Agrowing revolutionizes precision agriculture by using the highend
NDVI maps, which are produced by Agrowing’s sensors, as
the pedestal for its innovative patent pending Remote&Close
NDVI and similar multispectral metrics and maps have limited
value. They provide assessments and guesstimations, which call
Agrowing’s Remote&Close Sensing provides the grower with
accurate actionable data, which minimizes and even eliminates
the need for such verification.
The unique design of Agrowing’s sensors and our imagery acquisition
method, result in the ability to analyze extremely high-resolution
multispectral data, which is collected from outlying and suspicious
areas of interest, as an additional step to our high-end traditional
NDVI. Such areas are in many cases inaccessible to the agronomists.
Agrowing’s vision and technologies enable accurate in-the-field
automatic machine-vision and machine-learning identification of
agricultural hazards like pests, diseases and irregularities like stress
and nutrient deficiencies.
Most airborne multispectral imaging systems employ
multiple CCD cameras, each of which is equipped with a
different bandpass filter. This approach has the advantage
that each camera
can be individually adjusted for optimum focus and
aperture settings, but has the disadvantage that the
images from all the bands have to be properly aligned.
With multiple optical systems, it is very difficult to
achieve this alignment optically or mechanically, so a
software-based registration procedure is commonly
used to align the band images.” Chenghai Yang USDAARS

Agrowing’s patent pending technology enables perfect
alignment at all times and eliminates the need for
frequent hardware calibration.
Multi cameras can hardly be synchronized for
perfect matching of the acquired imagery using
fast moving drones. A gap of 20ms could result in
20cm distance for a drone flying at 10m per second.
Comparing two point of views that remote from
each other is detrimental to reliable remote sensing.
Agrowing’s patent pending technology enables using
100% synchronized imagery acquisition by using a
single camera with a single sensor and a single shutter.
Most of the multi spectral cameras use inferior optics
of short focal length (wide angle) low resolution and
high distortion. It is not uncommon to find that some
of the “leading” multi spectral cameras are of 1 or 1.3
Mega Pixel and that the distortion of the lens exceeds
15%… As a result using such cameras means that a lot
of pre-processing is required in order to start analyzing
the data, a process in which pixels are manipulated
and changed. This means that even the declared low
resolution is not the actual resolution captured by those
Agrowing’s lenses are of very low distortion and high
resolution. NDVI/Red-Edge and 3D modeling can be
acquired in a single flight due to the low distortion
of the lenses.
