Geometric correction and image de-warping

Image distortion can be caused by many factors such as lens distortion (see the optics section), or when the camera views a target at an angle to the image plane. Geometric correction is very processor intensive, but can be essential in some applications to obtain a usable image.

The two following images show the effect of placing the camera at an angle to the target, resulting in the squared grid becoming a diamond shape. Notice the original shadowing. In the right image the distortion is corrected by software.

The next image shows the distorted effect when a label attached to a cylindrical container needs to be inspected. The label is first de-warped in software, simplifying the demand on the inspection using OCR.
