Article signing method and device based on image recognition, equipment and storage medium

The invention relates to an artificial intelligence technology, and discloses an article signing method based on image recognition. The method comprises the following steps: acquiring monitoring pictures of a preset region at a first moment and a second moment, respectively carrying out region division and corresponding coding on the two monitoring pictures, selecting two regions with corresponding codes one by one, respectively extracting global features and local features of the two regions, calculating a difference value of the two regions with corresponding codes according to the extracted global features and local features, determining that an article in the region is not signed when the difference value is smaller than a difference threshold value, determining that article in the region is signed when the difference value is greater than or equal to the difference threshold value, and reminding the user. In addition, the invention also relates to a block chain technology, and a monitoring picture can be
