Abstract:
An apparatus and method for controlling lighting in a plant factory are disclosed. The apparatus includes a weight calculation unit, a height calculation unit, a light information extraction unit, and a distance control unit. The weight calculation unit calculates the weight of at least one crop being cultivated based on a sensing result received from a weight sensor disposed in a crop cultivation bed. The height calculation unit calculates the height of the crop based on information about the growth of the crop corresponding to the weight of the crop. The light information extraction unit extracts information about artificial light corresponding to the height of the crop based on the information about the growth of the crop. The distance control unit controls the height of an artificial lighting device based on the information about artificial light.
Abstract:
An apparatus and method for non-destructively diagnosing crop growth using terahertz waves are provided. The apparatus includes an information extractor configured to extract status information on a crop from information on an image of the crop taken using terahertz waves, a database configured to store growth-stage-specific information on the crop, and a status determiner configured to compare the status information on the crop extracted by the information extractor with the growth-stage-specific information stored in the database, and determine the degree of growth of the crop.
