Abstract

Environment preservations of the forest become world-widely close-up. The remote sensing technologies by satellite have been used for observation of the forest. However, the observation system on the ground is also needed because the remote sensing by satellite is seriously hindered by atmospheric phenomena and detailed data are necessary for precise analysis of the state of forest. Therefore we developed a multispectral infrared camera system for plant healthiness monitoring. The infrared camera system has five infrared bandpass filters. A hue is defined from the five infrared images. We performed several experiments to confirm that the hue changes according as the plant healthiness decline. In this paper, we propose a plant healthiness evaluation method by detecting hue changes with time. Experimental results of observation of hue changes of a plant through a day using the multispectral infrared camera system are shown. The results show that hue in healthiness parts of plants are more stable than in weak parts when the circumambient conditions such as the sunshine condition are changed.
