Abstract
A large crane 3D vision gantry type beveling robot workstation relates to crane welding technology field, including walking track, self-propelled gantry, six-axis robot, scanning cutting device and vision calibration device. The scanning cutting device integrates 3D laser scanner, line laser precision scanning sensor, main and auxiliary cutting head, realizes hierarchical modeling combining global scanning and local precision scanning. The vision calibration device is distributed along the gantry beam, establishes global coordinate system reference and corrects clamping error. The application is equipped with intelligent bevel decision system, adopts variable cross-section bevel recognition algorithm based on multi-scale semantic segmentation and geometric prior constraint, through adaptive point cloud denoising, four-class semantic segmentation, B-spline trajectory fitting and CAD prior parameter inversion, accurately identifies bevel structure and generates smooth cutting path.
