Images obtained with stereoscopic mirrors and used for estimating of distortions (a). The white rectangle located on the upper edge of the field corresponds to a piece of adhesive tape used to fix the calibration pattern onto the machine support. Digital images printed on the calibration plate (b). The distorrions of the whole optical chain is assessed by registering the left and right parts of both pictures.
