Setting Example for when There Is No Chatter in the Work
Even when there is a mechanical structure and the
camera cannot be installed from the front, 4-point
position information can be used to compensate for
distortion in the image.
When you specify the four points used for distortion
compensation and specify the positions where those
four points should be as reference positions, the
parameters for distortion compensation are set
automatically. Each time a measurement is made, the distortion is automatically compensated for using these
parameters.
