Abstract: An image capture device may capture visible and infrared light, and image analysis may be used to generate a map of the Normalized Difference Vegetation Index (NDVI) of healthy vegetation. Because NDVI data focuses on red and near infrared (NIR) reflectance of plants, NDVI data may be generated using an aircraft-mounted camera with optical filtering to collect various wavelengths. To reduce the size, weight, complexity, and cost of the image analysis system, a multiband optical filter may be used to capture multiple passbands simultaneously.

Abstract: Multispectral cameras may be used for aerial imaging, such as in precision agriculture aerial imaging applications. In particular, multispectral camera mounted on an aerial vehicle may be used to determine vegetative indices of the plants being photographed. A multispectral imaging method may include optically filtering a plurality of images through a plurality of optical image filters within a swappable filter cartridge, receiving the filtered plurality of images at a plurality of image sensors within a multiple image sensor module, each of the plurality of image sensors corresponding to each of the plurality of optical image filters, and storing the received plurality of images at a memory within the multiple image sensor module.
