Abstract
A brake disc wear degree measuring method comprises: obtaining a brake disc image comprising a laser pattern (); extracting the laser pattern from the brake disc image, and generating a projection depth point cloud map according to the extracted laser pattern (); identifying the projection depth point cloud map by means of a point cloud map identification model to obtain a matching sample, and determining a measurement feature of the matching sample as a measurement feature of the projection depth point cloud map (); determining a position of a reference point in the projection depth point cloud map according to the measurement feature (); determining a position of a measurement point in the projection depth point cloud map according to the measurement feature (); and determining, according to the position of the reference point and the position of the measurement point, a difference value of the laser projection depths of the reference point and the measurement point, wherein the difference value is used for representing a wear degree index of a brake disc ().
