DJI Phantom 4 Multispectral

A DJI Phantom 4 Multispectral can provide high-resolution NDVI and RGB imaging. With NDVI Imaging, spot areas for improvement using the iPad and the DJI Phantom 4 Multispectral will fly autonomously and take images in your field for your review. With that being said, you will be able to see a real-time NDVI map of the field when the drone is flying. Therefore, the next step will be uploading your photos to DJI Terra software.

RGB and NDVI Comparison

NDVI and RGB imaging is possible with the Phantom 4 Multispectral. As you can see in the image below, red indicates healthy vegetation. Yellow or green coloring indicates problems. You can discover this issue with the help of RGB imaging and NDVI imaging and address the issue in a timely manner. This issue may involve pests, irrigation systems or the destruction of the plant’s roots beneath the tractor’s tires.

What is Beneath the Surface

With a built-in stabilized imaging system, agriculture imagery collection has never been easier and more efficient than before. Access information collected from 1 RGB camera or a multispectral camera array with 5 cameras covering Blue, Green, Red, Red Edge, and Near-Infrared bands.

The light sensors offer you the capability to take the data at any time of the day and still be able to compare it with other NDVI maps that you have created before. The sensor light also adjusts the colors of the NDVI imaging if it is too sunny or cloudy.

Take photos taken by all six cameras with centimeter-level accuracy with DJI’s TimeSync system. It continuously aligns the flight controller, RGB and NB cameras, and the RTK module. This enables precise measurements and positional information to be provided to each photo. The images produced by a camera go through a rigorous calibration process, which measures both rotary and tangential lens distortions. The distortion parameters collected go into the image’s metadata, so that post-processing software can be adjusted individually for every user.

The P4 Multispectral GPS can be used with NTRIP for enhanced RTK positioning regardless of whether or not the mobile station and satellites are connected through the internet. Satellite observation data can also be used for Post Processed Kinematics.

Precision agriculture

Aside from general use, multispectral imagery can provide ag professionals with valuable information from across the electromagnetic spectrum. Knowing this information and the subsequently derived Vegetation Index data will allow them to make timely and informed decisions resulting in reducing costs and saving resources maximizing yields.

Environmental monitoring and inspection

Plant inspections and maintenance can be handled more efficiently and economically when using the P4 Multispectral – harness its actionable multispectral insights to monitor forest health, measure biomass, map shorelines, and manage riparian vegetation while protecting habitats and ecosystems.
