Paper Abstract

Environment preservations of the forest become world-widely close-up. The remote sensing technologies have been used for observation of the forest. However, the remote sensing by satellite is seriously hindered by atmospheric phenomena and cannot get the detailed data, which are necessary for precise analysis of the state of forest. So the observation system on the ground is needed. In this paper, we develop a multispectral infrared camera system to investigate the continuous spectra of mid-range infrared whose wavelengths cover around 3000nm to 5000nm. We define hue value in the case that the number of primary image is more than three. An algorithm to calculate the hue value from multispectral infrared images is proposed to obtain spectrum change of plants. An experiment of observation using the multispectral infrared camera system when the plant is growing week from cutting water off is shown.
