The present invention provides a system for identifying individual crowns of individual fruit trees using aerial images. A crown identification deviceof the present invention includes an identification criterion determination unitand a crown identification unit. The identification criterion determination unitincludes a first image acquisition sectionthat acquires a first aerial image including a plurality of individual fruit trees in a deciduous period in a fruit farm field, a skeleton extraction sectionthat processes the first aerial image to extract a whole crown skeleton including the plurality of individual fruit trees, a vertex extraction unitthat extracts vertexes of each crown skeleton corresponding to each individual fruit tree, and an identification criterion extraction sectionthat extracts a crown candidate region of a minimum polygonal shape including all the vertexes as an identification criterion for each individual fruit tree and extracts a centroid of the crown candidate region. The crown identification unitincludes a second image acquisition sectionthat acquires a second aerial image of the fruit tree farm field at the time of identifying a crown at the same scale as the first aerial image, a whole crown extraction sectionthat processes the second aerial image to extract a whole crown image including the plurality of individual fruit trees, and a crown identification sectionthat collates the crown candidate region and the centroid of the identification criterion with the whole crown image to identify a crown region of each individual fruit tree in the second aerial image.

Crown identification device, identification method, program, and recording medium

A system acquiring data for phenotyping on a farm field where crops are bred. The device includes: an information storage unit storing farm field information, an imaging condition, and aerial images of the farm field linked with imaging condition; a classification unit classifying the aerial images into a plurality of image groups having different imaging altitude ranges on the basis of an imaging altitude included in the imaging condition; an image processing unit creating image-processed data from at least one of the image groups and imaging condition and analyzes a trait of in the farm field from the image-processed data; a visualization unit visualizing image-processed data obtained in the image processing unit; a processed information storage unit storing, as processed information, data obtained in the image processing unit and visualization unit; and an output unit outputting data obtained in the image processing unit and the visualization unit.
