Title:
SWING ANGLE PLANNING METHOD FOR GROUP-HOLE MEASUREMENT, AND READABLE MEDIUM AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/011779
Kind Code:
A1
Abstract:
A swing angle planning method for group-hole measurement, and a readable medium and a device. The method comprises: acquiring feature parameters of a hole to be subjected to measurement and feature parameters of a measurement probe; calculating a measurement included-angle threshold, and determining an initial condition for iteration and a termination condition for same; executing clustering, updating a cluster set and a measurement normal vector set, and calculating candidate seeds; updating a seed set, and performing iterative optimization; determining whether the number of iterations exceeds a limit; adding the candidate seeds to the seed set; performing iterative optimization until a cluster is converged; and converting the measurement normal vector set into a measurement swing angle set. The time for calibrating a measurement probe can be reduced, thereby improving the on-machine inspection efficiency.
