Calibration based on part set-up measurement for on-machine inspection using vision

Abstract : Integrating inspection procedures in the machining process contributes to process optimization. To be highly efficient, inspection operations must be performed in the same frame as machining operations. Within the context of on-machine inspection using vision, a method of calibration based on part setup measurement is proposed in this paper. The measurement frame thus coincides with the CAD/CAM frame in which the CAD model is built. The CAD-based calibration is performed by using 3D features of the part setup , which are easily identifiable in the 2D picture of the scene. The robustness of the method with regard to 2D feature identification in real environment is assessed thanks to Monte-Carlo simulations.
