Abstract
[EN] An innovative methodology to generate vegetative vigor maps in vineyards (Vitis vinifera L.) has been developed
and pre-validated. The architecture proposed implements a Global Positioning System (GPS) receiver and a computer vision
unit comprising a monocular charge-coupled device (CCD) camera equipped with an 8-mm lens and a pass-band near-infrared
(NIR) filter. Both sensors are mounted on a medium-size conventional agricultural tractor. The synchronization of
perception (camera) and localization (GPS) sensors allowed the creation of globally-referenced regular grids, denominated
universal grids, whose cells were filled with the estimated vegetative vigor of the monitored vines. Vine vigor was quantified
as the relative percentage of vegetation automatically estimated by the onboard algorithm through the images captured with the
camera. Validation tests compared spatial differences in vine vigor with yield differentials along the rows. The positive
correlation between vigor and yield variations showed the potential of proximal sensing and the advantages of acquiring top
view images from conventional vehicles.Sáiz Rubio, V.; Rovira Más, F. (2013). Proximal sensing mapping method to generate field maps in vineyards. Agricultural Engineering International: CIGR Journal. 15(2):47-59. http://hdl.handle.net/10251/102750S475915
