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.
