DropVision®-AG & Forestry
What is DropVision®-AG?
DropVision®-AG is designed for the user
who applies liquid products that produce larger droplets
associated with agriculture, forestry and larvaciding
applications. The droplet range would be defined by The
American Society of Agricultural and Biological Engineers
as ASABE Very Fine through ASABE Course to Very
Coarse. DropVision®-AG provides many advantages
unavailable from other technologies. Specifically,
DropVision®-AG performs swath characterizations, deposition
volumes, droplet densities an
d detailed droplet spectrum
analysis. A very recent addition to DropVision®-AG is the
ability to monitor off-site drift using a geographical
information system (GIS) and TracerVision.

How does DropVision-AG® Work?
DropVision®-AG, through advance software
engineered processes, scans water or kromekote cards from a field portable scanner, powered by the USB port
of a mobile computer. DropVision®-AG also provides the feature
of analyzing previously
scanned images, as those files can be loaded directly into the
software. Once the images are loaded, each car
d can be
analyzed individually or automatically processed. This
feature is only offered by DropVision®-AG and typically
processes forty cards in twenty seconds. The image above
demonstrates the advanced software features of qualifying a
droplet, by circling the droplet signature with a green polygon.
The system operator can click on any individual droplet and
exclude it from the results. Another feature is the
ability to "crop" an image from each side, top or bottom of the
image.
The main software control page displayed
to the right shows each card has been processed as indicated by
the green icon in the left column and is accompanied with
detailed information that includes Sample Number, Distance from
center card, Number of Droplets counted, Total Volume, VMD or
DV0.5', Droplet Density/cm2 and Volume/Acre. The user can
select between metric or US standard.
Completing the analysis of each card,
the user can choose to Analyze Set, resulting in the creation of
the DV0.1' DV0.5' DV0.9 and the NMD graphs, the Density graphs
of Drops/cm2 and Application Rate Graph. Additionally the
COV (coefficient of variation) graph is produced accompanied
with a dynamic or live analysis of the effective swath, allowing
the user the feature of changing the lane separation and adding
up to ten passes. This provides the user the ability to
see the deposition results when applying multiple passes in an
operational setting.
More about DropVision®-AG:
DropVision®-AG, through engineered processes, incorporates proprietary software that eliminates all background particles, only recognizing those droplets that contain a unique fluorescence tracer signature using TracerVisionTM. DropVision®-AG electronically captures images contained on the slide, analyzing each droplet while eliminating any background objects or non-qualified droplets. This is accomplished by utilizing advanced proprietary image analysis algorithms only found in DropVision® technologies.
What are the primary components of DropVision®-AG:
DropVision®-AG consists of a specialized mobile scanner with a built-in dynamic link libraries; DropVision®-AG Advanced Droplet Image Analysis software; and the DropVision®-AG Graphing & Reporting software.
Does DropVision®-AG analyze and report
the requirements of the new EPA labels?
Yes. DropVision®-AG provides the user with the new and current label language requirement standards. DropVision®-AG specifically incorporates DV.1, DV.5, DV.9, droplet densities per millimeter squared and relative span.
Does DropVision®-AG analyze more than one image?
Yes. DropVision®-AG can analyze one card image or an unlimited number of images from multiple locations or sources. This makes DropVision®-AG very unique and capable of analyzing images for a single aircraft calibration or a complex network of droplet collection stations in a wide area ground or aerial application.
How accurate is DropVision®-AG?
Statistical analysis of DropVision®-AG compared to alternative methods, demonstrated comparable results. It should be noted that DropVision®-AG through the proprietary image analysis algorithms measures droplet sizes as small as one pixel (.5 micron). This advanced and unmatched measuring technique produces a more precise and accurate measurement of droplet sizes as compared to conventional methods.
