aim of such technique is to apply
the right amount of pesticides according to the target characteristics. The precision spraying
implementation requires target volume assessment, which can be carried out by LiDAR sensors.
Such technique requires complex and time-consuming procedures of canopy characteristics
computing through post-processing points cloud reconstruction. The present work aimed to
develop and test an algorithm through the use of a tractor-coupled with terrestrial LiDAR and
GNSS technology in order to simplify the process. With the aim to evaluate the algorithm the
LiDAR-based volume was correlated with two manual measurements of canopy volume (Tree
Row Volume and Point Net Cloud). The results showed good correlations between manual and
LiDAR measures both for total canopy volumes (R
2 = 0.67 and 0.56) and for partial canopy
volume (R
2 = 0.74). In conclusion, although the LiDAR-based algorithm works in automatic
mode, the canopy volumes approximation seems acceptable to estimate the canopy volumes, with
the advantages of a swifter procedure and less laborious post-processing computations.
