| Summary: | 碩士 === 國立臺灣大學 === 生物產業機電工程學研究所 === 93 === This study is aimed to develop a multi-functional monitoring system based on remote spectral imaging and environment sensing for seedling production in the greenhouse. The spectral images were grabbed with exposure time and signal gain controls through IEEE-1394 interface, and by a color camera and a monochrome camera with optical filter at 780 nm. The controlling program was developed to grab the good quality images using the automatic exposure algorithm with Matlab 6.5 and LabVIEW 7.1 software. To obtain necessary spectral information regarding tray locations and seedling growth on benches, a serial image processing procedures, including spatial calibration, image stitching, gray-level calibration and image segmentation were developed. The data of tray positions were transferred to the look up table (LUT) and delivered to the water management module through the datasocket server and wireless network. Besides, the environment sensing sub-system, including temperature, relative humidity, and photo-quantum measurements, was also developed with the PCI-6023 interface to analyze the spatial distribution of these parameters in the greenhouse. The information of environmental status will provide a better management for seedling growth. The further goal of the study is to provide a basis for developing an automatic seedling production system.
