Effective aerial surveying needs to see the invisible. That's why Mavic 3 Multispectral has two forms of sight. It combines an RGB camera with a multispectral camera to scan and analyze crop growth with total clarity. Agricultural production management requires precision and data, and Mavic 3M delivers both.

Sunlight Sensor

The built-in sunlight sensor captures solar irradiance and records it in an image file, allowing for light compensation of image data during 2D reconstruction. This results in more accurate NDVI results, as well as improved accuracy and consistency of data acquired over time.

Accurate images that capture every pixel

Mavic 3M with RTK module for centimeter-level positioning. Flight control, the camera, and the RTK module sync in microseconds to accurately capture the location of each camera's imaging center. This enables Mavic 3M to do high-precision aerial surveying without using ground control points.

Omnidirectional obstacle sensing, terrain-follow aerial surveying

The aircraft features multiple wide-FOV vision sensors that accurately detect obstacles in all directions for omnidirectional obstacle avoidance. The terrain-follow aerial surveying can be easily performed in steep-slope landscapes.

Orchard mapping

Mavic 3M allows terrain-follow aerial surveying of orchards, even on sloped landscapes. Together with DJI Terra or DJI SmartFarm Platform [6] to reconstruct high-resolution orchard maps, automatically identify the number of trees, distinguish trees from other obstacles or objects, and generate three-dimensional operation routes for agricultural drones, making operations safer and more efficient.

Guide variable rate applications

For rice fertilization, cotton growth regulation, and potato foliar fertilizer spraying, the Mavic 3M is used to obtain multi-spectral images of crops. DJI Terra or the DJI SmartFarm Platform can then generate NDVI and other vegetation indices maps, capturing differences in crop potential and generating prescription maps that allow agricultural drones to execute variable-rate application. This ultimately allows users to reduce costs, increase yield, and protect the environment.

Intelligent field scouting

The Mavic 3M can carry out automatic field scouting. The field scout images can be uploaded to the DJI SmartFarm Platform [6] in real time through a 4G network. It can find abnormalities, such as emergence deficiencies, weed pressure, and crop lodging in a timely manner. It can also conduct intelligent analyses, such as cotton seedling identification and rice production testing, using AI identification for real-time sharing of crop growth information, guidance of agronomic activities, and easy management of 70 hectares of farmland by one person.

Environmental Monitoring and Natural Resources Survey

The Mavic 3M can also be used in environment and natural resource surveys, such as water enrichment monitoring, forest distribution surveys, urban green area surveys, and more.
