Abstract

This paper proposes a calibration approach of linear scanning sensor (LSS) for the three-dimensional measurement of turbine blade surface. The linear scanning method is an effective method of complex surface measurement. It is characterized by non-contact, large measuring range and high measuring efficiency. But in practice, the measurement accuracy is usually limited by the installation pose. To improve the measurement accuracy, a practical calibration strategy is presented. The experiment was carried out using a standard cylinder to calibrate the LSS. By introducing the calibration method, the experimental data were improved in simulation. Finally, in the application of an aero-engine blade measurement, the calibration method was used to calculate the pose error of the LSS. By comparing the measurement result with a CMM of a blade, the measurement accuracy is significantly improving.
