The measurement system analysis is a part of the quality assurance. In this field, the measuring device capability evaluation has an importance. Optical 3D scanner, as a noncontact device, is used for digitization and measuring. Aim of this paper is point to the possibility of measuring a small object, namely hard metal rod, using optical scanner. The issue was the evaluation of measuring capability of the GOM ATOS Triple Scan II optical 3D scanner when measuring the geometric characteristic of runout with using of various measuring volumes. Measuring of a small object is often difficult due to ensuring the measuring repeatability (precision) and high accuracy. Statistical method of repeatability of measurements was used for capability evaluation and for its expression in the form of capability indices. Based on the results it was able to confirm or refute the capability of this scanner to provide relevant data during measuring a small object. |
