摘要：

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. © 2020 The Institute of Electrical Engineers of Japan.
