植物工場におけるレタス生育状況のカラー画像と正規化植生指標（NDVI）による計測

抄録

Lettuce leaves grown in a plant factory were photographed by a digital camera and a near-infrared camera. We propose an image processing method to investigate the differences in growth depending on the kinds of lettuces and the kinds of LED irradiation. The normalized difference vegetation indexes (NDVI) for the leaves were also measured. We show the effectiveness of the proposed image processing method as nondestructive measurement.
