The work of the system is based on the principle of 3D laser scanning of object/ objects with subsequent construction of a 3D computer model and determination of geometrical parameters from the model.
24 pcs of special RFMR625 laser scanners are placed around the moving pipe let to get full 3D model and calculate diameter and roundness.
10 pcs of special RFMR625 laser scanners are placed along the moving pipe let to calculate pipe curvature.
