DJI Phantom 4 P4 Multispectral

The P4 Multispectral (Phantom 4 Multispectral) is a fully integrated multispectral imaging drone designed for precision agriculture and environmental management. Combining data from six separate sensors to measure crop health, from individual plants to entire fields, weeds, insects and various soil conditions, the P4 Multispectral sets a new standard for easy agricultural drone applications.

Description

The DJI P4 Multispectral, from the DJI Phantom 4 range, is a high-precision drone with a perfectly integrated multispectral imaging system, designed for agricultural missions, environmental monitoring and many other applications.

Get immediate insight into the health of your plants

The P4 Multispectral consolidates the data collection process to provide you with insight into plant health and assist you in the management of your crops.

This new platform meets the same performance standards that DJI is famous for, including a maximum flight time of 27 minutes and a transmission range of up to 5 km with the OcuSync V2.0 system.

Main characteristics 

Accurate multispectral imaging

The integrated stabilized imaging system collects complete sets of data immediately. Access the information collected by 1 RGB camera and a multispectral camera array with 5 cameras covering the blue, green, red, red edge and near infrared bands – all at 2 MP with global shutter, on a stabilized 3-axis gimbal.

Compatible Software

Use DJI Ground Station Pro to create automated and repeatable missions, including flight planning, mission execution, and flight data management. The collected data can be easily imported into DJI Terra and a third party software suite.

Centimeter precision

Obtain precise, real-time positioning data for images taken by all six cameras with DJI’s TimeSync system, which provides centimeter-accurate measurements. The TimeSync system constantly synchronizes the flight controller, RGB and NB cameras and RTK module, fixing the positioning data in the center of the CMOS and thus ensuring that each photo uses the most accurate metadata and defines the positioning data accordingly from the center of the CMOS sensor. All cameras go through a rigorous calibration process in which radial and tangential lens distortions are measured. The distortion parameters collected are saved in the metadata of each image, which allows the post-processing software to function uniquely for each user.

Compatibility with D-RTK 2 mobile station and NTRIP

Improve the accuracy of RTK positioning without an Internet connection by connecting the P4 Multispectral to the D-RTK 2 high-precision GNSS mobile station and NTRIP protocol (RTCM data network transport via Internet protocol) 2, or store satellite observation data to be used for post-processed kinematics (PPK).

Built-in Spectral Pyranometer for Accurate Results

A built-in spectral pyranometer on top of the drone measures solar radiation, which maximizes the accuracy and consistency of data collection at different times of the day. Combined with post-processed data, this information provides the highest precision NDVI results.

 View RGB and NDVI streams

Aerial imagery is not enough for agricultural professionals who want additional information. Switch between a preliminary render of the Normalized Difference Vegetation Index (NDVI) and the live RGB feed so you can immediately see where attention is needed so as to quickly make targeted treatment decisions.
