PHANTOM 4 MULTIESPECTRAL

 

Secure the health of your business

Secure the health of your business. The Phantom 4 Multispectral is a high-precision drone with an integrated multispectral imaging system built for agricultural missions, environmental monitoring and more.

Flight planning: Plan flights, run automated missions and manage through the DJI GS PRO app (DJI’s leading flight planning app for iOS).

Data collection: Collect multispectral imagery efficiently and over large areas.

Data analysis: Easily access and process air data by applying crop-specific parameters and metrics to obtain results related to crop health.

Operate on the database: Implement targeted phytosanitary treatments using the updated NDVI and RGB map.

IMMEDIATE INFORMATION ON PLANT HEALTH

The P4M through its multispectral sensor is able to provide information on crop health and vegetation conditions. DJI created this platform with the same performance standards for which the brand is known, it has a range of 27 minutes (maximum flight time) and has a range of up to 7 km, with the OcuSync system.

SEE BENEATH THE SURFACE

Agricultural image collection is now simpler and more efficient than ever, with a stabilised and integrated imaging system that allows access to information collected by 1 RGB camera and 5 multispectral cameras covering the Blue (B), Green (G), Red (R), RedEdge and Near Infrared (NIR) bands, all with 2MP, on a 3-axis stabilised gimbal.

MEANINGFUL DATA AT YOUR DISPOSAL

Having only aerial imagery is not enough for agricultural professionals. Switch between viewing normalised difference vegetation index (NDVI) analysis and real-time optical or RGB cameras. Immediately visualise where more attention is needed, make assertive and quick treatment decisions.

INTEGRATED SPECTRAL SUNLIGHT SENSOR

The P4M has an integrated spectral sunlight sensor on top to capture solar radiation, maximising the accuracy and consistency of the data captured.

D-RTK 2 MOBILE STATION AND NTRIP COMPATIBILITY

Increase RTK positioning accuracy without an internet connection by connecting the P4M to the D-RTK 2 high-accuracy GNSS mobile station. It is also possible with an internet connection to connect to NTRIP 2 (RTCM transport network via Internet Protocol), or even store satellite observation data to be used for post-processed kinematics (PPK).

FREQUENT QUESTIONS

PRODUCT

Product Frequently Asked Questions

What is the difference between the P4 Multispectral and the Phantom 4 RTK?

Both are RTK-capable drone platforms. The main difference is the camera. The P4 Multispectral includes an RGB camera and five 2 MP cameras each forming a multispectral array. The Phantom 4 RTK includes a single 20 MP RGB camera.

What propellers does the P4 Multispectral use?

It uses the 9455S noise reduction propellers. It is also compatible with the Phantom 4 series propellers, but flight performance will be affected.

What precautions should I take with the sunlight sensor on top of the drone?

Keep it away from hard or sharp objects and to avoid scratches.

GIMBAL CAMERAS

Frequently Asked Questions about Stabilizer Cameras

What are the capabilities of the multispectral camera array of the P4 Multispectral?

The multispectral imaging system of the P4 Multispectral detects light emissivity of different objects, which is captured by each of the cameras and analyzed to calculate vegetation index values. A common index used in the agriculture and forestry industry for plant health is NDVI. Meanwhile, the spectral sunlight sensor atop the drone compensates for the sunlight received throughout different times of day, improving the consistency of the data captured over the same field of vegetation. This increases the consistency of the information captured in the same field.

What are the Multispectral Imaging Bands covered by the multispectral cameras of the P4 Multispectral?

Blue (B): 450 nm ± 16 nm, green (G): 560 nm ± 16 nm, red (R): 650 nm ± 16 nm, red edge (RE): 730 nm ± 16 nm, near-infrared (NIR): 840 nm ± 26 nm. Each Sensor: Effective pixels 2.08 MP (2.12 MP in total)

What is the focal length for each camera on the P4 Multispectral?

