Description
technical field [0001] The disclosure belongs to the technical field of three-dimensional optical non-contact measurement and metal additive manufacturing, and in particular relates to a single measuring head scanning and repairing device and method for damaged parts. Background technique [0002] The traditional manual repair method is difficult to adapt to high temperature, narrow space, continuous operation, complex damage and other working conditions. The repair quality and repair time are greatly affected by human factors. The existing digital models of defects used in laser cladding repair are mostly obtained by manual modeling, which has the disadvantages of poor robustness, low repair accuracy, and large influence by human factors. Existing 3D optical scanning systems are seldom combined with laser cladding repair systems for remanufacturing repair of damaged parts. Multiple probes will increase the difficulty of realizing multiple groups of black and white camera c...
