Method and system for identifying arc-shaped information identifier of rotating part

The invention relates to a method and a system for identifying an arc-shaped information identifier of a rotating part. The method comprises the following steps: S1, acquiring a rotating part image containing an arc-shaped to-be-identified information identifier; s2, rotating the image of the rotating piece, and uniformly rotating the arc-shaped information at different positions to the central axis of the rotating circle center of the rotating piece; s3, converting the arc-shaped to-be-identified information obtained after rotation into linear to-be-identified information; and S4, identifying the linear information through OCR identification software. The system comprises: a shooting device used for acquiring an image of a rotating member; the image rotating module that is used for rotating the image of the rotating piece and uniformly rotating the arc-shaped to-be-identified information at different positions to the central axis of the rotating circle center of the rotating piece; the information conversion
