Comparison of the results of metrological tests obtained from X-ray computed tomography and optical 3D scanner

The launch of new methods in the technical metrology area is a material factor determining the quality of the products. The paper presents the methodology of analysis of metrological tests conducted with the use of computed tomography and an optical 3D scanner. These devices allowed us to obtain virtual objects and conduct 3D spatial analyses. The paper presents the operating principle of these devices and analyses their capabilities based on selected castings. The results of the tests are presented with the support of determined dimensions and colour maps on the model surface. The accuracy of measurements in individual methods was assessed.
