Assessing forage mass using smartphone imagery for cereal rye under grazing conditions in Nebraska

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Managing grazing efficiency requires reliable and practical tools to estimate forage mass. Traditional methods like clipping, though accurate, are time consuming and labor intensive. In this study, two imaging tools, Canopeo and the Crop Canopy Image Analyzer (CCIA), were evaluated for their efficacy in estimating the forage mass of cereal rye

Nondestructive testing with thermography

European Journal of Physics, 2013
Thermography is a nondestructive testing (NDT) technique based on the principle that two dissimilar materials, i.e., possessing different thermo-physical properties, would produce two distinctive thermal signatures that can be revealed by an infrared sensor, such as a thermal camera.
