RedEdge-MX - even better now

RedEdge-MX is a multispectral camera made by Micasense company (USA). That model known by excellent value for money. New RedEdge-MX doesn't have any problems with overheat and RGB images processing.

Camera's kit is included new upgraded Downwelling Light Sensor (DLS2).

Camera's shots

Agisoft Metashape has some automatic functions for RedEdge-MX data processing.

For example, Metashape can detect QR-bars, that used for calibration. Information from downwelling light sensor automaticlly copied from photos metadata.

Laptop for data processing

Application with UAVs

RedEdge-MX camera is capable with Geoscan and other UAVs. We recommended use that with Geoscan 201 series with special CAN bus for many types of payloads.

Captures five narrow spectral bands. Some of them is not available for other RGB and IR cameras

You can change pixel radiance digital number (DN) to coefficients of spectral radiance by using data about sensors and sunlight calibration

Survey data can de used for to make composite raster images, pseudo color combinations with red edge channel to separate cultivated plants and weeds

Wavelengths 10-40 nm

Way to calculate vegetation indices
