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.

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.

Overview

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.

RTK Compatible

Centimeter-Level Precision

Real-time accurate data collection in the drone's imaging, down to the centimeter, 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 center 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.

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.

Centimeter-level Precision

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.
