Achieving 0.02mm accuracy in 3D reconstruction with advanced structured light calibration for metrology-grade scanning systems
An aerospace manufacturer required ultra-precise 3D scanning for quality control of turbine blades and complex engine components. Their existing coordinate measuring machines were too slow, and commercial 3D scanners lacked the required accuracy for critical tolerance verification.
CalibWorks developed a custom structured light calibration system that achieves 0.02mm accuracy across the entire measurement volume. The solution includes advanced projector-camera calibration, phase unwrapping algorithms, and real-time point cloud generation with automatic mesh reconstruction.
