MUZZLE PATTERN INFORMATION CREATING DEVICE, MUZZLE PATTERN INFORMATION CHECKING DEVICE, MUZZLE PATTERN INFORMATION CREATING PROGRAM, AND MUZZLE PATTERN INFORMATION CREATING METHOD

摘要

A muzzle pattern information creating device for creating muzzle information to easily identify a muzzle pattern. An animal managing device (100) comprises a muzzle pattern image data input section (111) for inputting muzzle pattern image data, an image data storage section (112) for storing muzzle pattern image data, a correction extracting section (113) for extracting a pattern used for forming a muzzle pattern from the muzzle pattern image data and cells divided by the pattern, and muzzle pattern information creating section (114) for selecting a reference region as a root of a tree structure from the extracted pattern and cells, selecting a first node cell adjacent to the root, a second node cell adjacent to the first, one, and similarly third to n-th node cells sequentially without duplication, and creating a tree structure constituted of the root and the node cells as muzzle information.
