How is the P4 Multispectral different from the Phantom 4 RTK? Both are RTK-enabled,
all-in-one drone platforms. The main difference is the camera. The P4 Multispectral comes
with an RGB camera and five cameras that make up a multispectral camera array, all at 2MP,
whereas the Phantom 4 RTK comes with a single RGB camera at 20 MP.
What propellers does the P4 Multispectral use? It uses the 9455S Low-Noise Propellers.
The Phantom 4 Series propellers are also compatible, but flight performance will be affected.
How do I take care of the Spectral Sunlight Sensor on top of the drone? Keep it away
from hard, sharp objects to prevent scratching.
What are the capabilities of the multispectral camera array of the P4 Multispectral?
The multispectral imaging system of the P4 Multispectral detects light emissivity of different
objects, which is captured by each of the cameras and analyzed to calculate vegetation index
values. A common index used in the agriculture and forestry industry for plant health is NDVI.
Meanwhile, the spectral sunlight sensor atop the drone compensates for the sunlight
received throughout different times of day, improving the consistency of the data captured
over the same field of vegetation.
What are the Multispectral Imaging Bands covered by the multispectral cameras of the
P4 Multispectral? Blue (B): 450 nm ± 16 nm, green (G): 560 nm ± 16 nm, red (R): 650 nm ±
16 nm, red edge (RE): 730 nm ± 16 nm, near-infrared (NIR): 840 nm ± 26 nm. Each Sensor:
Effective pixels 2.08 MP (2.12 MP in total)
What is the focal length for each camera on the P4 Multispectral? All the camera lenses
have a focal length of 5.74 mm, and the 35 mm equivalent focal length is 40 mm.
How are the cameras radiometrically calibrated? Your images go through radiometric
calibration when you process them through the vegetation index features in DJI GS Pro and
DJI Terra.
