Multiple-Camera Instrumentation of a Single Point Incremental Forming Process Pilot for Shape and 3D Displacement Measurements: Methodology and Results
Résumé
A multiple-camera system (more than two cameras) has been developed to measure
the shape variations and the 3D displacement field of a sheet metal part during a
Single Point Incremental Forming (SPIF) operation. The modeling of the multiplecamera
system and the calibration procedure to determine its parameters are described.
The sequence of images taken during the forming operation is processed
using a multiple-view Digital Image Correlation (DIC) method and the 3D reconstruction
of the part shape is obtained using a Sparse Bundle Adjustment (SBA)
method. Two experiments that demonstrate the potentiality of the method are described.