All the camera lenses have a focal length of 5.74 mm, and the 35 mm equivalent focal length is 40 mm.

How are the cameras radiometrically calibrated?

Your images go through radiometric calibration when you process them through the vegetation index features in DJI GS Pro and DJI Terra.

Have the cameras on the P4 Multispectral gone through image position compensation?

Yes. The positions of the centers of the six cameras’ CMOS relative to the phase center of the onboard D-RTK antenna have been calibrated and are recorded in the EXIF data of each image.

Have the cameras lenses gone through distortion correction?

The original images do not have the distortion corrected but during the production process the distortion of the camera lens has been measured. The measurement result is saved in all images.

Has any vignetting correction been performed on the cameras?

The vignetting in the original images is not corrected, but the parameters for this correction are recorded in each of the images.

Is the TimeSync feature available for all six cameras?

Yes.

Do I need to use a high-speed SD card for the cameras?

Yes. Please refer to the manual when choosing an SD card.

How is the consistency of information collected by multispectral arrays of cameras and sunlight sensors from different drones ensured?

All P4 Multispectral aircraft have undergone a standardized camera and sensor calibration process that minimizes differences between drones.

Which values are recorded in the pixels of the images, the DN values or the reflectance values?

DN values.

Remote Controller

Frequently Asked Questions about Stabilizer Cameras

Which remote controls is the P4 Multispectral compatible with?

At this time, the P4 Multispectral is compatible only with the Remote Control SDK included with the aircraft.

Can I use the remote controls of other Phantom 4 series aircraft to operate the P4 Multispectral?

You will be able to link the aircraft to other Phantom 4 series remote controls, but you will not be able to operate the P4 Multispectral if you are not using a compatible remote control. You can use the P4 Multispectral remote control with the Phantom 4 RTK, but not the other way around.

TRANSMISSION

Frequently Asked Questions about Transmission

What is the video transmission range of the P4 Multispectral?

FCC / NCC: 7 km; SRRC / CE / MIC / KCC: 5 km (No obstructions or interference)

At what resolution can the P4 Multispectral transmit video?

720p

BATTERY

Frequently Asked Questions about Batteries

SOFTWARE

Frequently asked questions about the software

?

How can I upgrade the P4 Multispectral?

Using DJI Assistant 2 for Phantom. Follow these instructions www.dji.com/es/downloads/softwares/assistant-dji-2-for-phantom and those in the user’s manual.

What field survey and inspection applications are available for remote control?

The flight application included with the DJI GS Pro aircraft can be used to plan and execute flight missions.

What map does the P4 Multispectral application use?

DJI GS Pro uses Apple Maps.

Is there a limit to the number of benchmarks that can be used on each flight?

The number of landmarks that can be set in a mission is not limited, but actions can only be performed on 99 of them. When performing a mission with more than 99 waypoints, DJI GS Pro will automatically divide the mission into sections with a maximum of 99 waypoints each.

What are the altitude and speed limits?

Flying altitude: Maximum: 500 m Minimum: 1 m Flight speed: Maximum: 15 m/s Minimum: 1 m/s

Which flight mode should I use if I want to switch live between RGB and NDVI display?

You can switch between the two live in Manual mode. Recomendamos permanecer en la vista RGB y no cambiar el modo de visualización durante una misión de vuelo. JPEG images will be automatically saved in RGB or NDVI depending on the camera mode. Most third-party mapping software requires RGB imagery for aerial triangulation prior to compositing NDVI maps.

Which camera configuration is recommended?

For novice users, we recommend choosing the multispectral recording mode in Auto, Average Metering as the metering mode and unlocking AE.

Is the P4 Multispectral compatible with third-party software?

It will soon be compatible with software developed with the DJI Mobile SDK.

Which vegetation indices are supported by DJI Terra?

NDVI, GNDVI, NDRE, LCI, OSAVI. But it does not have a vegetation index calculation function.
