The MAPIR T3-R50 Diffuse Reflectance Calibration Ground Target Package contains a series of 4 reflectance targets with known reflectance curves. UNLIKE drone “sunlight sensors” this target allows users to obtain accurately repeatable calibrated images through the seasons and in differing weather / lighting conditions. This target can be used for calibrating images with Mapir and any other brand of multispectral camera. A larger T3-R125 target is also available.
Before commencing a crop mapping survey cameras should capture an image of the entire target. This can then be used to help calibrate images captured in the image processing software.
We therefore highly recommend that you purchase the Mapir Camera Reflectance Calibration Target to complete your system.
