Abstract: The present invention discloses a credible fruit traceability method and device based on fruit texture atlas and blockchain. According to the present invention, images of fruit pedicel part and fruit navel part of a single fruit are obtained, and the images are grayed and normalized to be converted into rectangular images; features are extracted from the rectangular images, respectively, and are encoded to obtain a fruit pedicle feature code table and a fruit navel feature code table; the two feature code tables are subjected to a merging operation to obtain a combined bidirectional feature code table, thus forming a unique fruit texture atlas. By processing the fruit texture atlas, the fruit texture atlas information and related information are stored on the blockchain.
