Figure 27: FASTER selected cameras system geometry
Cameras are arranged in line, with the first camera tilted 15° on the right side and last
one tilted 15° on the left side. The first and third cameras are equipped with a Bayer filter
mosaic to obtain colored images while the central monochrome camera is equipped with a
nIR filter with 720 < λ < 850 nm. Cameras are Prosilica GE4000, equipped with a full
frame Kodak KAI-11002 CCD detector with 4008 x 2672 pixels and are described in the
following section, together with two selected lenses which are the Zeiss Distagon 28 mm
F/2.8 coupled with the colour cameras and the Zeiss Distagon 21 mm F/2.8 for the central
nIR camera.
The ground projections of the three cameras are shown in Figure 28; when used for
photogrammetric campaign such a system guarantees a maximum swath width,
normalized with respect to the flight height, of about 1.47 times the flight height (220 m
at 150 m of altitude). If also the nIR camera is used for remote sensing purposes (for
example to retrieve the NDVI index) the swath width decreases to 1.3 times the flight
height. The black dotted rectangle is the projection of the actual Canon EOS 450D APS-C
detector (Section 6.1.3) which uses a 28 mm lens; in this case the acquired area is 1.66
times smaller with respect to a full frame sensor.
