DJI P4 Multispectral drone for precision farming

P4 Multispectral combines data from six separate sensors to measure the health of crops, from individual plants to entire fields, as well as weeds, insects and a variety of soil conditions.

Precise multispectral imaging

P4 Multispectral features a gimbal-stabilised imaging system composed of one RGB camera and a multispectral camera array with five narrow band sensors – including red edge and near infrared – that are capable of capturing visible and invisible light. This data is to give professionals insights into vegetation stress, soil composition as well as water salinity and contamination.

According to DJI, an additional integrated spectral sunlight sensor maximises the accuracy and consistency of data collection during missions flown at different times of day.

Seamless integration into the DJI Ground Station Pro flight planning app allows pilots to switch between real-time views of the drone’s RGB video camera and Normalised Difference Vegetation Index (NDVI) output for immediate insights while in the field.

“P4 Multispectral has the promise to transform the agriculture and land management industries by collecting precise plant-level data without having to send personnel into the field for manual surveys,” said Jan Gasparic, Director of Strategic Partnerships at DJI. – Photos: DJI

Integrated RTK positioning module

An integrated RTK positioning module and TimeSync system support real-time, accurate positioning data for each image, optimising photogrammetric results and providing centimeter-level accurate measurements.

According to the manufacturer, P4 Multispectral is compatible with standard industry workflows including flight programming, mapping, and analytics software from DJI and other leading providers.

Import data

Using the DJI GS Pro application, users can create automated and repeatable missions including flight planning, mission execution, and flight data management. Data collected can be imported into DJI Terra or a suite of third-party software including Pix4D Mapper and DroneDeploy, for analysis and to generate additional vegetation index maps.

In addition, P4 Multispectral users can enhance the accuracy of RTK positioning without an internet connection by using DJI’s D-RTK 2 High-Precision GNSS Mobile Station, which supports all major global satellite navigation systems, or using a third-party network RTK via an iPad with an internet connection.

27 minutes of flight time per battery

Built on the Phantom airframe, P4 Multispectral leverages DJI’s OcuSync transmission system. DJI says this provides a smooth flight experience with less signal interference, enhanced video transmission, and a 7km maximum transmission range.

Each of its 2-megapixel cameras feature a global shutter for precise imaging during flight with a maximum 27 minutes of flight time per battery.
