The application discloses an OTA cross-version incremental synthesis upgrading method and system based on a version graph, and belongs to the field of vehicle OTA upgrading. The method comprises the following steps: step S1, acquiring upgrade package metadata of all versions to construct a version dependency graph; step S2, synthesizing an incremental package according to a current vehicle version, a target version and the version dependency graph; and step S3, performing OTA upgrading on the vehicle through the incremental package. The application solves the problem of intermediate change loss during cross-version upgrading by constructing a version dependency graph and dynamically synthesizing a differential package.

This application belongs to the field of medical device technology and relates to a scanning rod, comprising: a rod body, which includes a first rod segment, a second rod segment, and a third rod segment connected sequentially; one side of the first rod segment has at least one polygonal protrusion, and the top of the polygonal protrusion has at least one identification object for scanning by an external scanning head; the identification objects on the first rod segment have a unique corresponding coding combination; the coding combination includes the number, shape, and placement position of the identification objects on the first rod segment, or a combination of the three; or, the first rod segment includes a first region and a second region, and the coding combination includes the number, shape, and placement position of the identification objects in the first and second regions, or a combination of the three. The technical solution provided by this application enables unified management and rapid positioning in actual operation, facilitating rapid and efficient panoramic scanning within a limited field of view.
