Industrial CT technology is more and more widely used in the field of digital measurement and engineering because of its unique advantages of measuring and analyzing in non-contact and non-dama-ging conditions.However,due to the lack of corresponding calibration standards,the measurement re-sults of industrial CT are difficult to trace.This paper systematically analyzes the metrological characteris-tics of industrial CT in dimensional measurement,and verifies and analyzes the uncertainty through tests.
