DJI P4 Multispectral Agricultural Drone
From agriculture to environmental research, the P4 Multispectral Agricultural Drone from DJI can be an invaluable tool in monitoring, understanding, and treating issues related to crop and vegetation health with information that’s invisible to the human eye. Utilizing a gimbal with a 6-camera array, this drone can see below the surface. One camera is an RGB camera dedicated to visible light and capturing standard photos, while the other five capture various other wavelengths.
The other five cameras capture 2MP images in red edge, near-infrared, green, red, and blue wavelengths. The global shutter and 3-axis stabilized gimbal help ensure the resulting images are clear, even while flying at higher speeds. While flying, you can switch between the two feeds to maximize data collection and focus on areas that need the most attention.
An integrated spectral sunlight sensor on the top of the P4 Multispectral quadcopter works in conjunction with the gimbal camera to achieve the most accurate NDVI results possible. The sensor captures solar irradiance to help increase accuracy and maintain consistency in processed data through different times of the day.
Real-time accurate data collection in the drone’s imaging, down to the centimetre, thanks to DJI’s TimeSync system. TimeSync has the P4 continually aligning the flight controller, gimbal camera, and RTK module; fixing the positioning to the centre of the CMOS. This helps give your photos extremely accurate metadata for post-processing software to utilize.
In addition, the gimbal cameras have already gone through a calibration process where radial and tangential lens distortions are measured. The distortion information is saved to each image’s metadata, allowing optional post-processing software to adjust for more accurate results.

Gain Immediate Insights into Plant Health
The P4 Multispectral consolidates the process of capturing data that gives insight into crop health and vegetation management. DJI has created this platform with the same powerful performance standards that DJI is known for, including 27 minutes max flight time and up to 7 km1 transmission range with the OcuSync system.
See Beneath the Surface
Agriculture imagery collection is now simpler and more efficient than ever before with a built-in stabilized imaging system that collects comprehensive data sets right out of the box. Access information collected by 1 RGB camera and a multispectral camera array with 5 cameras covering Blue, Green, Red, Red Edge, and Near Infrared bands – all at 2 MP with global shutter, on a 3-axis stabilized gimbal.
Integrated Spectral Sunlight Sensor for Accurate Results
An integrated spectral sunlight sensor on top of the drone captures solar irradiance, which maximizes accuracy and consistency of data collection through different times of day. When combined with post-processed data, this information helps to obtain the most accurate NDVI results.
Meaningful Data at Your Disposal
View Both RGB and NDVI Feeds
Simply having aerial imagery is not enough for ag professionals who want to know more. Switch between a preliminary Normalized Difference Vegetation Index (NDVI) analysis and the live RGB feed to immediately visualize where attention is needed, so targeted treatment decisions can be made quickly.
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.
D-RTK 2 Mobile Station and NTRIP Compatibility
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).
The Beginning of Intelligent Agriculture Missions
Plan flights, execute automated missions, and manage flight data using GS PRO – DJI’s leading flight planning iOS app.
Collect multispectral images efficiently across a large area using the P4 Multispectral and gain an overview of problem areas.
Easily access and process aerial data by applying plant-specific metrics and parameters to acquire the desired results on plant health.
Throughout all growing seasons, multispectral imagery can be helpful to ag professionals by providing information invisible to the human eye across the electromagnetic spectrum. Having access to this data and the subsequently obtained Vegetation Index data such as NDRE and NDVI, farmers can make timely, informed decisions on crop treatment, lowering costs, saving resources, and maximizing yields.
Environmental monitoring and inspection
Routine inspections and maintenance involving plants can be made smarter and more efficient when using the P4 Multispectral – leverage its actionable multispectral insights to monitor forest health, measure biomass, map shorelines, or manage riparian vegetation while protecting habitats or ecosystems, and much more.
