How accurate is a 3d scanner for high-precision tasks?
accurate 3d scanners such as Creaform MetraSCAN 3D apply laser triangulation to achieve absolute accuracy of ±0.025mm (ISO 10360-8 standard). For aerospace uses, when scanning turbine blades (150mm chord length), A point cloud density of 1,600,000 points per second is able to detect cooling holes as deep as 0.02mm (±0.03mm required by ASME B89 standard). …
