Spectral imaging has been growing rapidly and agriculture is an important market. However, the cost can be prohibitive for small farms (https://doi.org/10.1255/jsi.2022.a8). DJI have now introduced a multispectral version of their Mavic 3 drone, the Mavic 3 Multispectral, that should be affordable even for the smallest farm. The Mavic 3M has a four-lens multispectral camera in addition to the RGB camera. Each of the four multispectral cameras of can capture 5 million pixels and scan for the following wavelengths: green (560 nm ± 16 nm), red (650 nm ± 20 nm), red edge (730 nm ± 20 nm) and near infrared (860 nm ± 26 nm). These wavelengths provide for a number of potential agricultural and forestry applications including the NDVI vegetation index. A 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.
