Outdoor Applications of Hyperspectral Imaging Technology for Monitoring Agricultural Crops: A Review

초록

applications, the use of analytical hyperspectral imaging techniques has been expanded to include monitoring of agricultural cropsand commodities due to the broad range and highly specific and sensitive spectral information that can be acquired. Combininghyperspectral imaging with remote sensing expands the range of targets that can be analyzed. Results: Hyperspectral imagingtechnology can rapidly provide data suitable for monitoring a wide range of plant conditions such as plant stress, nitrogen status,infections, maturity index, and weed discrimination very rapidly, and its use in remote sensing allows for fast spatial coverage. Conclusions: This paper reviews current research on and potential applications of hyperspectral imaging and remote sensing foroutdoor field monitoring of agricultural crops. The instrumentation and the fundamental concepts and approaches ofhyperspectral imaging and remote sensing for agriculture are presented, along with more recent developments in agriculturalmonitoring applications. Also discussed are the challenges and limitations of outdoor applications of hyperspectral imagingtechnology such as illumination conditions and variations due to leaf and plant orientation.
