DJI introduces the Phantom 4 Multispectral, aimed at precision agriculture and land management. According to the drone manufacturer, this will be its first drone with an integrated multispectral camera, built with the aim of helping to solve the current problems farmers face in a more efficient way.
DJI Phantom 4 Multispectral
DJI, the undisputed leader in civil drones and aerial imaging technology, is setting a new standard for easy-to-use agricultural drones with the Phantom 4 Multispectral, the company's first drone to already integrate a high-quality multispectral camera and combine it with RTK technology for more accurate data.
Phantom 4 Multispectral combines data from its six individual sensors to provide a representation of crop health, from individual plants to entire fields, as well as weeds, pests and a wide range of soil conditions. With the agricultural drone market expected to grow from $1.2bn in 2019 to $4.8bn by 2024, the P4 Multispectral provides farmers and agronomists with a new tool to improve crop yields, reduce costs and help environmental professionals easily monitor the vegetation on the land they manage.
"Phantom 4 Multispectral has the promise to transform the agriculture and land management industries by collecting accurate plant-level data without having to send staff into the field to conduct manual surveys," said Jan Gasparic, Director of Strategic Partnerships at DJI. "By combining multispectral imaging into one reliable, efficient and affordable tool, DJI is making this transformative technology more accessible to professionals around the world who are pioneering drone adoption in their industries."
Accurate multispectral imaging
P4 Multispectral features a gimbal-stabilised camera system, this system is comprised of an RGB camera and a multispectral camera array with five narrowband sensors - including red-edge and near-infrared - that are capable of capturing light visible and invisible to the human eye. This data provides trained professionals with unique insights into vegetation stress, soil composition, water salinity and pollution. Thanks to an additional integrated sunlight sensor, the phantom 4 multispectral maximises the accuracy and consistency of data collection during successive missions regardless of the time of day.
Thanks to the DJI Ground Station Pro flight planning application, pilots can switch between RGB and NDVI video camera views in real time to get an immediate view of the field situation. This model integrates an RTK positioning module and the TimeSync system which provides accurate, real-time positioning data for each image, optimising photogrammetric results and providing accurate centimetre-level measurements.
Industry workflow compatibility
P4 Multispectral is compatible with industry standard workflows, including flight scheduling, mapping and analysis software from DJI and other leading vendors. Using the DJI GS Pro application, users can create automated and repeatable missions, including flight planning, mission execution and flight data management. Collected data can be easily 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, Phantom 4 Multispectral users can enhance RTK positioning accuracy without the need for an internet connection by using DJI's high-precision D-RTK 2 mobile GNSS station, which is compatible with all major satellite navigation systems worldwide, or by using a third-party RTK network via an internet-connected iPad.
Built on the proven Phantom airframe, the Phantom 4 Multispectral takes advantage of DJI's powerful OcuSync transmission system to deliver a smooth flight experience, with less signal interference, improved video transmission and a maximum transmission range of 7km(FCC). Each of its 2-megapixel cameras features a global shutter for sharp in-flight images, up to 27 minutes per battery.
Live RGB and NDVI imaging
DJI P4 Multispectral allows you to switch between NDVI analysis and RGB imaging in real time, making it easy to make decisions as you fly.
RTK enabled and functioning properly:
Vertical: ± 0.1 m; Horizontal: ± 0.1 m
