Problems solved by technology

However, this method cannot pre-judge the position of the mark, and needs to use a laser scanner to scan the entire surface of the tire blindly.
On the one hand, the scanning time is long, and on the other hand, the use of laser scanners for full-surface blind scanning makes subsequent mark extraction more difficult
Moreover, the patent application did not provide any specific scheme for logo extraction

Abstract

The invention provides a hub identification detection method. The hub identification detection method comprises the following steps: shooting an image of a hub surface through a camera device; processing the image shot by the camera device to identify the feature contour of the spoke on a hub; calculating an included angle between a hub circle center and a center connecting line of the feature contour; determining a plurality of rotation angles of the hub according to the included angle between the center of the hub and the center connecting line of the feature contour; controlling the hub torotate in sequence according to the multiple rotation angles, so that the marks are moved into the scanning range of a 3D laser scanning device in sequence; after the hub rotates by a rotation angle,controlling the 3D laser scanning device to move to scan the identifier rotationally transferred into the current scanning range; and identifying the identifier scanned by the 3D laser scanning device. The invention further provides an electronic device and a storage medium. According to the invention, the automation and accuracy of hub identification are improved.

Description

technical field [0001] The invention relates to the technical field of appearance detection, in particular to a detection method for a hub mark, an electronic device and a storage medium. Background technique [0002] In order to improve production automation and intelligence, characters and logos are often engraved on some castings. For example, logos or characters such as manufacturer, specification, mold number, customer part number, etc. are engraved on the wheel hub of a vehicle. In order to ensure that the production process is orderly and correct, it is usually necessary to identify the characters or logos on the wheel hub. At present, the commonly used recognition method of characters and logos is manual recognition. However, manual recognition increases labor costs and has relatively large errors, thereby reducing the accuracy of character and logo recognition. [0003] Chinese patent application No. 201810003270.6 discloses a method for identifying car tire marki...
