The DJI Phantom 4 Multispectral makes agriculture imagery collection simpler and more efficient than ever by combining one of DJI's most advanced drone models with a multispectral payload that includes 6 different sensors. All built into to a fully integrated 3 axis stabilized gimbal is an RGB camera and an array of blue, green, red, red edge, and near infrared bands all at 2 MP resolution with a global shutter. The array of sensors allows you to switch between RGB and Normalized Difference Vegetation Index (NDVI) in real time through the live feed on the controller to immediately bring the pilots attention to any abnormalities.
On top of the aircraft is an integrated spectral sunlight sensor which helps to maximize the accuracy and consistency of your data through different times of the day. When combined with post processed data, this information helps you obtain the most accurate NDVI results.
Get real-time, accurate positioning data on images captured by all six cameras with DJI’s TimeSync system, providing centimeter-level accurate measurements. The TimeSync system continually aligns the flight controller, RGB and NB cameras, and RTK module, fixing the positioning data to the center of the CMOS and ensuring each photo uses the most accurate metadata. All cameras go through a rigorous calibration process where radial and tangential lens distortions are measured. The distortion parameters gathered are saved into each image’s metadata, letting post-processing software adjust uniquely for every user.
Enhance the accuracy of RTK positioning without internet connection by connecting the P4 Multispectral to the D-RTK 2 High Precision GNSS Mobile Station and NTRIP (Network Transport of RTCM via Internet Protocol)2, or store the satellite observation data to be used for Post Processed Kinematics (PPK).
