Mushroom Object Growth Monitoring Method Using Image Processing Technology

摘要

The present invention relates to a "mushroom object growth monitoring method to which image processing technology is applied" that automatically detects the state or size of mushrooms grown in a mushroom cultivation farm such as a smart farm so that the harvest time or problematic part can be checked in real time. will be The mushroom object growth monitoring method to which the image processing technology, which is the technical idea of the present invention, is applied, generating an image including a plurality of mushroom objects using an imaging device and obtaining an original image converted into a grayscale image; obtaining an image to which the histogram smoothing operation is applied by performing a histogram smoothing operation for adjusting the contrast of the original image; obtaining an open image by reconstruction by performing an open operation by reconstruction on the histogram smoothed image; obtaining a closed image by reconstruction by performing a closing operation by reconstruction on an open image by reconstruction; extracting a foreground marker image composed of the mushroom object by individually blob processing after calculating the local maximum values of the mushroom objects displayed separately from the background among the closure images by the reconstruction; performing an erosion operation on the foreground marker image to clarify an ambiguous boundary between the blob-processed mushroom objects; generating a binarized image by blob-processing each portion exceeding a predetermined threshold in order to extract a background region from the closure image by the reconstruction; generating a watershed ridge image having information on a gradient magnitude from the binarized image; and detecting a mushroom object by performing a water ceding transformation using the foreground marker image and the water ceding ability image as variables. A mushroom object of a predetermined size can be clearly detected from a plurality of mutually overlapping mushroom images implementing the method according to the present invention. In addition, it is possible to easily determine the size of the mushroom through a terminal at a remote location, and there is an advantage in that it is possible to immediately determine whether the mushroom is harvested based on the detection result.
